ViewSonic PRO 8400 Replacement Lamp

The ViewSonic PRO 8400 OEM replacement lamp module delivers a 280W P-VIP bulb pre-installed in its housing for immediate installation. It is designed for users whose ViewSonic projector requires the RLC-059 module and who want a genuine Osram light source without separate bulb handling.

Lamp Life and Usage Constraints

Rated life reaches 4,000 hours in normal mode and 6,000 hours in economy mode, so brightness will gradually decline within those windows. The fixed 280W power draw means the projector’s cooling and power supply must already support this wattage; no adjustment is possible on the module itself.

280W Osram P-VIP Bulb Specification

The single deciding factor is the 280W Osram P-VIP bulb inside the assembled housing; if your projector calls for a different wattage or bulb type this module will not operate correctly. Buyers who need a different power rating or a bare bulb without housing should look elsewhere.

Questions about this item

Which PRO 8400 lamp version should I choose among the OEM and compatible options?

Three OEM versions exist: the original bulb maker's lamp, the ViewSonic-sold OEM lamp, and an alternative OEM bulb manufacturer's lamp. A lower-cost compatible version using genuine OEM parts is also available. All meet ISO9001 standards and pass beam, ignition, voltage and run-time checks.

What does the 280W rating mean for brightness and heat in my projector?

The 280W P-VIP bulb delivers the light output the PRO 8400 was designed for. Expect the same brightness as the original lamp and similar thermal load, so the projector's existing cooling handles it without modification.

How do the 4,000-hour normal and 6,000-hour economy ratings translate to real use?

In normal mode the lamp is rated for 4,000 hours; switching to economy mode extends the rating to 6,000 hours by reducing power and brightness. Actual life varies with usage patterns, power cycles and ambient temperature.
