Compatible projector lamp module

This replacement lamp and housing is built for the Vivitek D873ST projector. It arrives as a complete module so installation does not require separate bulb handling. The unit is supplied new with a 90 day warranty. It suits education or business users who need a direct swap for a depleted lamp.

Typical thermal and power profile

The lamp operates within the thermal envelope designed for the D873ST chassis. Fan noise and power draw remain consistent with the projector’s original specification. No additional cooling or electrical provision is required beyond the host unit.

Sustained operation characteristics

Under continuous use the module maintains stable output for the duration of its rated life. Brightness decay follows the standard curve for genuine AL Series lamps. The 90 day warranty covers premature failure during extended running.

Questions about this item

How do I install the D873ST-LAMP-A lamp module in my Vivitek D873ST projector and what step is most often missed?

Power off and unplug the projector, let it cool completely, remove the lamp cover, loosen the retaining screws, slide out the old module, insert the new D873ST-LAMP-A housing until it seats firmly, tighten the screws, replace the cover, then reset the lamp timer in the menu — the step most often missed is resetting the timer.

What maintenance or replacement will the D873ST-LAMP-A need after extended use?

The lamp brightness will gradually decline; when the image becomes too dim or the projector indicates end of life, replace the entire D873ST-LAMP-A module — no separate filter or bulb-only change is required for this housing design.

What limit appears first on the D873ST-LAMP-A during sustained operation?

The lamp reaches its rated lifespan and brightness drops below usable levels before any other component in the housing fails.
