The Home Cinema 2150 beat its 2,500 lumen claim by 117 lumens, measuring in at 2,617 in Dynamic Mode. All measurements were taken at mid-zoom, on Normal power. Not surprisingly, the other modes came in lower. Bright Cinema, which is a great mode to use during the day when you’ve got some ambient light, measured at 1,763. The other two modes, which both have great color, didn’t come in much behind that. Natural mode has 1,708 lumens, while Cinema has 1,690. Not bad.
I found that Bright Cinema was usable with the curtains open, but since we have blackout curtains installed, we preferred to shut them. The other modes are still pretty bright, so we generally just used Cinema mode all the time and it was fine. When switched to ECO mode, Dynamic measured at 1,599 lumens.
