What this lamp replaces

The GreenTechLLC NP21LP is a 330 W compatible projector lamp that replaces the original NEC NP21LP module. It fits a wide range of NEC PA series models including the PA500U, PA500X, PA550W, PA550WG, PA5520W and PA600X families. The lamp ships new in a compatible housing with the bulb pre-installed.

When to install a new lamp

Swap the lamp when the projector warns of end-of-life or when brightness drops below usable levels. The unit is rated for 1,500 hours in normal mode and up to 3,000 hours in economy mode, so the upgrade is worth it once the original module reaches those limits.

Check your projector model first

Verify the exact model number on your NEC projector against the compatibility list before ordering. This lamp is not suitable for projectors outside the listed PA series or for users who require an original NEC manufactured module.

Questions about this item

What projector models does the NP21LP 330 W lamp fit?

The lamp fits NEC PA500U, PA500X, PA550W, PA550WG, PA5520W and PA600X series projectors, including the NP-PA500UJL, NP-PA500XJL13ZL, NP-PA550WJL, NP-PA550WJL13ZL and NP-PA600XJL variants.

How do I install the NP21LP lamp and what step is often missed?

Power off and cool the projector, remove the lamp cover screw, pull the old module by its handle, insert the new NP21LP module until it clicks, replace the cover screw, then reset the lamp timer in the projector menu — the timer reset is the step most often forgotten.

When will the NP21LP lamp need replacement and how is it rated?

The lamp is rated for 1500 hours in normal mode and 3000 hours in economy mode; replace it when brightness drops noticeably or the projector displays a lamp-warning message.
