You could always wait for the Astrolux EA02 
@PiercingTheDarkness
It’s to big for me I think. Don’t want bigger than M21A which isn’t pocketable.
A vote here for the M2+NM1. Runs cool enough at 4.3A and settles into a pretty sustainable 80 kcd while still being cool enough to hold. Really a slim light that handles heat very well. Comes with a (strong) pocket clip if you care about that.
M21B is a better host for bigger emitters IMO. Interested in seeing actual measured values and opinions from someone with both.
34-45mm bezel is an awkward size for me. Too big to pocket EDC, and so if its going in a bag or holster, you may as well jump to a 50mm class the way I see it. After 55-60mm, I feel a light should be multi-cell, so that really creates another big step. The EA02 looks like a nice size and configuration. Super deep reflector. I really hate that its a blatant rip-off of an FF design though.
For maximum lumens, I would go with XHP50.2, but it looks like it is no longer available.

Since that seems to be gone, I'd go with the SST40 version.
50.2 isn’t a thrower. With the thermal limitations of a host this size sustained lux will be worse than a s21b+pm1
You just said above that you might get something less pocketable
@PiercingTheDarkness
Yes but I mean something ~M21A sizes 
Anyway, thanks for suggestion. Maybe on photos it’s bigger than I think.
Oops.
I changed my mind about the BLF-D80v2.
At $27.70, it's a good deal, but right now it's at $37.70, which I think is too much.
Sorry about that.
I read a topic about this flashlight and for BLF member it should be 27.70$ (or it was months ago). I will try to buy it with discount maybe, which one will give me better throw?
Spend a few $ more and get a noctigon KR1
Actually $28 ($33-15%)

I like this idea I am going to do it to my M21B where do you get your dual springs from?
Zam get the M21b great size that’s if you have 21700 already.
I just use a single one of these over the top just don’t do this on the head in case it delivers too much current. Using the 30Q I measured 8.4A at turn on, the LED peaks at around 9.4 ish so 8.5A is fine. I’ve sold plenty and haven’t had a single issue. Not sure what you’d use for the 21700 though
Thanks for that just went to order the parts but cannot find the ramping driver?
I will add that the only reason I have dual springs is because it’s a gun light, stops the battery disconnecting with the recoil. A single one of those springs would be enough.
Installed a BeCu spring I got from BlueSwordM in the Sofirn C8F and that Convoy spring performed the same in it, so you should only need the single spring
Sweet never looked at that one because it had SST40 on it.
Now just need to go order all the parts thanks for all your help. Nothing better than a light that can work so hard you can blow the LED up in it love it.
thx
