ABSTRACT:
An underwater light has a head assembly including a reflector, a light source located in the head assembly and movable relative to the reflector, a housing that moves relative to a slide that engages the switch such that it is twist activated. Continued twisting adjusts the position of the light source to adjust beam spread. Bearings are included in the head assembly to allow the twisting action to be effected under high pressure, while o-ring seals prevent leakage.
