Genuine 185 W replacement lamp for BenQ MP512 ST

This new projector lamp module combines a Philips UHP 185 W bulb with a complete housing, arriving fully assembled for immediate installation. It restores original brightness and colour accuracy to compatible BenQ projectors without requiring additional tools or alignment steps. The unit is manufactured to ISO 9001 quality standards and tested for beam performance, ignition voltage and run-time consistency.

Verify the exact projector model before ordering

Confirm that your device is the BenQ MP512 ST and that the manufacturer part number 9E.Y1301.001 matches the label on your existing lamp module. Different revisions or regional variants may use a different housing or connector, so cross-referencing the part number prevents fitment issues. The product is supplied as a direct OEM replacement and is not intended for other projector series or third-party housings.

Rated 3 000 hours in normal mode

The 185 W UHP bulb delivers stable output with predictable thermal behaviour when the projector’s stock cooling system is clean and unobstructed. Economy mode reduces power draw and extends lamp life while lowering acoustic noise from the cooling fans. Regular filter maintenance helps sustain these rated lifespans and prevents premature brightness decay.

Questions about this item

What comes with the 9E.Y1301.001 lamp and do I need any extra parts?

The module ships as a complete 185 W bulb inside its housing, so it fits straight into the projector without additional components.

How do the OEM and compatible versions of the MP512 ST differ?

Three OEM variants use bulbs from Philips, Osram, Ushio, Phoenix, Iwasaki or Matsushita; the compatible version uses genuine OEM parts from a leading third-party maker. All meet ISO 9001 checks.

What does the 3 000 to 4 000 hour rating mean for daily use?

In normal mode the lamp lasts about 3 000 hours; switching to economy mode extends it to roughly 4 000 hours before replacement is needed.
