Water enters the showerhead through the flow restrictor

(1) then travels through the injector plate
(2) which directs the water to the waterwheel
(3). The water spins the magnetic waterwheel past the stator
(4) of the field winding
(5). This hydroelectric generator develops the 2.5 volts at .31 amps which lights the PR-6 bulb.

A unique new showerhead that lights up your shower... fun and relaxation for the whole family.

And it's safe! ShowerStar™ generates light through water power so there's no batteries or outside electrical source.
