The confusion may be that they feel the perceived brightness of the current units is close to 1000 lumens.
Sorry, in the dome at ISE, I saw the black billboard next to the unit 100000 hours of lifetime on the projector (so not just the LEDs wich Luminus indeed claimed upto 100,000 hours, depending on implementation), and 1000 ANSI lumens. And that was not the first time I saw official DPI material claiming 1000 ANSI Lumens. I have commented on it at the time, as all the DELTA based units were doing something in the 400-500 lumens at the time. And I noted how it was not (or barely) bright enough for the small screensize used in the demo.
Perceived brightness, hmm, I always noted how lacking the brightness of LED projectors was. Delta, PD, and even the Sim2 50. The 150 was a bit better, but even in the dark room on a Black Diamond screen with some gain the Mico 150 did not look particular bright, this year, Personally I would have used a slightly smaller screen, the concertmaterial shown was a bit dark to begin with, so at they they did not choose the easyest demomaterial;-). Runco was showing the dual unit that was looking brighter, but that was on a gain 2 screen. The Runco ultrashort throw LED unit (LS100?) was in the regular LED range, so fairly dim on that 90 (100?) inch diagonal screen. Perceived brightness on LED projectors has never been something I have been cheering about. The first time I saw a PD LED the green was indeed quite saturated, but that did not lead to it looking bright, and it was demoed on a tiny tiny screen. The other first generation units have never impressed in brightness. The only one I thought was brighter than expected was the 70" 1080P Cube from Planar I saw a year and a half ago, Planar claimed 700 lumens.Edited by donaldk - 7/13/12 at 3:20pm
