Ready-to-install lamp module

This projector lamp module arrives as a fully assembled 280W UHP bulb inside its housing. It fits Optoma projectors that use the DE.5811100235 part number and is ready to install without additional assembly. Buyers who need a bare bulb for a custom housing cannot use this module.

Simple swap with quality checks

Installation is a straightforward swap of the old module for the new one. Each unit is tested to ISO9001 standards for beam performance, ignition, voltage, connections and run-time before shipping. The housing alignment must match the projector exactly; a mismatched housing will prevent proper seating.

Rated for 2000 hours of use

The lamp is rated for 2000 hours of operation at 280W. Under sustained use the brightness will gradually decline as the UHP bulb ages. Projectors that run continuously for long sessions will reach the rated life sooner than those used intermittently.

Questions about this item

How can I confirm the UHP 280W lamp is performing correctly after installation?

The projector should display a bright, stable image with no flickering or colour shift; the lamp-hour counter will reset and begin counting up from zero toward the rated 2000-hour life.

What components are included and what must be purchased separately?

The module arrives as a fully assembled UHP 280W bulb inside its housing, ready to install; no extra parts are required for replacement.

Which version of the DE.5811100235 lamp should I select?

Four versions are offered: the OEM lamp from the bulb maker, the same lamp sold by Optoma, an alternative OEM-compatible lamp, and an economical compatible lamp built with genuine OEM parts — all manufactured to ISO9001 standards.
