Ushio HPL-575/120X+ halogen lamp

The Ushio HPL-575/120X+ is a 575W 120V tungsten halogen lamp built for professional stage and studio fixtures. It delivers 12360 lumens at a 3050K colour temperature with a CRI of 100. The T6 clear bulb measures 4.09 inches in overall length and 0.72 inches in diameter. Rated life is 2000 hours in new condition.

G9.5 two-pin base with heat sink

The single specification that determines fit is the G9.5 two-pin base with integrated heat sink. This base matches fixtures designed for the HPL lamp family and ensures proper electrical contact and thermal transfer. Without this exact base type the lamp will not seat or operate safely in the intended socket.

Designed for ETC Source Four fixtures

The ultra-compact 4-C8 filament geometry raises fixture lumen output by up to 20 percent compared with earlier HPL designs. It requires a 120V supply and a fixture rated for 575W halogen lamps with a G9.5 socket. The lamp frees up headroom in lighting plots by delivering more output from the same instrument without increasing power draw.
