I imagine they use a battery solution like jetbeam T6. More easy compared with battery holder but a 4s configuration would be better for 12v leds (xhp35).
Anyway nice approach 
Yes liking it a lot, 8mm thick emitter shelf, bypassed copper alloy springs, 40mm DTP emitter board, whats not to like!! :+1: 18awg leads for the XHP70 would be better, IMHO but at 6 amps 20awg will do, unless you plan on pumping it up a bit more?
yes the specs are amazing ,if you need reviewers we are here
With xhp35 hi will have better throw i think.
I sent a pm with a question also Haikelite .
Use a premium thermal paste/grease, make the mcpcb pocket tight to hold centering the LED and screw down the emitter board for better thermal transfer, and also not to allow the board to twist and possibly cut the LED leads, would be a couple other suggestions…if your not doing this already?
Like to see pictures of the base of the reflector too…
Nice, will keep an eye on this.
“8mm thick internal emitter-sitting disk”
Why not integrate head design?
Having an option for XHP35 and XHP70 would be nice. It looks really good…
Watching with great interest. 
For an XHP70 thrower, would prefer an option to be supplied with both smooth & OP reflectors.
The head is integrated. I mean the emitter shelf is 8mm thick for better heat sinking.
Sorry for bad english
Exaggerated lumen numbers those seem, Yoda says. According to the Cree documentation, a 2S2P N4 bin XHP70 emitter would be beaming ≈2300lm at 85°C.
5000-5500 lumens at 6'5A? 
That is with the emitter riding on the Hulksink, in an integrating sphere collecting ALL of the output… 
Sorry! 
Cheers ^:)
P.S.: only low-CRI Crappy White and N00b White? Sheesh! :D
Will get one if reviews are positive and worth the price!
I wonder what it’s like to hold this light. It looks like it’s head heavy, so you have to grip it in front of the buttons where the cooling fins start to keep it balanced. Is it comfortable to hold in such manner for a long period of time…
Thanks for point that. In fact The body is much heavier than the head with the 4x18650 batteries installed. The balance is comfortable to hold.
Like the looks of this light as well. Will the led be mounted to on copper DTP star? I think a smooth reflector xhp35 hi would make a great thrower.
I like the heavy block vertical (Fins) heat sink(s) at and below the emitter shelf, having a integral shelf, this should do well to dissipate a substantial amount of heat! Hopefully the inner cavity walls are thick too!
From the OP i suppose so :
Man this thing looks thick and juicy…. me like very much so far…
The UI looks similar to the Olights with two switch improvements, which is great. Can’t wait to see what this thing can do.
