If you read this thread you’ll see that both Digikey and Mouser are already stocking the XML2…
This sounds great. So can you tell me, does this mean the XML-2 has a higher output and also will use more power- in other words have a little less run time but just more output, or has the efficiency stayed the same or better??
Feel like holding off on new lights until these start showing up!
Same power, more output

XM-L2 chart is just below to compare
From my experience with the XP-G2s, it seems like the domes come off much easier on the new SiC die emitters. Anyone share the same experience as I have?
I’ve accidentally de-domed three XP-G2s while reflowing the emitter and two emitters survived.
I wonder if this is the case with the XM-L2s as well…
Just ordered Qty 3 of the T6's from Mouser:
| Select |

|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|

3 | $6.82 | $20.46 |

The details are sketchy on this. Does Mouser have the stock or the vendor, Cree, have the stock? If it's Cree, looks like 5 weeks estimated shipping. Tried calling Mouser but they are closed weekends of course. Hopefully can find out more Monday.
These T6's are definitiely 5000K and 75 CRI, hoping they are"3C" equivalent or cooler - not sure how to tell or convert. I chose USPS Priority for $6.99, so total for Qty 3 is $27.45.
Update: reviewed the chromaticity chart (here) again, so for 5000K it should be 3A, 3B, 3C, or 3D. I'm thinking 3C because the only XM-L T6 Mouser carries is the same 5000K and 75 CRI.
Anyone else try ordering these?
I ordered 7 yesterday , they shipped it UPS 2 day
You’re misunderstanding a bit how LEDs work.
A LED uses exactly as much power as driver feeds it with. No matter whether you grab 10A / 40W SST-90, 3A / 10W XM-L, or 3W / 1A XP-E, if you drive them with same constant-current driver, they all will use same amount of power.
To further clarify, the XM-L2 LED's should produce more output when driven by the same amount of power as an XM-L. This is their advantage - next generation, more lumens/per amp at the same voltage and same temperature, same package size. So, if the cost is the same and the bin, tint, and beam pattern&color is all the same, and they actually do perform better as stated, they would replace XM-L. There are a lot of "if's" there though 
and CREE doesn't have a stellar record with filling out the product family offerings, or filling them out quickly.
But if direct drive, say an XM-L will pull 3A, but an XP-G will only pull 1A. If my understanding is correct. Which would be valid to the original question. Basically asking if XM-L2 would handle more amperage or be more efficient with the same amperage.
Don’t beat me up to bad, I’m still a newb 
Direct drive is very silly way of driving a LED. Don’t do it.
I was just trying to simplify the equation by removing the driver.
Could you clarify why it is a bad idea?
Because, with LEDs, current varies massively even with small voltage difference. And it goes against manufacturer’s (of LED) recommendations.
Is that necessarily bad?
Yes, it’s not as efficient as driving an LED at 1A or 2A but we do get the peak brightness of an XM-L at 3-4A.
Plus, LED’s just don’t go poof at even 300%+ of their recommend current, specified by the manufacturer.
The HD2010, one of the most highly regarded budget lights, is in fact directly driven at High mode.
What’s wrong with driving at whatever current you want using a constant-current driver? Direct drive has no advantages over constant-current drivers at all.
Nothing at all, except linear driver using AMC 7135’s burn the excess power as heat.
Other than that, using a constant current drivers does enable you to control the brightness.
Linear drivers aren’t great either. Especially AMC7135 based ones - you can only regulate current in 350mA steps using them, so no option for moonlight and low modes without resorting to PWM.
Yup, I hope we can produce BLF style drivers, preferably a high-efficiency buck driver with BLF’s programmable codes. :party:
Synchronized buck/boost drivers would be best, for those who want to run 1 cell. Buck/*boost* because draining modern 2900/3100/3400mAh cells requires boosting due to them having not-so-high voltage.
Modern cells can’t stay over 3.3-3.4 volts under load?
Anyways, I wonder if we can arrange something with Fasttech about our drivers. /wistful thinking
Nope (at over 2A)
