I also finally figured out how to use my AEMC CA813 light meter and took measurements of my lamp at 4000 hours (RS400, 108" 1.78:1 measured, 136" 2.35:1 screen):

And, yes, I also got one of those spare lamps from Dominic, so we're really on the same page here.
I may even follow your example and take a reading of my lamp...
Anyway, I think that I'm caught up now. Mainly I wanted to know the significance of the "Lamp Replacement" message, and whether the projector might be giving that warning because of some underlying condition about the state of the lamp that it was sensing. But you have confirmed that, no, it is strictly a warning based on the Hours on the Lamp.
Thanks a lot!
p.s. While doing some of my searching I came across a number of very helpful guides that you have posted in the last couple of years. I have bookmarked them. Thanks also for those!
Greetings again Dreamliner,
FYI, it is now late May, 2020 and we last communicated about the RS600 lamp back in September of 2019. I finally decided to quit my risky behavior and replace my out-of-ours lamp. I'd only gotten it up to about 3900 hours, but since I have one of Dominic's replacement bulbs, I figured it was time to dispense with the risk.
Anyway, using the pictures that you, and Dom, had provided at various times, I managed to do a successful replacement. I reset the hours and all is well. And, yes, I see now that even after 3900 hours the lamp had not dimmed significantly. I didn't take actual measurements, which I really should have, but just eyeballing it I can see that, while it is
brighter, it is not remarkably so.
Bottom line: All is well, and hopefully I will get another five, quality, years from this projector.
I think I will, almost certainly, order a new replacement bulb, so that I have a spare on hand at all times. I looked at Dom's thread where he has those bulbs, and I think that they are currently available. So, that's my next stop.
Hope all is well with you and that you have weathered the covid-19 storm, as it were.
