Just measurred the light output ( a new meter - dont know how precise it is - but its not a expensive model ) with about 1000 hours on the projector ( 1100 ) and with a about real 0.9 gain screen I have in 1.78:1 mode ( 81" wide ) 29 fL in low and 41 fL in high and when in 2.40:1 mode ( 110" wide ) I have 18 fL in low and 26 fL in high on the screen.
I normally only use the low mode ( but not because its to brigth, but to save lamp hours and lower the noise and I dont need
the extra light ).
So typical I look at 18 - 29 fL and I dont find it even close to too bright and if put in high mode, it is still not
even close to "blinding" IMO
Nobody who has ever seen it at my place, has said it was too bright ! ( and my HT is completly
BTW. this is meassured at 100 % ( 235 / contrast at 88 ) and it is not
clipping before 108% ( 251 ).
And a other funny thing is, I have had a CRT projector in the "old days" in the same Black room, and it probely had 3-6 fL on screen, that time I didnt think it was dim
- its strange and impressive, how we adjust to light.
But I could ( or want ) never go back now, to have less then minimum 15 - 20 fL on screen.
