But about the projector .... I really _want_ to get the new JVC DLA-RS1 1080p (ready to pull trigger on powerbuy) to enjoy 1080p quality with similar viewing characteristics to the G15 (smoothness, shadow detail, colors). This setup will also probably last us 4-5 years, lots of viewing.
My concern is about light output. The room is a library, two small windows on the right, door on the left, usually quite dark ... but a) late summer sun gives some light leaks on the right, and b) my wife likes to do projects with a small lo-voltage light which casts ambient onto the floor and cabinets. These provide some washout of color and shadows (blacks turn to mid-gray) with my present G15-Greyhawk combo, which reduces enjoyment a lot (for me).
A fellow AVS-er on the PJ forum sent me this: at 700 lumens spec with the grayhawk screen you'd only get 14ftL with a new bulb, and within the first several hundred hours that would likely drop in half to about 7ftL. That is doable IF YOU HAVE TOTAL LIGHT CONTROL but even then depends on your tastes. If you had the Firehawk with a gain closer to 1.3 (as opposed to Grayhawk gain of 0.95) then you'd at least have 20ftL to start and 10ftL after the bulb aged. That still may be challenging without total light control.
So ..... with the JVC RS1 and my existing greyhawk, will this light situation be improved .... worse .... or about the same?
I could live with similar brightness and shadow detail, but would really like more "pop" to accompany the move to 1080p, for the psychological impact of viewing the new media. And I don't really wanna wait a year for the next round of brighter 1080p projectors (at potentially higher prices).
All advice and viewpoints are welcome, in this important, long-term choice for us.
Thanks in advance.
