If you could get them to the same level of output, it would make calculating this a lot easier as the relationship between lumens and kcd is unknown.
XM-L has wires across the die, while the XM-L2 does not. Don’t know if this matter.
I send them offer, for I4 v2 + BTU Shocker for 120, lets say if they agree 
Hi,
Got email that mine is coming via Fedex - ordered on 6/8, and in Memphis, TN today, and scheduled for 6/19 arrival :)!
Should be an interesting week :)!
Your gonna love it.
Just wait until dark. And then go play. :bigsmile:
We have two of my nieces, with their families (7 in all) over this week. Should be an interesting Wednesday night :)!!
I was showing mine off all week. My son and daughters friends were amazed. It’s like turning on a streetlight in your backyard. Any light that smokes my TN31’s to me is pretty damn mean. This BTU is mean.
Good idea!,training in preparation for ownership…now that is a sign of commitment

Back again!
Now with XM-L2 and SINKPADS for $15 more!
Awesome,well worth the extra
Is BTU shocker compared, anywhere in this forum, with SP03?
Ordered direct from Ric?
Yes. Same link as in the OP.
You click the selection boxes on the right.
Thanks 
Trust me, the Shocker destroyes the SP03 in every possible aspect.
This was enough clear for me.
Gonna order one.
1B & DRY, right?
That is the brightest possible option available, yes.
Are you saying that the Dry driver is the one to get? I ordered mine without and CW from previous buy. So I got the wrong one??
The other driver has a 3.8A maximum in turbo (with a 3 minute timer before it steps down) and no PWM on any level.
The DRY Driver in turbo is direct drive, meaning if you have decent batteries you can get over 3.8A easy. There is PWM on levels except turbo but it is very high.
Personally I chose the non dry driver since 3000 lumens is plenty for me. Even up to 4.5A the differences are negligible due to 3 emitters being in one host.
That’s cool I was starting to worry that I screwed up. Thanks for explaining it for me.
