Solar security lights are a new take on an old need: security. For many home and business owners; a security light is more than a luxury, it is a necessary deterrent to vandalism and theft.  The drain a security light places on the power grid is one of the most significant yet least talked about things in the conservation movement.
If you switch from a traditional version to solar security lights eliminates the power draw while maintaining the equivalent security blanket that a normal light would provide. Depending on the style of light you choose, you may not even need to run any wiring.
Motion sensor lights can acquire enough energy during the day from a built in panel in most cases. This is because motion sensor lights don’t stay on the entire night, they simply switch on when the sensor detects movement. The sensor itself requires a very minimal amount of power, especially when  compared the amount required for a high illumination light bulb.
