Replacement lamp for Hitachi and Dukane projectors

This 290‑watt GreenTech lamp fits Hitachi CP‑WU8450, CP‑WU8451, CP‑WUX8450, CP‑WX8255 and CP‑X8160 models as well as Dukane ImagePro 8950W, 8971, 8973W and 8975WU series. It replaces OEM part numbers DT01291, DT01295, SP‑LAMP‑081, 003‑120708‑01 and 456‑8971. The unit ships new in compatible housing with bulb installed.

Fits directly into the projector lamp compartment

No additional adapters or wiring are required; the lamp seats in the existing housing and connects to the projector’s standard power interface. Installation frees the original equipment from a dimming or failed light source and restores full brightness for presentations, signage or classroom use. The compatible housing matches the factory form factor.

Rated 1500 hours in normal mode

Under continuous operation the lamp maintains stable output for the rated period before brightness declines to the replacement threshold. Economy mode extends usable life by reducing power draw while still delivering adequate illumination for typical meeting‑room conditions. Regular filter cleaning helps sustain these intervals.
