Airfield Halogen Bulb 40 W

This halogen lamp delivers 40 watts at 6.6 amps and is built for airfield lighting installations. Its multifaceted reflector and female flat-connector leads suit runway, taxiway and approach fixtures. The unit is FAA-approved for use with many OEM fittings and rated for up to 1500 operating hours. It provides consistent, dimmable output across fluctuating temperatures and vibration.

Female Flat Connector Base

The cable flat female base is the single specification that determines fit; it matches the socket used in numerous airfield lighting series including cross-references 64333A, 6110 and 58301. Buyers whose fixtures require a different base type such as a screw or pin terminal cannot use this lamp.

Thermal Behaviour in Service

Halogen operation at 40 watts produces noticeable heat at the reflector and leads, so fixtures must tolerate elevated temperatures. The design is engineered for reliable output in severe weather and vibration without flicker. No cooling fan or active thermal management is included; heat dissipates through the fixture housing.
