1640 lumens in low lamp, iris closed mode, ugh.
Is there any way to reduce the light output further?
According to Carleton Bale, that would be roughly 60 ft lamberts on a 120" D2.35:1, 1.3 gain screen. That's a tad bright.
Any chance Sim2 might offer this PJ with a 200 or 250 watt UHP bulb? Perhaps in the previous one box solution?
Alan Gouger, last I read your screen is an 8ft wide scope. You must be at at least 50 plus ft lamberts, even with a 1.0 gain screen? You have commented, in this thread, that it is a bit bright for you.
If you use the long end of one of the 3 zooms, you could lose another 20- 30%? Anything else? Aged bulb 20%? Zooming vs anamorphic?
