1. how do solar lights work?
Solar lights collect energy using a small solar panel, also called a photovoltaic cell or a solar cell. These cells are made of a semi-conductor, which is usually silicon. Semi-conductors are materials which are sub-metallic, and under certain conditions, will act like a metal and allow current to flow. When light of certain wavelengths strikes the electrons around an atom in a solar cell, the electron becomes excited and gains enough energy to break away from the atom and "jump into the conduction band". When this happens, it leave a "hole" which is filled by another electron, but this electron had to come from somewhere right? This movement of electrons produces a current. In those solar powered garden lights, this current used to charge a battery which will power the light during the night. The light also contains a sensor which will sense when the sun is no longer up, and turn the light on.
2. How long does it take for solar lights to charge?
This entirely depends on the type of and capacity of the batteries, the power of the solar cells, the amount of hours of sunlight available. Further more it will also depend on the actual led(s) in use
3. Solar lights aren't working when my electrical lights are on!!!?
solar lights are set to come on in the dark and the light from your other lights is hitting the sensor (not necessarily on the solar panel)
4. Can solar lights can be used at night on airport runways?
No. They are not bright enough and they dont stay "charged" for long periods of time generally. They are useful in places like cemetaries and on sidewalks and such because they are usually only needed for the dusk and early hours of darkness where airport runways are used all hours
5. What can i do about hispanic neighbour he keeps running over my Outdoor Solar Lights because he keeps cutting?
uhm fighting fire with fire is not good. report him to the authorities. trying to pop his tire will put you in legal jeapordy as well. i would hope you were more mature than that
6. 10 Best Outdoor Solar Spotlights Reviewed (May 2021)
There are several reasons why you should buy solar lights. First, solar lights are environmentally-friendly. They use a renewable energy source, which is sunlight. They cut down the carbon footprint, saving the planet's natural resources. Also, they are a cost-efficient option compared to conventional lights, reducing your overall electricity bills in the long run. They save you installation costs as well because it is easy to set them up without any professional help. They also require little-to-no maintenance, and it is fairly simple to keep your solar lights functional for a long time, proving a convenient choice. The best outdoor solar spotlights from our list are available in several styles, so most people can find an option to suit their aesthetic preference. You can find that they come in different colors and allow easy adjustment, including low and high brightness settings to complement the mood. How to find the best outdoor solar spotlights? To get the best solar-powered outdoor lighting for your garden, you need to go through all the important features carefully. First of all, you need to set a budget range and look for reliable options within that range. After that, you need to consider the space you are looking to illuminate to estimate how many of them you need and how bright the solar lights should be. For this purpose, considering features like the number of LEDs, the output and brightness of the lights, and the available colors are important. To find the best outdoor solar-powered LED spotlights, you can refer to the buying guide below. How many lights to buy? You need to carefully consider the outdoor space that you want to illuminate because it helps you determine how many lights you will require to light up space as brightly as you want. For larger spaces like the pool area or a garden, you need more than 2 pieces, so the ROSHWEY Outdoor Solar Spotlights can be an ideal option. At the same time, for the porch or the steps, even two lights are enough. Their performance also depends on the number of LEDs each piece has and the brightness and output of those LEDs. If your solar lights are bright, you will need fewer of them. Number of LEDs in each spotlight The number of LEDs translates directly to how bright each spotlight will be and shows the overall lumen output. This is an important consideration because it determines how dimly or brightly lit your exterior space will be. If you need a dimly lit cozy space, fewer LEDs will work perfectly. Considering the number of LEDs in a single light also has relevance to where you want to use them. Larger spaces require powerful lights. Therefore, you will need more LEDs in a single spotlight. For example, the DBF Outdoor Solar Lights offers 18 of them in each spotlight. If the spotlights have only one or two LEDs, the output will be limited, and you will have to buy more pieces to light up your exterior space. Solar spotlights are available in different colors and variations. They can include bright white light, blue-tinted shades, a warm white glow, yellow light, and other multicolored options. Most of the options on our list let you choose from three different color settings, such as seen with the LITOM 12 LEDs Solar Landscape Spotlights. The color temperature of LEDs is measured in Kelvin. LED bulbs with lower temperature cast a warmer shade of light that is less bright and more soothing. Thus, warm lights like the InnoGear Solar Lights work best for gardens. Higher temperatures give whiter light shades that are sharp and enable high visibility. The height of an outdoor solar-powered spotlight comprises the height of the stake and the height of the light itself. To prevent the spotlights from swaying and falling, you must make sure that the stake is installed in the ground properly. That way, it will withstand harsh winds and rain. The stake should be at least 3 inches under the ground for it to stay stable. The LITOM 12 LEDs Solar Landscape Spotlights with their 8" stakes ensure optimal installation. The light output of a solar spotlight is determined by the power and the number of LEDs used, and it determines how brightly they will be able to glow. Outdoor solar spotlights can have an output range from 100 to 600 lumens. Also, you can also control that if your model comes with brightness adjustment settings, letting you decide how dim or bright you need your spotlights to be. Solar spotlights with up to 600 lumens of light output are perfect for use near houses and for residential purposes. For instance, the Linkind 16 LEDs Solar Landscape Spotlights are the brightest on our list. Next, the output also depends on the battery charge. In cold weather and days with sparse sunlight, the output of your solar lights may be lower. The battery capacity of a solar-powered spotlight is important to consider because it directly translates to the number of hours it will stay lit when fully charged. Apart from that, it also tells you a lot about the quality of the battery of your solar light. The battery capacity is represented in ampere-hour (Ah) or milliampere-hour (mAh) and indicates the amount of energy that the battery can store. A battery model with higher capacity lasts much longer. In our reviews, you can find that these products offer about 8 to 10 hours of runtime, depending on the output and the brightness setting. The premium Itscool Solar Spotlights goes beyond that and stays on for up to 16 hours. This is a crucial feature to consider, especially for outdoor solar lights, since they are subject to all kinds of weather conditions and have to stay functional for a long time even in rainy, windy, and snowy conditions. The weather resistance of an outdoor solar light depends on the materials and construction. It is important to find a solar light with a waterproof rating of at least IP 55. Do note that IP 65 certified solar lights, like the DBF Outdoor Solar Lights, are better and more resistant to water damage. Outdoor solar lights that are constructed with durable and sturdy materials, like ABS plastic, cast aluminum, and stainless steel, can easily withstand harsh weather conditions. The flexibility and adjustability of the solar panel and spotlight are important for them to function properly. The solar panel should be moveable to face the sun directly to it to produce more energy. A fully charged battery will make them able to glow for a long time and keep your exterior spaces lit when it's dark. The solar lights should also be rotatable so that you can change their position even after installation.
