Direct Replacement Lamp

The OPTOMA EX779i projector lamp is a new 280W P-VIP module that ships as a complete bulb-and-housing assembly. It matches the original part number 5811116885 and is designed for owners of compatible Optoma projectors who need a ready-to-install light source without separate bulb handling.

Rated Operating Hours

In normal mode the lamp is rated for 3000 hours of use, while economy mode extends the rating to 4000 hours. Both figures represent the manufacturer’s expected lifespan under continuous operation rather than a brief test period, giving a clear indication of how long the light output should remain stable before replacement is required.

Compatibility Check

Verify that your projector model accepts the EX779i designation and the 5811116885 part number before ordering. The product is offered in several OEM and compatible versions, so confirm which variant your supplier provides if your installation requires a specific bulb manufacturer.
