-   -   700 lumens enough for grayhawk? (http://www.avsforum.com/forum/23-screens/19597-700-lumens-enough-grayhawk.html)

700 lumens, no ambient light. Is this enough for the grayhawks .95 gain?

My problem is that within the next year or so, I plan on getting a new projector, but I'm moving into a new house and have a room dedicated to home theater, so I want to buy a fixed screen. I want to get a stewart and was thinking the Studiotek, but all I've heard are great things about the Grayhawk.

Any suggestions, comments?

It's really going to be a matter of size. If you want to get a 9 or 10 foot wide screen, it is not going to be enough. However, if you stick with a 6 or 7 foot wide, you should be okay. I highly recommend the grayhawk for any digital projector.

Depending upon the size of the screen and how close you really are to
700 lumens, it can be enough.

You could always put up a Greyhawk and shrink the image til it's bright
enough for you. Any replacement projector in the next couple of years
will probably be brighter. I use a calibrated G1000 which by most accounts
probably has 750 lumen (with a new bulb) on a 16:9 8' wide Grayhawk.
I'm awaiting my Panamorph lens which should give me a fine image since
it will give me about 30% more light due to the full use of the 4:3
panel. 750 lumen / (8' x 4.5') = 20.8 lumen/sq.ft. (with Panamorph)
and it's probably about 15 lumen/sq.ft. without.

How would I be able to tell if its 700 or not (btw, I have a brand new bulb)? Also, the screen size I was thinking is 92x52. Any more comments?

Thanks for all your help,
