Review on 🔦 CTLAMP NP21LP Projector Replacement Lamp with Housing - Compatible with NEC NP-PA500U PA500X PA550W PA600X by Troy Boren

This was perfect for my NEC NP-PA600X projector. The housing looked the same as the OEM bulb I removed, except for the brown electrical connector instead of the black one. The location of the lamp and its wiring inside the case looked the same. I don't have a luminosity meter so I can't say if this lamp is really as bright as the original when it was new. But it was certainly a huge improvement over the 3 year old incandescent bulb. Although the old lightbulb did not burn out, its output was quickly dimmed due to the reflective metal coating inside the lightbulb. So quality wise I am very happy with this bulb and at a good price for this bulb I plan to order a few more to put on the shelf as spares for the future.
