Sea-Dog 441891-1 12V 20W Halogen Bi-Pin Light Bulb, 700 Candlepower

The Sea-Dog 441891-1 is a 12.8VDC halogen replacement bulb built for marine light fixtures that use a JC-type, bi-pin, G4-style base. It draws 1.66 amps at 20 watts and produces 700 candlepower, giving a bright, focused output suited to interior cabin lights, deck lights, and other small marine fixtures that accept a bi-pin G4 halogen bulb. The bulb has a glass envelope and a compact 1-1/4 inch overall length, keeping it a direct drop-in for fixtures designed around this bulb size and base style.

This is the 20-watt, 700-candlepower version in the Sea-Dog bi-pin bulb lineup; a lower-output 10-watt, 350-candlepower version (441890-1) is also available in the same base style for fixtures that call for less light output. The 441891-1 is sold per pair, so each package supplies two bulbs, and each bulb weighs 0.016 pounds. As a glass halogen bulb, it should be installed and handled the same as any halogen lamp: avoid touching the glass with bare fingers and make sure the fixture is de-energized before installation.
