Just popping in to comment on the new lamp again for this year's models. It seems to be really, really good. Can fluctuate up to 10 or so center, peak lux during course of watching for several hours, but it seems to reach its brightest points after several hours on. I have 8.5' wide 16x9 screen. At less than 1 hour, for that size screen, on low lamp with the projector about 2/3 of the way back to long throw, I got 180 for the reading. I am just hitting 190 hours with a calibration thrown in as well at 100 hours. Just measured a little while ago the highest reading I have seen in about a week...... 179.6 lux. Dayam!! That is unlike any lamp I have ever owned. It just keeps chugging along with extremely low brightness loss.
