I have just started My long and drawn out research for my home theater DLP Projector, My only question is Lumens. The question is how are they rated. I figured out bigger is better. but on the low end (800) am I going to have problems with light that's filtered in. if someone could drop a line to help I would appreciate it

Thanks

John

John,

Also remember that lumens are a photometric (your eye is the 'sensor') and not radiometric (an instrument) units. Since your eyes respond logarithmically to light (lumens), twice as many lumens does not appear to be twice as bright to your eyes.

Going from 800, let's say, to 1200 lumens will probably seem brighter, but may not seem as great as the numbers might indicate. HNick
