Replacement lamp module RLC-091

The OSRAM RLC-091 is a 240W projector lamp and housing unit designed for Viewsonic projectors. It fits models including PJD5483S, PJD6544W, PJD8333s and PJD8633ws. The module delivers original specification brightness and clarity for reliable projection performance.

Original specification housing and connectors

Built with authentic internal components, the lamp assembly matches the manufacturer’s electrical and mechanical design. The 20.8 lamp type and AC 240W power rating ensure consistent output without modification. Direct-fit housing allows straightforward installation in compatible projectors.

Upgrade from older RLC lamp codes

This module replaces earlier lamp and housing codes such as RLC-080, RLC-084, RLC-089 and RLC-090. The jump is worth it when the original lamp reaches end of life or brightness drops below usable levels. Buyers needing a different projector interface or higher wattage should verify compatibility before purchase.

Questions about this item

What projector models does the RLC-091 lamp and housing fit?

The RLC-091 module fits Viewsonic projectors PJD5483S, PJD6544W, PJD8333s, PJD8633ws and replaces part numbers RLC-080, RLC-084, RLC-089 and RLC-090.

What power rating must the projector support for this 240 W lamp?

The lamp is rated at 240 W AC with a 20.8 specification, so the projector must accept a 240 W lamp of this type.

How is the RLC-091 installed and what step is often missed?

Power off and cool the projector, remove the lamp cover, release the retaining screws, slide out the old module, insert the new RLC-091 housing until it seats firmly, re-tighten the screws, replace the cover, then reset the lamp timer in the menu — the timer reset is the step most often forgotten.
