Ready-to-install lamp module

The DataStor ELPLP77 lamp module arrives fully assembled with a new 280W UHE bulb inside its housing. It is built for the Epson PowerLite 1975W projector and replaces the original lamp without extra parts or tools. The unit is supplied new and manufactured to ISO 9001 quality standards.

Verify projector model before ordering

Confirm that your projector is the PowerLite 1975W so the ELPLP77 housing aligns with the lamp compartment and connector. The module is not universal; other Epson models use different housings or wattages. Check the existing lamp label for the ELPLP77 code to avoid a mismatch.

Rated life under continuous use

In normal mode the lamp is rated for 4,000 hours and in economy mode for 5,000 hours before brightness drops below usable levels. Sustained operation in normal mode produces the full 280W output and reaches the shorter rating, while economy mode reduces power and extends the interval. Actual hours depend on cycle frequency and ventilation.

Questions about this item

Does the lamp arrive as a complete module or must I buy a separate housing?

The lamp ships as a fully assembled module with the 280W UHE bulb already installed in its housing, so no extra housing purchase is needed.

Which version should I choose among the OEM and compatible options?

All four versions — three OEM variants and one compatible — meet ISO9001 standards and are tested for beam performance, ignition, voltage and run-time.

What does the 4,000-hour normal rating mean for daily use?

In normal mode the lamp is rated for 4,000 hours; at four hours per day that equals roughly two and a half years before replacement is recommended.
