Replacement lamp for NEC, Dell.

This Philips DLP replacement lamp uses the original 9281-678-05390 UHP bulb and fits models such as the NEC NP-PX800X, Dell 7700 and Barco RLM-W12. It is supplied as a bare bulb only, without a housing, for direct installation in compatible projectors. The lamp is new and covered by a 180-day warranty.

Dual-power 400W and 320W operation under sustained

The lamp is rated for both 400W and 320W modes, allowing the projector to select the appropriate power level for brightness or economy settings. During extended presentations the UHP bulb maintains stable output without the rapid decay seen in short-burst testing. The 1.3 A current draw remains consistent across the operating range.

Interface limited to projectors using

Compatibility is restricted to projectors that list the 9281-678-05390 part number, including the Acer P7205 and Titan 1080p series. Units requiring a different lamp code or a complete module with housing cannot use this bulb-only part. Buyers needing a pre-assembled lamp assembly or a different wattage class should look elsewhere.

Questions about this item

Will the 400W/320W 1.3 AC lamp run hotter or louder than the original module in my NEC NP-PX800X?

The bare UHP bulb replaces the original 9281-678-05390 part directly, so thermal output and fan noise stay at the projector's designed levels.

Do I need the existing lamp housing and ballast to install this bulb-only unit?

Yes — this is a bare E21.9 400W/320W 1.3 AC bulb, so you must reuse the original housing and the projector's own ballast.

Can the 9281-678-05390 bulb work in a Dell 7700 projector that currently uses a different lamp code?

The 9281-678-05390 bulb is listed for the Dell 7700, Acer P7205, Barco RLM-W12 and all NEC NP-PX models shown, so it fits those older units without modification.
