Genuine replacement lamp for Optoma projectors

The Optoma 5811100173 module supplies a new 280W UHP bulb pre-fitted in its housing, so the unit is ready to install without extra assembly. It suits owners of compatible Optoma projectors who need a direct, factory-specification light source.

Assembled housing simplifies installation

The bulb-and-housing assembly removes the handling of a bare lamp, reducing the risk of contamination or misalignment during a change. Manufacturing follows ISO 9001 checks covering beam performance, ignition, voltage, connections and run-time.

Rated 2,000 hours at 280W

The lamp delivers a quoted life of 2,000 hours under standard operating conditions; heavy daily use will reach that limit sooner than occasional sessions. Buyers who need longer intervals between replacements or a lower-wattage alternative will not find those options in this module.
