Compatible replacement lamp for NEC

The GreenTech NP44LP lamp fits a wide range of NEC models including the NP-P474U, NP-P474W, NP-P554U, NP-P554W, NP-P603X and NP-P604X series. It also serves Dukane ImagePro 6647W, 6647WU, 6655W and 6655WU units. This non-OEM module replaces the original NP44LP assembly with a compatible housing and bulb. It is intended for technicians or AV managers restoring brightness to supported projectors.

330 W lamp delivering 1500 hours normal

At 330 watts the lamp provides the rated output for the listed projectors. Normal mode yields approximately 1500 hours of operation before replacement is needed. Switching to economy mode extends the usable life to around 3000 hours while reducing brightness. The lamp is not suitable for projectors requiring a different wattage or housing design.

Thermal and power characteristics in typical use

The 330 watt rating determines the heat load the projector cooling system must handle during normal operation. Fan noise will reflect the projector's own thermal management rather than the lamp itself. Power draw at the mains corresponds to the 330 W lamp rating plus the projector's electronics. No separate cooling or power specifications are provided for the lamp module alone.

Questions about this item

Will the NP44LP lamp fit my NEC NP-P474W without changing the projector housing?

Yes, the NP44LP lamp is designed as a direct replacement for the NP44LP module and fits NEC NP-P474W and other listed models using the original housing.

How can I verify the 330 W lamp is operating correctly after installation?

The projector lamp-hour counter should reset to zero and brightness should reach full output; expected life is 1500 hours in Normal mode or 3000 hours in Economy mode.

Does the NP44LP package include both the bulb and the housing, or must I buy the cage separately?

The unit is supplied as a compatible housing and bulb assembly, so no separate cage purchase is required.
