Genuine ViewSonic RLC-021 lamp module

This replacement lamp module is built for ViewSonic projectors that accept the RLC-021 part. It arrives as a complete bulb-and-housing assembly so technicians can swap it without extra tools. The unit is supplied new and ready for immediate installation.

285 watt NSH bulb specification

The lamp uses a 285W NSH bulb that matches the original power rating for compatible ViewSonic models. This wattage determines brightness output and thermal load, so the projector must be designed for a 285W source. Installing it in a system rated for a different wattage will cause errors or damage.

Pre-assembled housing reduces downtime

Because the bulb is already seated in its housing, the module eliminates the alignment step required by bare-bulb kits. This cuts replacement time and lowers the risk of contaminating the optical path during service. The module is manufactured under ISO 9001 quality controls and backed by a 90-day warranty.

Questions about this item

What does the 285 W rating mean for brightness in my projector?

The 285 W NSH bulb restores the original light output your projector was designed for, so image brightness returns to factory levels.

Which lamp interface does the RLC-021 use, and does it limit compatibility?

The module uses the proprietary ViewSonic DT00771 housing that plugs directly into the projector’s lamp connector; no other interface is involved.

What physical space does the assembled housing need to fit?

The bulb-and-housing unit matches the exact dimensions of the original ViewSonic lamp module, so it slides into the same compartment without modification.
