Power Night Lights with Solar Cells
Some night lights are needed in areas such as bathrooms that have windows to charge batteries during
the day. Placing such a night light in a window area can provide a night light for someone going to the
bathroom in the middle of the night. The night light would have a solar cell on the back and a white LED
source on the front. It could be stuck to the window with double sided sticky tape or held by a suction
cup. Would it use less power if it were activated by the presence of infrared?
