Ushio 750w 77v QXL Halogen Bulb - ETC Source Four Revolution replacement lamp

Ushio QXL 750W/77V, tungsten halogen, medium to high voltage, single-ended
Ushio’s QXL (Quick eXchange Lamp) Halogen lamp, was designed in conjunction with ETC’s new Source Four Revolution automated spotlight.
The QXL utilizes the proven performance characteristics of the 750 watt HPL with increased lumen output.
The patented QXL base is revolutionary in that it allows the user to quickly change the lamp with out opening the fixture. This feature eliminates any issues with lamp alignment and optical settings.
Because overheating is a common adversary with Halogen lamps, USHIO has developed new Heat-Shield technology that prevents seal failure due to high thermal radiation generated from the Halogen capsule. This ensures that 300 rated life hours will be achieved.
