Lumens is important if you have ambient light. Less important in a dedicated home theater room. For comparison a candle generates 13 lumens and a 100W light bulb about 1,200.


Here's a nice article describing candlepower, candela, lumens, foot-Lamberts, etc but the short form is the brightness of the projector x shineyness of the screen / size of the screen gives you the final image brightness.

Bigger the screen the brighter the projector or the higher the gain screen to get the same final brightness you desire.


Movie theater is ~16 ftL, RPTVs ~30 ftL, CRTs 40-50 ftL and plasmas 70+


If you want a huge plasma like setup then you want more lumens.

Why the bump? He answered your question well. What more do you need to know?
