Optoma EX7155e OEM Replacement Lamp

The Optoma EX7155e is a 280W OEM replacement lamp module designed for Optoma projectors. It arrives as a fully assembled bulb and housing unit ready for direct installation. This new lamp uses an Osram UHP bulb rated for 2,000 hours of operation. It serves owners needing a factory-specification light source to restore original brightness.

Practical Limits of UHP Lamp Technology

UHP lamps gradually lose brightness over their 2,000 hour rated lifespan rather than failing suddenly. The 280W power draw requires the projector's original ballast and cooling system to function correctly. Performance depends on the projector's built-in power management and thermal design. Users should expect diminishing light output as the lamp approaches its rated end of life.

Replaces Worn Original Lamp Modules

This module replaces a dimmed or expired original lamp inside compatible Optoma projectors. The jump is worth it when image brightness has dropped below usable levels for presentations or video. It restores the projector to its factory light output specification. Buyers whose projectors require a different wattage or bulb type cannot use this 280W module.

Questions about this item

Which EX7155e lamp version should I pick: OEM Osram, OEM Optoma, alternative OEM or compatible?

The OEM Osram unit uses the original bulb maker's 280W lamp; the OEM Optoma version is the same module under the projector brand; the alternative OEM swaps to a different major bulb supplier; the compatible uses genuine OEM parts at lower cost. All meet ISO9001 checks for ignition, voltage and 2,000-hour run-time.

What does the 2,000-hour rating mean for daily use?

At typical brightness the 280W UHP lamp is rated for 2,000 hours before replacement; that equals roughly four hours every day for over a year or eight hours daily for about six months before brightness drops to half.

Does the lamp housing match the projector's electrical interface exactly?

Yes, the fully assembled module includes the correct connector and housing for the EX7155e, so the 280W Osram bulb seats without adapters and the projector's power supply drives it at the specified wattage.
