It’s the cool thing to do.Cool- We test our lamps far beyond industry standards for performance, reliability and safety- Our lamps come with a 6-month or 1-year warranty*- Our lamps are optimized to work with your InFocus projector, often resulting in higher brightness, longer life, and lower power usageNot cool- Non-InFocus lamps can cause damage to your projector’s electronics- Using other lamps will invalidate the projector’s warranty- The quality of non-InFocus lamps is very inconsistent- Non-InFocus lamps don’t last as long – thus, costing you money and time to replace them
