Compare Original vs. Copy Projector Lamps

Projector manufacturers do not make the lamp modules that provide the light output powering their projectors. They buy their lamps from a few established manufacturers. The principal lamp manufacturers who build the lamps that go into most new projectors are: Philips, Osram, Phoenix, Ushio, Iwasaki and Panasonic.

These original lamp manufacturers work closely with projector OEMs to ensure the lamp set-up delivers the optimum performance for specific projectors. Original lamps undergo rigorous testing throughout the manufacturing process to ensure they meet quality and performance standards.

ProLampSales sell two types of replacement lamp modules:

(1) OEM (Original Equipment Manufacturer), the same lamp module (bulb and housing) that shipped with the new projector. OEM lamp modules usually are the most expensive replacement lamp option, giving the buyer 100% confidence that the optical performance will be identical to when the projector was new.

(2) Hybrid lamp modules called Diamond Lamps include a high quality lamp (bulb) manufactured by Osram, Philips, Iwasaki, Ushio, Phoenix or Panasonic that is fitted into a compatible housing. Diamond lamps cost less than OEM and provide a value solution that will provide excellent optical performance.


ProLampSales sells only OEM or Diamond lamps.

For most of our lamps we publish the watts, rated life and the manufacturer of the lamp you will receive.

There are other lamp manufacturing companies and resellers who offer “compatible” or copy lamps at lower prices than Diamond lamps and much lower than OEM lamps. The initial savings is almost always lost in much shorter lamp life and poor optical performance because of lower light output. The best time to buy one of these ultra low cost lamps is when you know you will be replacing your projector within a few months and all you want is a useable lamp module in the interim.
