Direct replacement lamp for Optoma EW531

This 185W projector lamp module ships fully assembled with bulb and housing for immediate installation. It matches the original part number SP.8EH01GC01 and is built to ISO 9001 quality standards. The unit is supplied new and ready for use in compatible Optoma projectors.

Two selectable modes extend usable life

Normal operation yields 2000 hours of lamp life while Economy mode stretches that to 3000 hours. The 185W UHP bulb maintains consistent output across the rated span rather than fading quickly after a short burst. This dual-rating design lets users balance brightness against replacement frequency.

185W UHP bulb defines compatibility

The lamp draws 185 watts and uses a Philips UHP light source, so the projector must support that exact wattage and bulb type. Installing it in a unit rated for a different power level will cause errors or damage. Buyers who need a different wattage or a bare bulb without housing should look elsewhere.

Questions about this item

How hot does the 185W bulb run during all-day projection?

The 185W UHP bulb generates significant heat; the projector's internal cooling fans must run continuously to keep temperatures within safe limits.

Does the lamp module include the housing so I only need the projector itself?

Yes, the module arrives as a fully assembled 185W bulb inside its housing, ready for direct installation into the compatible Optoma projector.

Will this SP.8EH01GC01 lamp work in my older Optoma projector that originally used a lower-wattage module?

This lamp is built for the EW531 series; using it in a projector designed for a different wattage or housing can cause fitment or thermal issues.
