Genuine 280W Replacement Lamp

Lamp Life by Operating Mode

In normal mode the rated lamp life is 3000 hours, while economy mode extends the rating to 4000 hours. Actual runtime will vary with usage patterns, ambient temperature and the projector's power management settings.

Replaces Worn Original Modules

This lamp replaces a dimmed or failed original module and restores factory brightness and colour performance. The upgrade is worthwhile when the existing lamp has reached its rated hours or when image quality drops below acceptable levels for presentations or home viewing.

Questions about this item

Which version of the EX779 lamp should I choose among the OEM, OEM-compatible and third-party compatible options?

Three OEM versions are available — direct from the original bulb maker, the same lamp sold by Optoma, and an alternative OEM bulb — plus a lower-cost compatible module built with genuine OEM parts; all are manufactured to ISO 9001 standards and tested for beam performance, ignition, voltage, connections and run-time.

What does the 280 W rating mean for brightness and heat in my projector?

The 280 W P-VIP bulb delivers the same power draw and light output the projector was designed for, so image brightness matches the original specification and the cooling system handles the heat exactly as it did with the factory lamp.

How long will the lamp last in Normal versus Economy mode?

Rated life is 3,000 hours in Normal mode and 4,000 hours in Economy mode, giving a clear expectation for replacement planning.
