Ready-to-install lamp module

This ViewSonic PRJ-RLC-011 replacement lamp arrives as a complete assembly with the Ushio UHB 275W bulb already seated in its housing. It is designed for owners of compatible ViewSonic projectors who need a straightforward, tool-free swap when the original lamp reaches end of life. The module eliminates the handling of a bare bulb and reduces the risk of misalignment during installation.

275 watt UHB lamp constraints

The lamp draws 275W and is rated for 2,000 hours of operation under normal use. Brightness will gradually decline as the hour counter approaches this limit, and the projector will eventually require another replacement to maintain usable image quality. The 275W power level also means the projector’s cooling system must be clean and unobstructed to avoid premature ageing or thermal shutdown.

2,000 hour service window

At typical daily viewing of a few hours the lamp provides months of reliable service before output drops noticeably. Heavy users running the projector for extended sessions each day will reach the rated lifespan sooner and should plan for a spare module. The fixed 2,000 hour rating means the lamp cannot be refreshed or extended; once the rated hours are exhausted a new module is the only way to restore full brightness.

Questions about this item

Which of the four versions of the ViewSonic PRJ-RLC-011 should I choose for my projector?

Three are OEM lamps from the original bulb maker, ViewSonic or another OEM supplier, all built to ISO 9001 quality checks; the fourth is a lower-cost compatible using genuine OEM parts.

What does the 2,000-hour lamp life mean once the lamp is installed in my projector?

It is the rated operating time before brightness drops to roughly half its initial output, based on standard test conditions at 275 W.

What interface or standard governs the 275 W rating and what does it cap in practice?

The 275 W rating defines the electrical power the lamp draws; the projector's ballast regulates ignition voltage and running current to stay within that limit.
