Ushio 1000540 Halogen Projector Bulb
The Ushio 1000540 is a 300 watt halogen lamp built for projector applications that demand accurate colour. Its 3200K output and CRI of 100 suit photography, film or stage lighting where faithful rendering matters. The 7800 lumen rating provides strong output for its class. Buyers needing longer run times or cooler operation should consider alternative technologies.
GY 9.5 Prefocus Base and Compact T6 Envelope
A GY 9.5 two pin prefocus base ensures precise alignment in compatible sockets without tools. The T6 tubular envelope measures 3.55 inches overall, allowing fitment in tight projector housings where larger lamps cannot sit. A clear finish transmits maximum light without diffusion. Fixtures requiring a different base type or longer envelope cannot accept this lamp.
200 Hour Life at 120 Volts
Rated life is 200 hours at the full 300 watt, 120 volt supply, so frequent replacement is expected in heavy use. The C-13 filament runs hot, meaning the fixture must handle significant heat and ventilation. Noise is limited to any cooling fan in the housing, as the lamp itself is silent. Power draw remains a steady 300 watts during operation.

Questions about this item
What does the GY 9.5 2-pin Prefocus base mean for compatibility?
The GY 9.5 base has two pins spaced 9.5 mm apart and a prefocus collar that locks the filament position; it only fits sockets made for that exact base type.
Will the 3.55-inch overall length fit inside my fixture?
The lamp is 3.55 inches long end to end; measure the socket-to-lens distance in your fixture to confirm there is enough clearance.
How do I install the bulb without shortening its 200-hour life?
Wear clean gloves, align the two pins with the socket slots, push straight in until the prefocus collar seats, and avoid touching the quartz envelope with bare fingers.
