Repay / LED product design


Why waste light as an energy source? This bulb makes use of its own daytime light to recharge itself for night time use. The light given off from the central LED light charges the solar panels in the upper portion of the bulb and stores it for use in its LED night light. This environmentally friendly product makes a light bulb not only as a passive light source but also as an active electricity-storage system to power itself as a night-light.
