Avtech’s lighting fixtures have been standard equipment aboard the C17 aircraft since the programs inception. Recently, the same design has been applied to the USAF C-5 upgrade program. The fixtures are designed to operate over the -40 to +71 degree C temperature range and are able to withstand 9 G’s of random vibration and meet all other environmental requirements typical of a military or commercial freighter/cargo application.
Integrated within the fixture are two electronic ballasts which use 115 VAC, 400 Hz power. The ballast also boasts a 20:1 dimming capability. The fixtures use four T10 lamps and supply up to 160 watts of fluorescent lighting power per fixture.
Both overhead and sidewall fixtures are used in the aircraft, with critical engineering demands put on the equipment due to the severe service typical of military cargo transport missions.
