This waterproof incandescent bulb is a sealed 24 V DC, 50 W Sealed Beam replacement bulb for marine searchlights, navigation lights, and spreader lights. The bulb has a nominal diameter of Ø110 mm, equivalent to 4 inches, and features a fluted front lens for spreader lighting.
The Sealed Beam construction integrates the light source, reflector, and front lens into a sealed unit. This makes the bulb suitable as a replacement light source for compatible marine fixtures where a waterproof Ø110 mm bulb with the correct voltage and wattage is required. No specific IP rating is documented.
The fluted, prismatic front lens is designed to distribute light in spreader lights and other compatible searchlight fixtures. The bulb is used in applications including spreader searchlights, recessed hull and side spotlights, platform lights, and recessed stern lights.
Documented compatibility includes fixtures with item nos. 13.243.91, 13.243.93, 13.258.24, 13.256.24, 13.257.24, and 13.259.24. Always check the fixture's voltage, wattage, and bulb diameter before replacement, as other variants in the product family have different electrical data and dimensions.
