Ready-to-install lamp module

The ViewSonic PA501S replacement lamp arrives as a complete 190 W bulb-and-housing assembly that matches the original RLC-111 specification. It is intended for owners of compatible ViewSonic projectors who need a direct drop-in part without separate bulb handling.

Rated life varies by mode

In standard operation the lamp is rated for 4500 hours, while economic mode extends the rating to 15000 hours. Actual runtime will depend on usage patterns, ambient temperature and how often the projector is power-cycled, so the figures represent design targets rather than guaranteed minimums.

OEM-grade build with ISO 9001 checks

Each unit is assembled from genuine Philips, Osram, Ushio, Phoenix, Iwasaki or Matsushita bulbs and undergoes checks for beam performance, ignition voltage, connections and run-time. The pre-fitted housing ensures correct alignment on installation, but buyers who require a bare bulb for custom housings or who need a different wattage should look elsewhere.

Questions about this item

Which version of the PA501S lamp should I choose among the OEM and compatible options?

The listing offers three OEM versions — direct from the original bulb maker, the ViewSonic-branded unit, or an alternative OEM source — plus a lower-cost compatible module built with genuine OEM parts; all are fully assembled with housing for direct installation.

What does the 190 W rating mean for brightness and heat in my projector?

The 190 W bulb delivers the light output the PA501S was designed for; running at this wattage matches the original brightness and thermal profile, so the projector’s cooling and colour performance stay as specified.

How does the lamp connector interface with the PA501S and what does it limit?

The module uses the exact factory plug and housing keying for the PA501S, so it seats securely and the projector’s power supply governs the 190 W draw — no adapter or firmware change is required.
