As a bare lamp, 78-6969-9464-5 reuses your projector's existing housing rather than replacing it. It covers the 3M MP8649, MP8748 and MP8749, the Boxlight CP-635i, Dukane's Image Pro 8052 and 8801, and a wide Hitachi CP-S370 to CP-X385W range, plus two Liesegang models and four Viewsonic PJ750 and PJ751 projectors. It is rated at 200W for 2000 hours.
The same lamp is also sold as the module 456-227, with the bulb pre-fitted into a new housing, so choose that version instead if your projector's housing needs replacing too. Other codes for this lamp include DT00431, PRJ-RLC-001 and ZU0286044010. As no photograph exists for this part, rely on the part number and fitment list to confirm the match.
