ABSTRACT:
An underwater light includes a high intensity lamp placed in an enclosure that allows for easy lamp replacement in case of breakage or natural failure. Electrical wires are soldered to a metal fitting on the lamp. The metal fitting is received in a plastic nipple and the space between the fitting and nipple is filled with a sealant, leaving the ends of the wires exposed. The wires are connected by water proof twist-on wire connectors and the end of the lamp is enclosed by a rubber boot and an end cap. When the lamp burns out, it is easily replaced by fishing the light out of the water, removing the rubber boot to expose the twist-on wire connectors. The twist-on wire connectors are removed and the old lamp discarded. A new lamp is installed in reverse order.
