Genuine Replacement Lamp Module

This DataStor projector lamp is a complete module with a new 280W UHE bulb installed in its housing. It arrives ready for direct installation in the compatible Epson Powerlite projector without additional assembly. The unit is manufactured to ISO9001 standards using OEM components for reliable operation. Buyers receive a new lamp module tested for beam performance and run-time.

For Maintenance of Specific Epson Projectors

This lamp suits owners of an Epson Powerlite 4770W projector requiring a genuine compatible replacement to restore original brightness. It is not for users of different projector models or brands, as the housing and connector are model-specific. Buyers needing a bare bulb without the housing or a higher-wattage alternative should look elsewhere.

Rated 280W UHE With Dual-Mode Lamp Life

The lamp operates at 280 watts using UHE technology and delivers a rated life of 4,000 hours in Normal mode or 5,000 hours in Economy mode. This single specification determines whether the replacement matches the projector's designed power draw and expected maintenance interval. Verify the model number ELPLP77 against the projector manual before ordering.

Questions about this item

How much heat and power does the 280W UHE lamp generate during all-day use?

The lamp draws 280 watts and produces heat proportional to that power; the projector's internal cooling system manages temperature during extended operation.

Which Epson projector models accept the ELPLP77 lamp module for installation?

This replacement module is built for the Epson PowerLite 4770W projector and fits the lamp compartment designed for the ELPLP77 part number.

Will the 4,000-hour normal life rating still apply if I keep using my existing ceiling mount and cables?

Yes, lamp life is determined by the 280W UHE bulb and internal ballast, not by external mounting hardware or signal cables.
