Dell 468-8978 Replacement Lamp

The Dell 468-8978O is a new replacement projector lamp module that includes a fully assembled bulb and housing for straightforward installation. It is designed for users who need to restore brightness to a compatible Dell DLP projector. This accessory arrives ready to fit without additional assembly.

Suitable for DLP projector owners

This lamp suits owners of Dell DLP projectors that accept the 468-8978 module and want a direct replacement with 3000 hour typical life or 4000 hour economy mode. It is not for users whose projectors require a different lamp code or a different power rating. Buyers needing a lamp for LCD or laser light engines should look elsewhere.

185 W lamp power decides fit

The single specification that determines compatibility is the 185 W lamp power combined with the 468-8978 model designation. Only projectors engineered for this exact wattage and form factor will operate correctly and achieve the rated 3000 hour typical lifespan. Verify the projector service manual lists this precise lamp model before purchase.

Questions about this item

Which Dell projector models accept the 468-8978 lamp module?

The 468-8978 lamp fits Dell projectors that specify this part number; check your projector's service manual or the label inside the lamp door to confirm compatibility before ordering.

Will the 185 W lamp run in my older Dell projector that used a lower-wattage module?

Only install the 468-8978 in projectors that list this exact part; using it in a unit designed for a different wattage can cause overheating or startup failure.

How do I verify the new lamp is operating correctly after installation?

Reset the lamp-hour counter in the projector menu, then confirm the image is bright and stable and that the counter begins tracking from zero during normal use.
