Being so light, how does it dissipate all the heat ?
It has a DTP 31mm copper board in it and it also has a large head with some good cooling fins on it
We did tough heat testing. Left it sitting unmoving and on full power in the house several times for 70-100+ minutes continuous runtime and it got quite hot, but when moving outside you can feel some warmth in the tube but no more. Airflow thru the fins works well.
Out hunting for hours on Friday night and zero heat issue - just slight warmth as you walk/drive. Good for cold winters 
Well all righty! I am in! Sounds absolutely wonderful! Turgid with excitement ,anticipation, and curiosity! :cowboy_hat_face:
Oooh nice. 
I’ve noticed that with my C8’s out possum shooting. Airflow is certainly the key.
Fins certainly work - and well.
Can’t wait…… 
Hi David,
I can hardly wait to get this beast into my hands.
I’m also curious ——— will it beat the Acebeam K70?
Subscribed! And thanks for the great beamshots robo!
By the way I have a few questions about this light…
Is the reflector exactly the same as the previous version (in terms of diameter and depth)?
Who did the XM-L2 U4 1A dedome?
Is the CRI of the dedomed XM-L2 U4 1A really better than the XP-L HI?
I haven’t kept myself updated with flashlight stuff for quite some time so there might be some new findings nowadays…
Looking forward to seeing the price on this one, I want a real long-thrower!
I can confirm that yes,yes it is. The HI almost washes out
colours.
It’s much cooler than the U4, and from what I’ve seen ( and I like cool tints, so this is hard to type lol )
The U4 is the way to go.
Could there be a integrated picatinny rail mount battery tube made available? Any chance for thermal encapsulation (heat/vibration /recoil) dampening of components for reliability, from sustained fire of large caliber weaponry? Is the head to battery tube adapter or mount still of the 4 screw attachment design or integral?
We did alot of field testing and David (Robo) did heaps of side by side photography assessing CRI and object picture clarity at 200m plus. CRI defined as: the ability of a light source to reveal the colors of various objects faithfully in comparison with an ideal or natural light source.
Three main candidate leds - the XPL-HI, XML2 U4 1A, and XML2 U4 1C. We rejected the domeless XPL-HI quickly - cooler white tint in our led supply which as Here and Again notes blued and washed out colors down range. After alot of testing we chose XML2 U4 1A - much more natural picture down range and far better clarity. XPL-HI also less efficient - in comprehensive testing its lux output is approx that of an XML2 U2, but U3 and U4 alot better. Tested various leds in same torch for exact reference.
We had new 2X running at 370k with XPL HI but to get this it had to run at 6 amps - not stable and requiring step down after 2-3 minutes. Stepdown no good for hunting. With more efficient XM-L2 U4 we could use 4.5 amp boards with no stepdown for about same 360-370k output - plus better picture.
Acebeam too big for our purposes at around 800gms or 1.8lbs with batts, 50mm tube and big 88mm head. Slightly higher output than new 2X, but not weapon mountable, twice the weight, uses twice as many batteries, and more than twice the price. New lightweight 2X could be round $90…we’ll see.
And that is the key.
No way I’d pay Acebeam money for a torch.
That’s just what the world needs now (and how….)
More good news!! 
Thanks for the input guys.
So the dedome is going to be done by Maxtoch themselves?
Yep
Is the reflector geometry same as the previous version?
Unsure. It is a new and different head design.
As good as the BLF M24 was, this is going to be another must-have light even for those of us who don’t regularly hunt. The price makes me cringe but you don’t get what you don’t pay for and this will be an awesome value- count me in

I did the dedome on this particular emitter as well as the ones I put in my M24’s. Have not received the factory built light yet , but I did receive the driver (furnished by Maxtoch) and used the same emitter and MCPCB that will be in the lights from the factory. As stated in the OP I will do a full review and teardown (also post beamshots from the factory light) as soon as I get it.
As Mudgripz stated, after a lot of testing and side by side comparing , the Dedomed U4 is much better than the HI emitter for clarity and CRI downrange. This holds true in the M24 or the 2X lights , as I have both and have tested both LED’s for comparison in the 2 lights.
Here is a comparison of the two emitters. The XP-L HI and XM-L2 U4 1A dedomed with 4.5 amps.
Although taken about 3 weeks apart, the pictures give a fairly accurate account of the difference you see between the 2 side by side , as the XP-L HI always looks more hazy and has more glare to my eyes , and does not show the colors as well at distance.
