It can be confusing trying to find the proper BenQ 59.J9301.CG1 lamp for your BenQ PB2140 projector. The Internet has been flooded with companies offering “compatible” generic lamps at bargain prices. These are NOT authentic lamps and should be avoided.

Installing them cancels your warranty leaving your vulnerable should anything go wrong. It’s not worth the small savings.  Protect yourself from buying a knock-off counterfeit compatible generic lamp.
