I installed a new "K" lamp in my HT1000 this week. I had changed to normal with the old lamp for several months but at1500 hours the brightness was down to 9.5 FtL using the normal setting on my 80" Da Lite screen.
The new "K" lamp is results are different from the previous lamp at 1500 hours.
Here are the results for my calibration.
Please note that these results are with my system on my screen in my dark room with light yellow walls and a white ceiling. I did not super tweak since the lamp wil lbe changing a lot in the next 100 hours. The results below did get to 6500 degrees +/- 50 degrees or so with DVI and RGB.

Partially on your recommendation I also have the Da-lite deluxe insta-theater 80" screen in my living room and I also have the new bulb and have noticed the brightness difference.
I had read that the difference was subtle between the original bulb and the new one, but I find it to be significant. I notice the difference so much that I have kind of become a brightness junkie! The new bulb makes me want to run the projector in the full mode rather than eco because, particularly with high def material, the brightness is incredible. My old bulb was nearly dead but I had sent my projector in for repairs and in changing the board, NEC lost my bulb life settings. I love the new bulb.
Do you have the specs for how long the "K" lamp should last.
It would be possible to tell the NEC that there was a new lamp at 1500 hours for example if the new lamp supposed to last 3000 hours instead of 2000 and then run it for another 1500 hours before changing.
