Claim:
1. A diving light for underwater photography, comprising: a housing or body containing a battery and electronics, the body being sealed against intrusion of water, a face plate of heat-conducting metal on the front of the housing or body, the face plate facing forward, comprising contiguous metal and including an LED light source positioned to project through a window in the face plate, the LED light source being mounted on an LED mounting plate directly secured against said contiguous metal of the face plate and in thermal conductive contact with said contiguous metal of the face plate, the contiguous metal of the face plate being positioned to be in direct contact with water around the front of the diving light such that heat from the LED light source is conducted from the LED mounting plate into the contiguous metal of the face plate and directly into the water at an exterior of the face plate, the face plate being configured such that water can enter the diving light between the body and said contiguous metal of the face plate to contact a back side of said contiguous metal of the face plate to cool the LED light source from a back side of the LED light source, and a water-sealed switch on the exterior of the housing or body, connected to selectively power the LED light source, at desired light levels, whereby cooling of the LED light source is effected by contact of water with the face plate at an exterior front of the diving light and also at the back side of the face plate.
