We want you to have the best experience possible with your InFocus projector, and using lamps that aren’t authentic can do bad stuff to it. We don’t want that. You don’t want that. So we take extra care to make sure every InFocus Certified Lamp gives you the best performance and value possible. 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 usage Not 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
