yes, I do have a Rigel Systems 'Skylite'. it has two pairs of leds, two on at any one time. mine is a pair of white, and a pair of red leds. it works off a nine volt battery. The dimmer wheel, infinitely variable, is the on-off switch. the led pair is chosen by separate switch. I don't think it would work very long under the sea, rather porous design, fine for the cockpit though...I guess..
