Anyone have any idea when the Cree XP-G will be available? I'd really like a Quark, or another D10; but if the XP-G is around the corner, it may be best to wait.

~135lm@350mA and 347lm@1A in XP-E package. More floody beam but huge amount of light.
I find MC-E's kind of useless oh high because they get too hot too fast

So they won't be used for 'throwers'??
They could just redesign the reflector, make it deeper, whatever. Things will work out. =)So they won't be used for 'throwers'??
Thermal properties should be as good or better than an XP-E given that the increased light output comes from higher efficiency at the same power. They claim drive levels up to 1A (like an XR-E) in the XP-E form factor, though we'll see if they stick to that or spec them for 700mA like the XP-Es.
Efficiency is up to 132lm/watt, and even their high-CRI 92% @ 3500K warm emitters can manage 102lm/watt, which puts them in the Q4 range.
edit: This thread should probably be under Beyond Flashlights -> LED
XP-E vs XP-G:
Slightly larger die size (note the four sections), but it's not like it's a P7 footprint.
That depends on what you are using your light for. if you just want to find something in the garage, or need a wall of light for a short period, mc-e works great i think. i would not bring my mc-e or p7 for long trips in the mountains that's for sure.
Whoops, my bad on the @350mA vs 1W mixup. Their high-CRI warm tint was demonstrated at 102lm/W, which would mean they were R2 bin then.I believe it would be the Q5. The Q4 was above 100lm/350mA but as far as efficacy it was the Q5 that was around 100lm/watt. The R2 is the one that broke 100lm/W. CRI is also stated as a number and not a %. Don't mind me nitpicking.
