The Dr. LED AR111 / PAR36 sealed-beam LED bulb (PN 9000074) is a waterproof LED replacement for compatible halogen AR111 and PAR36 sealed-beam lamps. It provides 700+ lumens of cool-white (~6000K) output from U.S. Cree® LEDs while drawing far less power than a typical 50W halogen sealed beam.
Designed for nominal 12V and 24V DC systems (10–30VDC) as well as 12VAC applications, it is suited to selected Aqua Signal Series 41 masthead/foredeck lights and compatible Perko sealed-beam fixtures.
