Claim:
1. An LED light assembly for retrofitting an incandescent light fixture for use under water, the incandescent light fixture having a housing with a base, the LED light assembly comprising; a shaft including a top threaded portion and a lower threaded portion, the lower threaded portion configured to screw into the base to provide electrical power to the LED light assembly; an LED adapter including circuitry for a plurality of LEDs, the LED adapter in electrical communication with the lower threaded portion of the shaft; a circuit board including the phurality of LEDs, the plurality of LEDs in electrical communication with the LED adapter; a thermally conductive disc including a thermally conductive path for conducting heat from the circuit board to the housing, the thermally conductive path including at least a top surface of the thermally conductive disc engaging the circuit board and an outer surface of the thermally conductive disc configured to engage the housing, wherein the top threaded portion of the shaft extends through the thermally conductive disc; and a nut in threaded engagement with the top threaded portion of the shaft, wherein tightening the nut forces the thermally conductive disc toward the base and forces the outer surface of the thermally conductive disc into tighter engagement with the housing.
