Abstract
A shower lamp assembly is formed with a water driven electric generator to power an LED light source. The assembly includes a first channel directing water to drive the generator. The generator is supported on a movable portion of a bypass valve that opens on a high water flow condition to direct a portion of the water to a second channel way from the generator. The generator is otherwise tuned to provide sufficient electricity under low water flow conditions to properly power the lamp. The lamp generator is then protected by the bypass valve from damage during high water flow conditions.
