The solar spot light is powered using commercial grade solar cells. It is very easy to install, as you do not have to dig trenches to connect it with your household electricity. Rather, the solar spot light is self-contained, with a small solar cell that stores energy in a rechargeable battery. This solar light is virtually maintenance free and will last many years. It even works under cloudy and overcast conditions. You can place this light in an area with a lower level of sunlight and still get the nighttime lighting that you desire. The light output is equivalent to a 15W light bulb.
