I have the sony 45es now which is rated 1800 peak lumens, and in low power mode it is quite bright on my gray screen. Since I got used to this level of brightness my concern is will 1500 lumens suffice, especially in low power mode (which I prefer because it reduces the fan noise which is another of my concern). Measured lumens in projector central review is showing average of 800 lumens in low power for the 270es and about 850 for the 45es. So will the 50 lumens make a big difference? My max budget is 4-4.5 lac, so not considering JVC or higher sony models for now which are all above 5.5.1500 lumens is quite less, my optoma hd25 claims 2500lumens, but that too is peak momentary brightness and even at 2500 rated, i find it to be barely passable. Your milage may vary.
Would request anyone who owned or seen the 270 to chime in please. Need to get a user based understanding of the brightness rather than some review.
Cheers,
Sid
