CPF has a thread on it and Eagletac has a light out already with the XHP50 in it. Limited edition, which means they got samples from Cree before anyone else.
5x5 footprint and 7x7 footprint. Even with 4 dies, a 5x5 footprint should make a light that could be? a fair thrower and replace XM-L2. 7x7 would replace MT-G2.
I would guesssssss..... that the dome will help eliminate the normal black cross shadow, that you would see in a 4 die setup and the dies look like they might be tighter to each other, but that might just be the photos. I would think in a bigger deep reflector, that has the bottom third/half in an OP finish and the rest SMO, it might just throw pretty good in the 5x5 format.
I asked Cree to let me have some samples, but I won't hold my breath. I don't expect an answer since I don't have any pull like the flashlight makers do.
" At its maximum current, the XHP70 LED delivers twice the light output of the industry’s brightest single-die LED, the XLamp MK-R LED, at a similar lumens per watt and without increasing the package footprint"
Lie nr1:mk-r isn't single die led
Lie nr2:even if mk-r were single-die,luminus cbt-140 is still brighter
Typical CREE marketing.
Anyway,it looks like xhp50 is 4x XP-G2 and xhp70 is 4x XM-L2 die.
