It can be confusing trying to find the proper BenQ CS.59J0Y.1B1 lamp for your BenQ PB6240 projector. The Internet has been flooded with companies offering “compatible” generic lamps at bargain prices. These are NOT authentic lamps and should be avoided.

Authentic lamps are important

Your BenQ PB6240 projector is a sophisticated machine with sensitive electronic components. The BenQ CS.59J0Y.1B1 projector lamp has been designed specifically to keep your projector operating at optimum levels. Generic “compatible” lamps are made with copycat technology that use inferior and often toxic materials.
Knock-off manufacturers don’t possess the proper technology to create these lamps and as a result these lamps have a shorter lamp life, are prone to explosions and can seriously damage your projector. 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.
The few dollars you save with generic “compatible” lamps is not worth it in the long run. Save yourself unnecessary headaches and buy a BenQ CS.59J0Y.1B1 lamp from a recognized dealer. You’ll be getting a far superior product with a replacement guarantee and tech support.
