Generating electricity from Tube lights for charging battery operated electronic items using Led's

We all know that Light Emitting Diode will act as a good light source but it can also act as a good light absorber that meant a light detector. The project based on the concept of generating the electricity from the light energy that has been emitted by the house-hold lamps. This has been used to generate electricity from lights at Houses and this saved electricity can be used to charge up battery operated devices. We can implement this system in many place where the large number of Tube lights has been used.
