BenQ SW921 370W replacement lamp

The BenQ SW921 is a 370 watt NSH projector lamp module rated for 2000 hours of operation. It arrives as a fully assembled bulb and housing unit, ready for direct installation without separate component handling. This genuine OEM replacement suits owners of compatible BenQ projectors who need a factory-specification light source. Buyers who want a bare bulb without housing or a lower-wattage alternative will not find that configuration here.

Thermals noise and power draw

The lamp consumes 370 watts during normal projection, so the projector's cooling system must handle that thermal load. Acoustic output depends on the host projector's fan design rather than the lamp itself. The 2000-hour rating reflects standard operating conditions defined by the manufacturer. No independent noise or temperature measurements are supplied for this module alone.

ISO9001 quality checks and version choice

Each unit undergoes ISO9001 quality checks covering beam performance, ignition, voltage, appearance, connections and run-time. Depending on stock, the module may come from the original bulb manufacturer, the BenQ-sourced OEM, another OEM bulb maker or a compatible third-party build using genuine OEM parts. The supplier provides a 90-day warranty and 30-day return window on every version. Free ground shipping is included with purchase.

Questions about this item

How do I install the SW921 lamp module and what step is often missed?

The SW921 arrives as a complete housing with the NSH 370W bulb pre-assembled. Power off the projector, let it cool fully, remove the old module, insert the new one until it seats firmly, then reset the lamp timer in the menu — skipping the timer reset is the step most people forget.

What maintenance or replacement will the SW921 need later?

The NSH 370W bulb is rated for 2,000 hours of use. Once that limit is reached the lamp module must be replaced again; no user-serviceable parts or cleaning intervals are specified for the housing itself.

What limit appears first during sustained use of the SW921?

The rated 2,000-hour lamp life is the primary limit; after those hours the NSH 370W bulb reaches end of life and the module requires replacement.
