Shedding Light in the Night: How Solar Energy and Mobile Charging Improves Quality of Life in India
Shedding Light in the Night: How Solar Energy and Mobile Charging Improves Quality of Life in India
In this installment of Digital Diversity, Gwen Kidera – Project Associate at S3IDF (Small Scale Sustainable Infrastructure Development Fund) – explains how their non-profit organisation provides underserved communities with Integrated Energy Centre carts (IECs) equipped with reliable solar powered lamps and mobile charging stations. Access to light and mobile technology improves the quality of life in these communities by allowing them to continue working after dark.Digital Diversity is a series of blog posts from kiwanja.net featuring the many ways mobile phones and other appropriate technologies are being used throughout the world to improve, enrich, and empower billions of lives. This article was curated by Gabrielle LePore, our Media and Research Assistant. You can follow Gabrielle on Twitter at @GabrielleLePore and kiwanja.net at @kiwanjaBy Gwen KideraSolar lights switch on in the tents of nomadic North Indian residents as the sun sets over the Thanisandra slum in Bangalore, India. Men pick up their tools to carve drums, which serve as the community’s primary source of livelihood, and women crouch to cook supper as the smell of firewood permeates the thick night air.Wahida, a resident in the camp, returns from the community-owned cart with a rented and freshly charged solar lamp. She hangs it in the centre of her tent above the heads of her six children and her husband who busily works on the ornate drum on his lap. She relaxes because the light allows her husband to work into the night carving drums that are sold to earn additional income, and her children keep safe from pests that would otherwise creep into the poorly lit area. Reliable and safe lighting was a luxury beyond the reach of most residents before the community-owned and operated Integrated Energy Centre (IEC) arrived.In March 2013, SELCO Solar Pvt. Ltd. (SELCO India), an organisation whose mission is to improve the quality of life in underdeveloped communities through sustainable methods, worked with S3IDF to establish a waterproof and durable solar-powered IEC cart to provide lamps and mobile charging to 30 of approximately 80 households in Thanisandra. The nomadic community, which has been moving as a unit across the country for generations, can take the cart with them wherever they go, ensuring many years of reliable lighting. Once they pay off the initial capital costs of the cart, they can own it and lend the lamps to community members without cost.Before the IEC, families spent a large portion of their earnings on black market kerosene which posed health hazards such as increased risk of burns and the release of unhealthy fumes. Now, families spend less than US$2.50 a month for up to eight hours of solar light each evening. In addition to the cart, SELCO India and S3IDF are exploring ways to connect the community’s drum production to viable markets, thereby increasing residents’ incomes.The centre in Thanisandra is just one of 18 IECs under development across the state of Karnataka. Each centre is created based on a needs assessment and tailored to meet the community’s specific circumstances. Although the centres vary in services and business models, at heart they are all solar-powered community centres that provide the underserved with resources to which they otherwise would not have.IECs are built within communities which are off the grid and lack access to electricity. They not only provide much needed energy but they also have the ability to supply useful products, such as solar lanterns, small appliances and tools, mobile charging, larger productive-use technologies – grain mixers and grinders – community TVs, cooling/heating systems, as well as resources for education, health, awareness and livelihood training.IECs offer educational services including audio-visual aids to books, and computers to DVD players, and other basic literacy programs. The IECs can also improve public health by providing solar charging points for ultrasound devices, vaccine boxes and refrigeration for medicines. Other resources include ticket booking and printing, Internet services for obtaining identity cards and sending bill payments, and access to agricultural and trade-related information. As if that weren’t enough, IECS also offer community members the opportunity to enroll in vocational training programs, including classes on computers, sewing and fruit drying.The people who benefit from the IECs run them, and they are designed to be operationally sustainable with revenue generated by the IECs covering all maintenance and operating costs.The implementation of the IEC cart in Thanisandra improved the quality of life of the entire community. “Now we can easily make 20-30 more drums after dark, and I can even finish my quilting without letting my housework suffer”, Wahida explains. “It feels different since it’s the first time we have had the luxury to work like this.”Wahida is hopeful for her future and that of her family and community. She would like to see an increase in demand for their drums, which could become a reality with SELCO India and S3IDF’s help.When asked how the solar lights have changed her circumstances, she smiled and proudly stated, “With the light, even our tent starts looking like a palace, it makes us feel like our dreams can come true.”Gwen began exploring the field of social entrepreneurship in 2009 while in South Africa on a field study program through the Social Enterprise Institute at Northeastern University. She assisted in giving business development support to local entrepreneurs from the townships around Cape Town over the course of two trips. She went on to study microfinance in Belize and work with a group of students to determine the effectiveness of a microfinance institute’s training programs and causes of default among Haitian borrowers in the Dominican Republic. She spent a summer working for the Clinton Health Access Initiative, and in 2011 worked in Meru, Kenya for the Miriam Kanana Mubichi Foundation where she taught health and art classes, advised a women’s textile company, researched malnutrition at the local hospital, and arranged school feeding programs.In 2013, Gwen became a Project Associate at the S3IDF, a nonprofit organisation based in Cambridge, Massachusetts. Members of the organisation work to reduce poverty in developing countries by supporting small scale enterprises that meet basic infrastructure needs and providing opportunities for economic advancement. She is an avid traveler and enjoys documenting her trips and getting to know the local culture through photography and blogging.This post originally appeared at Newswatch.

Outdoor Solar Lights Are Not Working?
yes first you checked that whether you put batteries correctly or not1. solar storms pose a threat to electric grid?The massive magnetic flux acting on a wire induces a current, which, if not shielded against, can cause considerable damage. I am informed that a huge solar storm in the 1800s, before we had an electricity grid, caused sparks to be emitted from circuits which were not even connected, giving electrical shocks to telegraph operators. If this happened to nuclear reactors, it would stop the pumps cooling them, causing disasters on the scale of Fukushima no. 4. solar storms news and articles - Natural News Mar 20, 2012 ... solar storms news and articles. ... Solar storms could bring down modern civilization.2. Why is solar insolation so important?'Solar insolation' is redundant b/c the word 'insolation' is derived from the phrase 'INcoming SOLA radiaTION.' The sun's energy drives the weather...the ocean currents...flora...and fauna. Insolation is so important b/c without it... life on this planet...as we know it...would not exist.3. Invalidation of the Solar Nebula Theory?No, it does not , but it does suggest something that had not previously been considered: it's possible for Jovian planets to migrate inwards from where they were originally formed4. what are the different types of solar power?i do not know i did not even know there were different types of solar. or are you just playing with me?5. How can I calculate the rate of power consumption of a solar car along a known route with changes in elevation?Not sure if this approach is in the format you need, but it might help. The work required to go uphill by a height $y$ is$$W=mgy$$where $m$ is mass and $g$ is gravitational acceleration. Assuming mass and gravity are constant, we can differentiate this equation with respect to time to get:$$dotW=mg fracdydt$$we can also use the chain rule to rewrite it as$$dotW=mg fracdydx fracdxdt$$in which $x$ is the horizontal distance traveled. Then, $fracdxdt$ is just velocity, so the equation reduces to $$dotW=mgv fracdydx$$You already have the data for $fracdydx$, so you can factor out the velocity and insert this equation into your first equation for total power consumption:$$P_w = (F_air F_roll mg fracdydx ) cdot v $$6. Is A Solar Dyson Sphere Habitable?I am not a big fan of the spheres and I have no solution for the gravity issue, but I will make a fake answer to make some points about the energy issues that are really bit too long to be comments.Can be anything you want within upper and lower bounds set by engineering and the total energy of the star. There are lots more variables than trivial models assume since the structure of the sphere is realistically more complex. There is no one-to-one connection to the temperature of the inner shell. You can use insulation to make the outer shell cooler than the inner shell. You can use heat pumps powered by photoelectrics to make it hotter. Or more robustly simply connect it to hot areas of the inner shell. Yes, I said hot areas, there is no reason why areas of the inner shell must all have the same temperature. You can give different areas different albedo. Or simply link different areas on the inner surface to areas of variable size on the outer surface. If areas A and B on the inner surface have the same area but the outer shell radiator A is connected to has ten times the area of the radiator B is connected to, A will be cooler. The sphere is not, cannot be, made from homogeneous mass, it has structure. Since the temperatures of inner and outer shell are not directly linked, you can use insulation to make the sphere habitable at a distance higher than usual or cooling to make it habitable closer. So you do not need to worry about what the insolation or habitability of a planet at that radius would be. For example if the sphere is larger, you can replace parts of the inner surface with mirrors reflecting light to the inhabited parts. If smaller you might give the inhabited parts higher albedo, so that radiation is reflected to the uninhabited parts.There is no known way to get a comfortable gravity to the inner (or outer) surface. Nor should there be. a Dyson sphere is not a habitat, it is an energy collector. You should build your spin gravity habitats separately and just use the power collected by the sphere to power them. Or just use planets. Technology needed for a Dyson sphere should allow building planets. And the mass needed would allow building lots of them. Just because having six planets on the same orbit is not stable, does not mean you can not make it so. It would be easier than building a Dyson sphere. And making the planets habitable would be much easier. Like I said in the beginning this was not really an attempt to give an answer. Just some comments too long to fit into actual comments. You should not expect any of what I said to be true or accurate. Just some food for thought.
The Best LiFePo4 Battery for Solar Street Light
For most renewable energy systems, as like solar street light, the most important battery characteristics are the battery lifetime, the depth of discharge and the maintenance requirements of the battery.Some solar street lights produced with Lead/VRLA/AGM batteries by default. However, the total cost of ownership (TCO) of these types of batteries is much higher than that of lithium batteries - even though lithium batteries may appear to be more expensive at first glance.Lithium battery VS Lead-AcidSo, why we choose lithium batteries instead of Lead-acid?FlexibilityThe same lead-acid battery is heavy in weight, larger in volume and small in energy density. The lithium battery is small in size, light in weight and easy to transport. Compared with the lithium-ion energy storage system and lead-acid gel battery used in solar street lights, the weight and capacity are about one-third of lithium batteries. As a result, transportation is easier and is costs also reduced.DurabilityLithium battery has higher energy density and longer service life. The lithium battery cycle life of more than 2500 times, lead-acid battery cycle life of 800 times; the energy density of lithium battery is around 150Wh/kg, lead-acid battery is about 40Wh/kg; the charging time of the lithium battery can be full within 4 hours, and the lead-acid battery is generally full around 6 hours;AccessibilitySolar street lights using lithium batteries are easy to install. When installing traditional solar street lights, a battery pit needs to be reserved, and the battery is placed in the ground box to seal it, or install the lithium battery on the bracket, using a hanging type or a built-in type.Then, it is easy to maintain and replace. The lithium-ion solar street lights only need to remove the battery from the pole or battery panel during maintenance, while traditional solar street lights need to dig out buried batteries, which is more troublesome than lithium-ion solar street lights.EfficiencyLithium battery charge and discharge electrical energy efficiency is better, lithium-ion battery charge and discharge energy conversion efficiency can be greater than 97%, and lead-acid battery charge and discharge energy conversion efficiency is about 80%, the same lithium battery than lead-acid battery volume Small, the volume of a lithium-ion battery is about 2/3 of the volume of a lead-acid battery;Why do we recommend LiFePO4 (LFP) batteries for solar street light?Today, many electronic systems are backed up or operated by solar energy and solar battery storage. These systems, such as closed-circuit monitoring systems, remote alarms, and environmental monitoring systems, may require direct current (DC) power storage, as well as other systems such as Motorola's vehicle, marine. In the past few decades, Lead-acid (AGM) batteries have been their product of choice for decades, and now Lithium iron phosphate (LiFePO4, LFP) batteries play an important role.The systems using AGM batteries require replacement once a year to ensure reliability. Generally, the labor cost of replacing AGM batteries exceeds the cost of the product itself, especially in Australia, Europe, North America and other places. The risks and hazards of frequent battery replacement cannot be ignored.Learn more about batteryKeep an eye on Grepow's official blog, and we'll regularly update industry-related articles to keep you up-to-date on the battery industry.Grepow: grepow.com/Grepow Blog: grepow.com/Related articles:Lithium Iron Phosphate (LiFePO4) vs Lead Acid BatteriesWhat is a forklift battery?·RELATED QUESTIONWhy don't hotel rooms have ceiling lights?My hotel building is over 100 years old, so we have ceiling lights. We also need a ladder to change a bulb 11' from the floor. It can take 20 minutes for 1 bulb! This is one reason that we have changed to the longer lasting (and more economical) low-energy bulbs.I would be delighted to have wall lights instead. Retro-fitting them would however be even less economically sound.Higher than average ceilings mean ladders to change the bulbs in ceiling fittings, and this extends the maintenance time and convenience for staff enormously. Even normal height ceilings mean that a chair is needed to swap a bulb out. Wall fittings are so much more convenient for both staff and customers, reducing the time taken to get light again!As Michael Forrest Jones says - anything other than a simple bulb swap requires the power to be cut to the whole circuit (which may be more than just a few rooms). This makes it very awkward to do emergency repairs after dark! -- Been there done that... Go with wall fittings that can be isolated in-room!In short:I have ceiling lights.I don't like them, as they are awkward for maintenance.Replacing them would be expensive and extremely difficult - basically a total rewire of the hotel lighting system.Design engineers are not stupid. they note the first 2 points!

A 2 Watt panel is about the right dimension. It will begin spinning at cut down vigour output however not acquire the rated speeds unless peak vigor from the panel. The perspective should be satisfactory.The Guardian asks: Are we really going to let ourselves be duped into this solar panel rip-off?I've often thought about crooks bypassing meters myself. But surely to get paid for the electricity you've stolen and sold to the grid would require an "Import/Export meter". At present obviously we only have an "Import" meter to enable our bill for usage of electricity to be measured. Surely there's only one cable? The same cable surely imports on demand and exports when the householder's electricity production exceeds demand, thus the "excess" is fed to the grid via the "Export" meter? It's not April 1st is it?How much would be the investment for solar panel which runs 2 Air conditioner?Solar Air Conditioner IndiaHow can you have solar panel home?Not easy to convert it into AC power because it produces DC power that is different than from wall outlet power source and its voltage is very low, like 0.5V per cell. Must need first to charge a very big battery bank, and then convert the battery power into AC power with a converter before able to power a fridge. Solar penal contains many small solar cells, they convert sun light ( the only free light source) into electricity directly with a very low efficiency like 5%. Mount them with a strong frame on top of roof facing to the open sky to catch the bright sun light, under shadow would not work well or produce no electricity. A VERY EXPENSIVE SYSTEM AND REQUIRE TAKE CARE OF IT DAILY, AVERAGE LIFE IS 5 YEARS.If someone shined a flashlight at a solar panel, would it generate electricity?It may generate electricity. But it would not generate as much power as your flashlight would use. Your flashlight produces light. It also produces heatWould a solar panel that generates 50 kW of power charge a battery to 500 kWh in (about) 10 hours? (I'm assuming there would be some losses, but I wanted to see if that was correct for most cases)You are theoretically correct, except that it is too much to expect charging at topmost power of 50 KW non-stop for 10 hours, starting from discharged condition. You will never get sun for this long period and that too at this level.Sunlight will be available for maximum 5-6 hours a day, and intensity depends on season, weather and other conditions. Intensity keeps varying over a day, over a season for the same time.So you will have to charge it at a higher rate, or be content with the charging you get in a day, and wait for few days for complete chargingI have a 30 watt solar panel that puts out 1.8 amps. What size battery should I get?regular car battery will work but you will need more than one . may be 30 or more depending how much eletcricity you need when there is no sun or not enough sun. It depends on a number of factors do you have A.C. electric oven stove electric dryer ect.An appropriate voltage regulator / limiter for a 5V solar panel for USB charging?My first reaction is to put the two panels in series, then use a off the shelf buck regulator chip. If the two panels can not even put out 6 V or so in series (3 V per panel), then there is so little power available that it does not matter if the output is just shut offHow to convert a 10-Watt solar panel into 3v & 3 amp?I saw somewhere an answer to a question that seemed to apply quite usefully to your question. I am posting it here with slight modification. Note that this is not my work - just seems mainly useful.Comments in [square brackets] are mine.[These are all good points worth noting that many people miss]To get 9W out of a 10W panel you need bright mid-day sun, the panel must be clean AND pointed towards the Sun and 90% SMPS efficient Buck Regulator that utilizes the 17.3V max power level of the array.[worth noting]Not all SMPS will do this as the switching current can be much higher than the average current thus drop your PV Array well below Vmax power, so more Power management design is required, such as a 17.5V battery design to regulate the input voltage. If you do not , you will be lucky to get 5W.[Here is a useful TI web bench simulation that somebody has set up that matches your need.]You also want an Econo mode for cloudy days for more efficiency.The TPS54526 is one good solution.will this solar panel power this fan through dc current?Yes,you will need a good storage battery to carry it through the nightI want to make a solar panel for 240 volts, help me out please?If you are in Malaysia, I am not sure why you need a heater, except maybe a water heater. For that, use a solar heater directly. For the electricity, the most cost-effective way to do it is to stay connected to the grid, and offset your bill with solar. That way, you do not need to oversize the solar for contingencies. There will be compromise in your lifestyle, everything that plugs into the wall today will still plug into the wall and work fineis 12v 800w solar panel enogh tu run a 12 cubic refrigerator?A 12 cubic foot fridge operates on 110 volt power, not on 12 Volts, you will need a generator to power a fridgeWhat would a 60 watt solar panel power? How many watts for a small home?You can run a 60 watt light bulb when the sun is shining. Or your can charge a battery and then run the 60 watt light bulb at night. It theory if you had 8 hours of sun you would be able to run the bulb for 8 hours off of battery. In reality because of losses you will not get 8 hours of bulb running timewhat all can a 200 watt solar panel power up?I am going to assume you have a 200 watt continuous wattage converter on your deep cycle batteries. Overall there is not a definite answer as much as a recommendation by doing research of items around the house that you may want to run. The best way to do some figuring is to take the wattage requirements of devices around the house. The most common CFL lamp is 13 watts 120 volts. You can extend the charge life by using 12 volt LED lighting, which would bypass the inverter (always a good idea). Ditto on a fan - a typical modern 20" box fan draws 50-100 watts depending on speed. A laptop computer can draw over 100 watts alone when under a full load, but taper off when not needed. The list could go for miles. A Kill-A-Watt wattage meter is a must have for checking items around the house for their actual current draw. Many ratings are maximum ratings, not the actual real-world normal draw. Also look into more and more direct 12 volt items. Then you can bypass the inverter, and that is a plus as the inverter is not totally efficient.Does anybody know if there are any courses for solar panel installation, and/or what trades you need for this?What you ought to recognize will depend on WHAT sort of installations you are going to be operating with. In regular, for business you wish to have fundamental mechanics and wiring. For house, you may additionally want a few carpentry, roofing, preserving structural integrity, plumbing, and so on. In side it additionally will depend on what sort of sun installations you are doing, (vigour, air warmers, water warmers, and so on.)Is this how much this solar panel collects an hour?it collects 135 watts an hour ( think of it as gallons in a pail) at 17 volts ( the pressure in the pipe filling the bucket ).....yes all you tech savy people I know its not quite that simple...... so when that panel is operating at peak efficiency ( which depending on how far north you live is anywhere from 2 to 6 hours a day) you could charge a 12v battery at 8 amps....of course at 17 volts you would fry a 12v battery really quickly; you need to buy an regulator as well.......or if you were running the panel to an inverter you could power two 65 watt light bulbs.I have a few solar panel stick in the ground night lights that beep in the evening but don't give light. Why do they beep?My guess is, they only beep in the daylight hours, because their internal battery is shorted or otherwise non-functional, they have no or insufficient voltage to operate at night, and cannot charge in the daytime.And maybe they screwed up when assembling, and those few were put together with "make an annoying beep when voltage is present" parts, rather than functional "solar-recharged night light" partsanyone Arco solar panel ASI 16-2000 watts ?These are around 25 years old The following link is for some test done on these old modules that found them to be about 30W. (Actual wattage will be dependent upon incoming sunlight) Starts on page 5would wiring a solar panel and grid tie inverter to the house wiring save electricity?NO, it just changes the sourceCan I charge my 12v deep cycle battery with any size solar panel?Yes I use a 50 watt panel to charge my boat batteriesdoes sunlight in winter have the same amount of power for a solar panel?Yes it will. The reason is that the panel, being pointed directly at the sun, will have the same surface area regardless of the season. The earth on the other hand is tilted at about 23 degrees, so during the winter the sunlight is spread over a greater area than in the summer, so it does not warm the air as much and hence, colder weather. By maintaining an angle perpendicular to the sun at all times, the sunlight is never spread out. Although you will have to adjust it throughout the year to maintain that angle, as the earth will 'tilt' beneath it.Could a solar panel, essentially power itself?No, because energy is lost through dissipation and through the conversion process. With mirrors you might be able to reduce this effect.Can someone explain this microcontroller ADC interface (for reading solar panel voltage)?What is the role of the pnp transistor network?It's a differential voltage to current converter followed by a load (R34 and R35). The voltage between P and P- sets a voltage across R31. This (minus 0.7 volts) sets a voltage across R33 and that causes a current to flow out of the collector (largely irrespective of what load the collector has). Given the values of R33, R34 and R35, whatever voltage is set across R33 appears across R35 but, reduced by 3:1. Importantly, this voltage is ground referenced making it suitable for the ADC to make sense of. So there is level shifting involved

Poor Lighting Blamed for Human-leopard Conflict
Forest department has blamed poor lighting and lack of toilets for increasing chances of man-leopard conflict.After a recent incident where a three-year-old miraculously escaped from falling prey to a leopard at a tribal hamlet inside Aarey colony, the forest department has blamed poor lighting and lack of toilets for increasing chances of man-leopard conflict. The department will also write to BMC and the dairy department as Aarey Colony falls under its jurisdiction to take up the matter.On Wednesday a team of forest officials who are part of the Thane leopard rescue team along with wildlife biologists who are part of Mumbaikars for Sanjay Gandhi National Park (MSGNP) team visited Chafyachapada where the incident had occurred on Monday night for an awareness programme.Three-year-old Pranay was attacked by a leopard while he was following his mother Pramila Rinjad. Rinjad who did not know that her son was following her was headed towards a makeshift toilet at Chafyachapada. When she came out she spotted Pranay and saw a leopard pouncing on him from the bushes. Without thinking about her own safety, she shouted and rushed towards the big cat forcing it to run away. However the child had already received severe injuries.Instead of blaming the leopard the locals claimed that such incidents were waiting to happen due to poor lighting, lack of proper toilets. They also blamed poor waste management.Meanwhile Sunil Limaye, Chief Conservator of Forest (CCF) Territorial said, "Our staff have been patrolling the area. They even spoke to locals who emphasised on the need to have proper lighting so that people walking in the dark can be alert and not come across a leopard accidentally in dark."Limaye said, "These areas need to be well-lit. Even solar lights can be installed. Toilets must be built to reduce chances of human-leopard conflicts."Seven out of 27 hamlets in Aarey Colony still do not have electricity. These include Chafyachapada, Khadakpada, Jivachapada, Vanichapada, and Navapada.
The Importance of Solar Street Light Green Building Canada
The Importance of Solar Street Light Green Building Canada
1/14/2017· Since solar panels can be used to distill water in places where there is limitation on clean water access and supply electricity in places that are off the grid, they are considered diverse when it comes to applications. Solar panels as well as solar energy are being used even in building homes which expands the application of this energyHow to determine the brightness of solar street light? -RS standards | Socreat Electronics Technology LimitedIn recent years, with the deterioration of the global environment, solar energy resources have received more and more attention. For this reason, many countries are increasing the layout of solar energy resources. As LED technology is advancing with each passing day, its luminous efficiency is making an amazing breakthrough. So how do we judge the brightness of solar street light? In the market, due to the lack of understanding of the technology of the solar street light industry, users only roughly understand some simple mainstream configurations in the market, such as: how many watts are required for solar panels, how much capacity is required for batteries, and how many lamp beads are required. So you can only judge the brightness of the lamp with these parameters which are not so practical. This has actually fallen into a misunderstanding. These parameters are only superficial, and we need to understand the real needs of users. What is the purpose of a user buying a lamp? What is the original performance of the lamp? After all, their destinations fall on "lighting". Users buy lamps for lighting, and the original performance of lamps is also lighting. Based on this, Road Smart thought deeply and got the answer. Users are not buying parameters, configuration or power, but light. Only the total amount of light and the quality of light actually emitted by solar street lights are our initial requirements for solar street lights. After understanding this demand, we need to understand some industry-related knowledge first Industry knowledge How to judge the light source? 1. Average life: The average life of a light source refers to the time it takes for 50% of the light sources to fail after multiple light sources are turned on at the same time. 2. Strobe: The number of times the light source flashes per second. Failure to provide a stable voltage will cause a large strobe. A light source with a large strobe will cause the most damage to the eyes. 3. Luminous flux: For a lamp, the simplest explanation is the amount of light emitted, the unit is lumens (LM). 4. Luminous efficiency: The luminous efficiency of the lamp is how much light can be emitted per unit power, the unit is LM / W. 5. Rendering index: The degree to which the light source restores the color of the object. Generally speaking, the response of sunlight to the color of objects is the best and the most realistic, so their color rendering is defined as 100, and a color rendering index ≥70 is a good light source. 6. Color temperature: The color temperature of the light source is different, the light color is also different. Light with a low color temperature is yellowish, we call it warm tones, and yellow light has good haze permeability; light with a high color temperature is whiter, and white with high color temperature is used for road lighting. It has intermediate visual effects, good visibility, and brighter than yellow light. After knowing the relevant industrial knowledge, we need to know how to choose the light source. Here are some references for high-power LED light sources. 1. Efficient use of light. Using lamps with patented lenses to improve the utilization of light. 2. Integrated design. The integrated design makes the LED directly connect with the shell, and the heat is radiated through the shell cooling wings and air convection, which fully guarantees the service life of the LED street light. 3. Using street lights with uniform illumination can solve the problems of concentrated light beams and obvious dark spots. So that the illuminated area is larger and the illumination is more uniform. 4. No glare & no strobe. Eliminates visual fatigue and disturbance of sight caused by glare of normal street lights to improve driving safety; 5. Green and environment friendly. Does not contain pollution elements and cause no pollution to the environment; After knowing the principle of light emission, we need to determine the needs. At present, the solar LED street light market is chaotic. Many users and suppliers stay on the previous configuration and power, but with the advancement of technology, we need to redefine light sources. We can clearly find that 10 years ago, the countrysides used 100W light bulbs illuminated the room. Later, we used 30W-40W energy-saving lamps to illuminate the room. And finally developed to LED light sources. A 5W -15W LED light can illuminate the entire room, even brighter. Light bulbs of different powers provide the same brightness, but light bulbs with lower power are brighter and more energy efficient. What is the reason? The same power, different light effects, different brightness The higher the light effect, the brighter. The brightness of a lamp cannot be simply measured by power, but by the luminous flux. Regardless of power, brightness, configuration, etc., it will eventually return to how much light it emits. Only the light that this lamp really emits is our ultimate demand. According to this demand, Road Smart pioneered the RS standard, which judges and tests the light by the total amount of light radiation and the quality of light The development of the industry requires standards, and with standards, the industry can develop in a standardized way. In the future, the Road Smart will continue to work hard to lead the solar lighting industry to intelligent and standardized development and promote the clean and green development of global energy.

These lights are convenient and practical additions that will make everything from using a home security cam to unlocking your door at night a little bit easier. They can also help to keep the critters away from your prized tomatoes. A flood light is designed to flood an area with light. It's very straightforward. Flood lights are most important for outdoor applications. Inside, you have your walls, mirrors, and surfaces of your furniture to help bounce light around to fill the space. One bulb can take you a long way in a small room. Outside, you do not have that luxury. It's a vast expanse, and without a well defined space to contain a light, it sort of leaks out everywhere. A normal light outside wo not go very far. Since a flood light is designed to beam a high concentration of light directly out into a wide area, they will do a better job at illuminating a vast expanse. Flood lights are used to illuminate outdoor concerts and sporting events at night. These flood lights are a lot more powerful than the kind you would need to illuminate your home, since your back porch is substantially smaller than a football stadium. Flood lights for home use are compact, easy to use and install, and relatively inexpensive. Boundery's LumiGuard Pro is an ultra-bright 270 degree motion sensing floodlight. It's the perfect one size fits all solution for some security and safe illumination.

It's the perfect replacement for battery powered LED flood lights, providing substantially more life without the hassle and waste of constantly replacing batteries. Why Do I Need a Flood Light? There are a lot of excellent reasons to add a few flood lights to the front and back of your house. You can position them wherever you need them to make your life a little easier at night. After work, you stop off to have dinner with a friend and run some errands. You make a last minute trip to the grocery store so you can meal prep some healthy meals for the upcoming week. Before you know it, you are getting home at 8 PM. The porch light is not on. You now have the troublesome task of figuring out how to get your groceries to the door that you cannot see to unlock. It's a huge pain, and you are kicking yourself for forgetting to leave a light on. A motion activated flood light solves that problem. As you approach the flood light, it will turn on. You can hold your groceries in one hand and unlock the door with the other because it's easy to see what you are doing. Need to run back out to the car to grab that 12 pack of seltzer? The light will kick back on. If you are having people over for a night time gathering, you probably have a well lit gazebo or porch area. But what happens when someone needs to walk to their car or around the house? They are probably unfamiliar with where they are going, and you do not want them to trip and fall. Solar flood lights and Boundery's Solar LED Stair Lights can make it safe for people wandering around in the dark. People with bad intentions do not want to be spotted. If anyone were casing your house to vandalize or burglarize it, they certainly do not want to do so with a bright spotlight shining directly at them. Mischievous teenagers are programmed to run the moment a light kicks on. It will give them the sense that someone saw them, or that someone could easily see them if they noticed the light kicked on and looked out the window. Strategically placing motion sensor lights near security cameras will help them capture clearer footage. If your camera's night vision leaves much to be desired, keep it in its normal mode and back it up with some solar flood lights. If you live in a quiet area or have a small patch of woods behind your home, you probably love the view. What you do not love is the curious deer and raccoons that want to see what kinds of plants are growing on your property. Rabbits are just as interested in finding snacks at dusk as they are at dawn. If you are growing fragrant herbs, fruits, or vegetables in your backyard, put up a solar light. Any curious animals looking to steal a bite will be scared off when the light kicks on. Motion sensor lights work by detecting infrared waves. People, animals, and cars emit heat. This heat energy can be seen by a motion detector light, especially when it's moving. The sensor picks up on the heat signature that passes before it and, in response, turns on the light. Motion sensing lights can sometimes be triggered by things like foliage aggressively blowing in the wind. If this is a dealbreaker for you, just trim the bushes. You can also adjust the placement of your lights to avoid pointing them directly at greenery. Why Are Solar Lights Better Than Electric Lights? Solar lights are better than electric lights for countless reasons. The most obvious reason is that they do not ever cost you anything to run. They use the light from the sun to charge an internal battery. When the sun goes down, solar flood lights know that it's dark and will automatically begin to work. You never have to remember to plug them in, turn them on, or recharge them. Since they do not require an active source of electricity, you can place them anywhere. You do not need to run wires or extension cords or create hazards to power your solar lights. Anyone can install them with simple instructions and basic tools. How Many Solar Flood Lights Do I Need? The amount of solar flood lights you need depends on what you are trying to achieve. You may only want two: one for the front door, and one for the back door. If you tend to take the trash out at night, it may help to strategically place one by the cans. If you are using them for home security, you will want them near every entrance and exit of your home. You might want to place them near your security cameras or, as a precaution, near any areas of your home that get particularly dark at night. If you entertain on your property, you might want to place them in a way that they will illuminate the way to the nearest entrance of your home. It's polite to help people find the bathroom during a bonfire or late night whiskey tasting. Solar flood lights can be affixed to your exterior walls with screws. They have a place for those screws to go in the form of a built-in mount. It's usually as simple as using the right drill with the right bit to prepare the wall and affixing the light. It is not much different from hanging a mirror or a picture frame. Your solar flood light will come with detailed instructions. Every home can do with a few solar powered LED flood lights. They are a one-time investment for a lifetime of convenience, safety, and peace of mind. It's liberating not to worry about turning the lights off and on when you need them, and it's even better when the light wo not add a single penny to your electric bill. Solar powered LED lights are ready to go right out of the box, and even the laziest DIYer can have them up and ready in time to eat a sandwich and take a nap. It's such a simple fix for a common problem that now you know how easy it is, we are not sure how you will want to go without it!
Outdoor Landscape Lighting - What Are My Options?
As a proud home or business owner you have many reasons to supply outdoor lighting around your property. By illuminating the exterior portion of your home or business you are sending a subtle signal to strangers that your property is occupied and secure.

Primarily, you have a choice in the type of lighting you select and in many cases you can use a combination of both. For a bright constant glow you may choose low-voltage electrical landscape lighting. Although these lights are brighter they also come with a cost as monthly electrical bills will be impacted by this style of lighting. Furthermore, installing an electrical landscape lighting system is more complicated, requires various components, and offers less flexibility when comparable outside solar garden lights. The low voltage systems also depend upon an external electrical source.No such complications exist with outdoor solar garden lights, the other primary style of landscape lighting for homeowners to consider. True, the intensity of a driveway solar light is not as bright as their low voltage counterpart, however cost of ownership, installation, and durability are superior to low-voltage electrical systems. Outdoor solar garden lights can be easily installed anywhere exposure to direct sunlight is available. Once a location is selected, solar garden lights also can be relocated with ease by simply removing the mount and reinserting into another location.In many cases driveway solar lights and other solar powered pathway lights are mounted onto a ground stake that's easily tapped into the ground. The driveway solar light fixture is then mounted on top of the stake and secured with a twist or snapping mechanism. Other outdoor solar lights can be mounted directly on top of the ground along curbing, on steps and stairs, and on other solid structures such as fences or posts. Typically, all mounting hardware for these various applications are included with the light fixture.Low voltage systems reduce the electrical current from 120 volts to 12 volts by utilizing a transformer. Obviously this system requires external electrical access and the need to dig a trench about 3 or 4 inches deep to bury the electrical cable mounted to the lights and connecting to the transformer. The 12-volt system costs also must include not only the light fixtures but also the transformer and electrical cable. In addition to longer installation periods for this system, a homeowner also must consider other issues like potential voltage drops for lights installed furthest from the transmitter. There's less flexibility with electrical systems as the lights usually need to be installed in line allowing for the connection of the power cable between lights.Certainly low voltage systems do emit a consistent light throughout the night whereas solar powered outdoor landscape lights reduce in intensity throughout the night and are least bright as the sun rises. However, a homeowner needs to consider all options before installing a lighting system. Solar lights offer a softer glow but they continue to be a very suitable outdoor lighting option. When considering ease of installation, overall cost of ownership, environmental benefits, and flexibility to the homeowner, solar landscape lighting offers many significant advantages.
