Replacement lamp for Optoma projectors

The Optoma 5811100173 is a new projector lamp module that includes a 280W Osram UHP bulb pre-mounted in its housing. It is built for owners of compatible Optoma projectors who need a direct, ready-to-install replacement without separate bulb handling.

Consistent output over the rated lifespan

The 280W UHP lamp is engineered to maintain stable brightness and colour performance across its 2,000-hour service life. Manufacturing to ISO9001 standards includes run-time and ignition testing so the lamp delivers reliable operation from first strike to end of rated hours.

280W UHP bulb with 2,000-hour rating

The single specification that determines fit is the 280W UHP bulb rated for 2,000 hours; projectors requiring a different wattage or lamp life will not accept this module. Buyers whose units call for an alternative power rating or longer rated life should verify the part number before ordering.
