Direct replacement lamp for ViewSonic PX747-4K

The RLC-117 module delivers a complete bulb-and-housing assembly rated at 310 watts. It is built for owners of the PX747-4K projector who need a ready-to-fit replacement without separate bulb handling.

Pre-assembled housing simplifies the swap

Because the bulb ships already seated in its cage, installation only requires opening the projector lamp door and sliding the unit into place. The main risk is touching the glass envelope with bare fingers, which can create hot spots and shorten life.

Rated for 4000 hours at full power

In standard mode the lamp provides 4000 hours of operation before brightness drops to half. Switching the projector to economic mode extends the cycle to 15000 hours, reducing thermal stress during long sessions.

Questions about this item

How can I confirm the 310W lamp is operating correctly after installation?

The projector should display a bright, stable image with no flickering; the lamp-hour counter will reset to zero and begin counting toward the 4000-hour standard rating.

What components are included and is anything else required for installation?

The module arrives as a complete RLC-117 housing with the 310W bulb pre-assembled, so no additional parts or tools are needed for fitting.

Which version of the PX747-4K lamp should I select for my projector?

All four versions — three OEM variants and one compatible — are built to ISO9001 standards and fit the PX747-4K; choose based on whether you prefer the original bulb maker, ViewSonic-branded OEM, an alternate OEM source, or the value compatible option.
