Which it does. A 90k hour tube and a 5k one measuring exactly the same. Does this not suggest to you that the phosphors have not drifted wildly in the intervening 85k hours?

At this point I may as well ask your profession credentials? I was test technician for pic related before it was absorbed into amazon and relocated to the US. I then moved into test and QA inspection for a tier one fiber optic subassembly manufacturer working on 100+gbit transcievers and most recently have entered the aerospace sector as QA for the biggest name in aero engines.
