A few comments,
Too bad for us that Jason has moved on - I really enjoyed working with him, he sold me my close-out RS1.
Bulb data points on my RS1:
I pulled my first bulb at 750 hours so that I would have a spare.
The replacement bulb (also from Jason), just started flickering when it hit 1500 hours. I bumped it to high mode, have like new brightness and a stable picture. I wonder how many add;l hours I will run on high mode before it dies off?
(Did I say - I love this PJ, feeling no urgency for an upgrade)
