Compatible Vivitek projector lamp

This 230 W DLP replacement lamp and housing fits Vivitek ActivBoard-178, D850, D856STPB, D857WT, PRM32 and PRM35 models. It is a new aftermarket module built to match the original 5811116781-S part code. The unit weighs 0.99 kg and ships as a single complete assembly. A 90-day warranty covers the lamp.

Suitable for education and meeting rooms

Classrooms and boardrooms running the listed Vivitek projectors can restore full brightness with this direct-fit lamp. Environments that need longer run times between changes should note the 2,500-hour rating at full power. Buyers whose projectors are not in the compatibility list must choose a different part.

Rated hours and operating headroom

Full-power operation delivers 2,500 hours before replacement is due. Switching to Eco mode extends the interval to 4,000 hours, reducing both power draw and heat output. Heavy daily use at maximum brightness will reach the limit sooner; occasional Eco-mode sessions push the change interval further out.
