Did a little checking and the XP-G was announced by CREE in April 2009. The XM-L was announced in April 2010. Sounds to me like we are overdue for a new LED from CREE!
I get your humor now (I was wondering how in the eff you knew when Google showed nothing). Good thing you are on BLF because that would have gotten you banned from CPF. LOL
ROTFL....yeah...the joke would have gotten you banned.
Anyway, i think the main obstacle is the heat aspect. You really gotta get rid of it for LEDs to shine, which is not good. I think XM-L is really good already, what we need is a higher current capable one for more lumens, like SST-90, but at higher efficiencies.
Actually XM-L has life at 4A, but you need to maintain the diode junction at below 25 deg C. SST-90 9mm^2, XM-L 4mm^2. XM-L itself now has the capability to do 2000 lumens at decently high efficiency.
We all know CREE is aware of the heat issue. Which is why I'm excited to see what they come up with next. I am absolutely amazed at how far LEDs have come in the last 5 years. I have read so many posts saying "This is as good as it gets, they can't get any better" and then a few months later a better LED comes out (not just from CREE but from all of them).
Eventually we may get to a point where they can't make a better LED, but I don't think we are there yet.
Interesting. 12x eneloops in a mag is 14.4v nice heatsink, overdrive it and you should have a beast. Or make a car spotlight that plugs into the lighter… I smell a mod coming.
