It looks like the widened optics would still be needed for the XP-L high intensity ones. The highest bin listed is a V2 - a straight droppage of 3 bins which could match the results we've seen de-doming.
Well, I'll get 'em as fast as I can, but there's no ETA at the moment. I was the first to get the U4s, but I doubt that I will be the first here as well.
I came across mention that LED color changes are known over time from operating where there are volatile chemicals (including from plastics or thermal compounds) that can get into the phosphors.
I’d guess the flat clear layer is to seal the phosphor (and perhaps that’s one reason people see color change after dedoming, though I’d be guessing on that). https://www.google.com/search?q=led+volatile+chemical+color+change
That would be a good question to pose to RMM as I’ve read where he mentions using LED seal when he dedomes leds. RMM, can you tell a difference in the tint of leds that you dedome after using led seal?
Read the references — there are observations of tint change due to volatile chemicals that can get into phosphors — but the devil is in the details:
how much time does it take (and is that operating time while heated, or exposure time after some amount of heating starts something gassing out? which chemical, and which phosphor (many emitters use more than one phosphor). Oh, and what solder was used? what flux? what else is inside the container (flashlight head, for us)?
You are right about max flux bin V2, i messed up when i checked the pdf before, i saw a CW V5 high density and thought i was looking at the High Intensity ones.
But isn’t it strange that the High Density ones according to cree only goes to V5? Is the High Density ones different than the old XP-L, I though High Density meant with the dome like the old ones :~
I hope not the XB-H looks at least according to Cree’s data cheats to have lower output than the XP-G2, and that is not even counting the newly released S4 flux bin.
