Wow 2K USD is low, compared to the € price I was given by the Benq Europe marketing director at ISE. The WXGA Shorth Throw unit is clearly aimed at the education/classroom market, and that market receives serious discounts, but the list prices for those projectors are generally very high. I was told it will start to arrive at the end of Q2 i.e. June. And will cost €3000,-. And he agreed that for the classroom it needed to be run in normal mode. And now I see they use 50% brightness as end of life time. Very uncommon for LED projectors, wich dropp off 5-10% over the 20-50K hours life specified. 10K hours in eco mode and the output is allready down to 61%.
Presuming the same drop-off rate in normal mode, it will be at 1200 lumens after just 5K hours.
I overheared the Viewsonic will also be 3000. They kept standing in front of the small screen, discussing 'too much. People buy between 2000 and 3000. But the colors, look at the colors', if they don't want you to hear they should step aside, a show is to show;-). So image looked not too bright, but colors rich and picture not washed out.
The Qumis were showing a very tiny image. Guess they realize it only offers 40 percent of the specified 300 lumens. Eatmeat the Chinese measured 118 lumens didn't they, 120 lumens is only 40% of 300 lumens;-).
Have you heared about the LG 600? 600 specced lumens.
