This bare lamp is built mainly for Hitachi's CP-X880, CP-X885 and CP-HX5000 models, along with the Hitachi SRP-3240, 3M's EP8790LK and MP8790, Dukane's Image Pro 8711, Liesegang's dv500, Proxima's DP-8400 and the Viewsonic PJ1250. It runs at 275 watts with a 2,000-hour rating.
You may also see this bulb listed as 456-238, DT00531, PRJ-RLC-005 or ZU0289044010, all naming the same part. As a bare lamp it needs an existing housing in working order, so inspect your current cage and lens for cracks or looseness before fitting the replacement bulb.

Common questions
What is the difference between PRJ-RLC-005 and 78-6969-9601-2?
None functionally, they are the same bare lamp under two different catalogue codes. PRJ-RLC-005 also appears alongside 456-238, DT00531 and ZU0289044010 in older listings for this identical bulb.
Does this lamp fit the Hitachi CP-HX5000?
Yes, the CP-HX5000 is listed alongside the CP-X880, CP-X885 and SRP-3240 as compatible with this bare lamp. All four share the same lamp compartment design from this generation of Hitachi projector.
Is a housing included with this lamp?
No, this is a bare bulb only. You fit it into the housing that is already inside your Hitachi, 3M, Dukane, Liesegang, Proxima or Viewsonic projector rather than replacing the cage itself.
How do I reset the lamp hours after replacing the bulb?
Open the projector's on-screen menu, find the lamp or maintenance settings, and choose to reset the hour counter. Doing this after every bulb change keeps future warnings based on the new lamp rather than the old one.
What warning signs suggest the 78-6969-9601-2 is nearing the end of its life?
Dimmer brightness, a shift in colour tone, or an on-screen warning as use approaches the 2,000-hour rating are the usual signs. Replacing the bulb at that stage avoids it failing without notice during use.
This is a bare lamp — the bulb only. You reuse the housing already fitted in your projector.
