Davis Megalight Replacement Bulb

Multi-volt (10-30VDC) BA9S bulb for those looking for something brighter than the typical 5W incandescent found in many boat lamps such as the Aqua Signal Series 15, Series 20, Portofino, Toronto, and Palma types.

9mm single-contact base with 12 super high-efficacy 3014 type LEDs arrayed in 360° around the bulb, giving a true isotropic output. The output of this lamp rivals that of a 10W incandescent (100 lumens) - much brighter than the typical 5W incandescent while fitting in even the smallest fixtures.

This BA9S LED lamp replaces the Davis Megalight bulb, Aqua Signal 90282, 90247, 90496, and 90384 bulbs. It also replaces Hella part numbers BYL125, BHL126X, BHL124, and BHL244 bulbs. If using in Series 20 Sidelight type Navigation Lights, choose red/green respectively to maximize light output and visibility through colored lenses.

Note: The Aqua Signal 90470 (20W) high output bulb found in Aqua Signal Combination Masthead/Foredeck Lights requires our BA 9S 5W LED bulb.
