Step 2: Be ready with an authentic projector lamp
Keep your BenQ MX761 projector working at its optimum levels by always using an authentic BenQ 5J.J3J05.001 projector lamp for your BenQ MX761 projector. Generic lamps may promise to work just as well but they don’t and end up costing you more money in the end.
6 reasons to go with authentic projector lamps:
- generics have shorter lamp life than original lamps
- generics are created with toxic materials including carcinogenic Krypton-85
- generics are prone to explosions
- generics are incompatible and damage the sensitive optics in your projectors
- no guarantee or refunds – you’re on your own with no technical support or refunds
