Light saver! This device was made to save energy of the lights you use in your house. A lot of times people will waste hundreds of dollars of money because they leave their lights on. This device will detect how much light there is, if there’s enough amount of light in the room the lights will turn off. If the light in the room is low enough, the lights will turn on. The “light saver” will save people hundreds of dollars a year. I chose to lower the amount of energy we use in our house because that’s where most people spend their money and I think it would be very helpful.
