Common questions
Will this lamp fit a Hitachi CP-X5W?
Yes, part 78-6969-9946-1 covers the Hitachi CP-X5W along with the CP-X264, CP-X3, CP-X3W, CP-X5, CP-X6 and CP-X6W, plus the 3M WX20, Dukane Image Pro 8783 and three Viewsonic projectors.
What other codes match this lamp?
456-8783, DT00821 and RLC-039 are alternative references for the same lamp sold as 78-6969-9946-1. Any of these on your old unit's sticker confirms this is the right replacement part.
Does 78-6969-9946-1 install as one sealed unit, housing and all?
It does. This is the module type, so the bulb arrives already seated in its housing and cage and goes into the projector as one piece, with no bulb transfer into an old housing required.
How long should this lamp last?
It carries a 2000-hour rating at the stated 190W. Actual hours depend on how much the projector is used in eco mode versus full brightness, and on ventilation around the unit.
What should I check before ordering?
Confirm your projector model against the sixteen listed here, spanning 3M, Dukane, Hitachi and Viewsonic, and check whether your existing lamp is a module or a bare bulb before buying, since the two are not interchangeable.
