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 Sylvania, 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 purchases replacement lamp modules, called Diamond Lamps, from a distributor that has a unique set of agreements with these original lamp manufacturers to buy their lamps (bulbs) directly, and to fit them into cages for sale in the replacement market.
Diamond lamps offer value without compromise. The manufacturer original lamp (the identical lamp in the projector when it was new) is mounted inside a new, high quality cage.
Diamond lamp modules virtually replicate the original optical performance and expected life of the lamp module that came with the new projector.
ProLampSales sells only 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. The initial savings is almost always lost in much shorter lamp life and poor optical performance because of lower light output.
