Waterproof marine incandescent bulb at 12 V and 100 W with a nominal diameter of 110 mm (4″). This optical reflector bulb is intended as a spare bulb for marine searchlights, navigation lights, and spreader lights.
The bulb features a vacuum-sealed construction and a silver-plated reflector. The vacuum protects the reflector from oxidation and helps preserve its reflective properties in the demanding maritime environment. The design is waterproof, but no specific IP rating is documented.
This variant has a standard front without the fluted design found on select variants in the same product family. Voltage, power, and diameter must always be checked against the existing fixture before replacement.
The bulb is documented as a spare bulb for the Utility searchlights with item nos. 13.246.02 for flush mounting, 13.248.02 with an adjustable wall bracket, and 13.247.02 with a windshield bracket. It can also be used as a spare bulb in compatible marine searchlights and spreader lights with the correct electrical and physical specifications.
