OK , all my SSC P7 [ single 18650 ] are around 500L
The little A20 on a RCR123A blows them all away ...
EVEN the SST-50 [ mine did 500 ] is rubbish compared to the XML ........ Howzat !!!
I cant wait to get my hands on the T6 's and build some P60 drop ins [ RIP = SSc P7 / MC-E / SST-50 ]

though, for all out there that are far more expert than i am at this, will it be viable in a small, say 14500 or single 16340 host?

Did you get a chance to measure a tailcap current yet?

Updating original post as I go ....
Yes , Im sure you can use the XM-L with a 14500 or 16340 light [ I did ] .
Just cherry pick the driver you want to use , since I dont care about shortening the life of a RCR123A [ I have plenty of them ] , and I also usually dont run high , except to show off , and as can be seen , on low , its 100L . Damn , a 4 mode driver or ramping driver would be real nice [ for less than 100 Lumen output ]
Butt , 0.25A and 100L = I used to think 0.25A was OK for low , not anymore .

@old4570
Is this possible?
High / 1.77A / 620L
Med / .69 / 250L
Low / .25 / 100L
620 lumens with only 1,7Amps?
250 lumens with only 0,69Amps
100 lumens with only 0,25Amps?

Seems a bit overrated since there were reports of 600-700 lumens at 2,7A

Cree's documentation on the XM-L is 260 lumens at .7 amps for the T5 bin. 658 min flux at 1.77A to the emitter by those numbers.

ummmmm If this is possible I will transplant many of my lights to xml

If it does true 600LM at 1,8 its a real winner!

The current measurement is as measured : I cant measure current and light output at the same time [ Id need 3 hands ]
So it may not be entirely right , current may be slightly higher in use [ less MM ]
Unfortunately the A20 unscrews in the middle ... This is only as a guide , sorry , I dont expect it to be 100% , but just to give you an idea ...
Its getting dark now , Ive charged up some 18650's for my SSC P7's , so lets check out the beams ...
But yeah , a bad light for matching current to output , I should have some XM-L T6's in a day or two , so I will build some drop ins for my L2 Hosts
Then I can measure current and output at the same time ...
Beams shortly

Try this , beams as gif ....
Its cloudy , so way to much city lights [ reflected from clouds ] , so very bad conditions for beams , but hopefully you get an idea ...

That's a neat way of doing beam shots, but can you slow down the frame rate a bit? I don't have quite enough time to look at the picture *and* read the caption. Maybe 2 seconds per frame?

Nice GIF, I'm glad I got the larger reflector of the C8, even though several of those XM-L lights have literally the exact same beam shot images on KD. :/ The A20 is not quite big enough even for a flooder, but DANG can it flood. :D Awesome.

Cutter has 14mm boards ...
Posted a link [ first post ] for full sized pictures if anyone wants them ... Will try for a slower gif
