Genuine 280W replacement lamp

The Optoma DE.5811100173 module delivers a new 280W UHP bulb inside a complete housing, ready for immediate installation in compatible Optoma projectors. It serves owners who need a direct swap without rewiring or extra tools. Buyers who want higher brightness or a different wattage will need another part.

Lamp life of 2000 to 3000 hours

Rated output lasts 2000 hours in normal mode and extends to 3000 hours when the projector runs in economy mode. This single figure determines whether the lamp matches the usage pattern you expect. If your schedule demands longer continuous cycles, this unit will not meet that need.

Consistent output under sustained use

The lamp is manufactured to ISO9001 standards and tested for beam performance, ignition, voltage and run-time, so brightness remains stable across long sessions. Economy mode reduces power draw to stretch the rated hours further. Installations that run continuously beyond the rated limits will see accelerated degradation.
