Hitachi's CP-RX70 family and 3M's CL20X and X20 share this complete lamp module with Dukane's Image Pro 8770 and Viewsonic's PJ355 and PJ358. Hitachi also lists it against the CP-X1, CP-X2, CP-X253, CP-X4, CPX1J, ED-X20, ED-X22, HCP-60X, HCP-70X, HCP-75X, HCP-76X, MP-J1 and MP-J1EF, for twenty-one compatible projectors in all.
This module is rated at 160 watts for 2000 hours, and the identical lamp appears under 78-6969-9903-2, DT00781 and RLC-027. As a complete module, it fits straight into place, so if your old lamp shows any of these numbers, or your projector matches one of the twenty-one models above, this is the right part.

Common questions
Which Hitachi CP-X models take the 456-8770 lamp?
CP-X1, CP-X2, CP-X253, CP-X4 and CPX1J all use this module, alongside the CP-RX70, CP-RX70W and CP-RX70WF, and the ED-X20, ED-X22, HCP-60X, HCP-70X, HCP-75X, HCP-76X, MP-J1 and MP-J1EF.
What does DT00781 refer to?
DT00781 is another code for this same lamp, along with 78-6969-9903-2 and RLC-027. If your existing lamp shows one of these numbers rather than 456-8770, this is still the correct match.
Does this listing include the housing?
Yes, it is a complete module with the 160-watt lamp fitted in place, rated for 2000 hours. It installs directly without needing to transfer the bulb from your old unit.
How do I reset the lamp counter after replacing it?
Most Hitachi and Viewsonic projectors have a lamp-hour reset in their service or setup menu, which resets the on-screen usage warning once a new module has been fitted. Check your specific model's manual for the exact steps.
What should I check before I order?
Confirm your projector matches one of the twenty-one listed models, or that the code on your existing lamp matches 456-8770, 78-6969-9903-2, DT00781 or RLC-027, before placing your order.
This is a complete module — bulb already seated in its housing, so it drops straight in.
