Ushio 1000472 Halogen Projector Lamp

This Ushio halogen bulb is built for projection equipment that requires a 120 V 420 W double-ended lamp. It uses an R7s recessed single-contact base and a CC-8 filament to deliver a bright white output at 3200K colour temperature. The rated life is 75 hours, making it suitable for occasional or event-driven use rather than continuous daily operation.

Thermal output and power draw in normal use

At 420 W the lamp converts most input power into heat, so the fixture must provide adequate ventilation around the quartz envelope. The halogen cycle keeps the filament clean during its 75-hour life, maintaining consistent brightness without noticeable dimming. No active cooling is included; the housing or projector chassis handles heat dissipation.

Integration requirements and space considerations

The R7s base fits standard double-ended sockets found in many projector housings and stage-lighting fixtures. Its compact linear form leaves room for reflectors or lenses directly adjacent to the lamp. Buyers needing longer service intervals or lower heat load should consider alternative lamp technologies not covered by this model.

Questions about this item

How is the R7s recessed single-contact base installed, and what step do people often miss?

Slide each end of the double-ended lamp firmly into the spring-loaded R7s sockets until the contacts seat fully; the step often missed is avoiding bare-hand contact with the quartz envelope, because skin oils create hot spots that shorten the 75-hour life.

What maintenance or replacement will this 420 W halogen lamp need later?

The lamp itself is the only replaceable part; after roughly 75 hours at 120 V the filament fails, so keep a spare Ushio 1000472 on hand and swap the whole bulb when output drops.

What limit appears first during sustained use of this 3200 K halogen bulb?

The 75-hour rated filament life is the first hard limit; continuous operation at 420 W will reach that point quickly, after which the lamp must be replaced.
