Lamp life and power consumption

Rated output is 185W with a quoted lifespan of 2,000 hours in normal mode or 3,000 hours in economy mode. The UHP bulb technology maintains consistent brightness across the rated period. No separate cooling or ballast specifications are provided by the supplier.

Deciding specification — wattage and hour rating

The single figure that determines fit is the 185W rating matched to the EX531-EDU designation. Buyers whose projectors require a different wattage or connector layout cannot use this module. Verify the exact model code before ordering.

Questions about this item

How do I install the EX531-EDU lamp module, and what is the common mistake?

The module arrives as a fully assembled 185W bulb and housing. Power off and cool the projector, remove the old lamp cage, insert the new module until it seats firmly, then secure the screw. The step people miss is resetting the lamp-hour counter in the projector menu after installation.

What maintenance or replacement will this lamp need later?

The UHP lamp is rated for 2000 hours in normal mode or 3000 hours in economy mode. When brightness drops or the projector signals end of life, replace the entire module. No separate filter or bulb-only change is required for this housing design.

What limit appears first during sustained use?

The 185W UHP lamp reaches its rated life of 2000 hours in normal mode or 3000 hours in economy mode before brightness falls below usable levels. Heat buildup in long sessions can also trigger automatic shutdown until the projector cools.
