None of these 20k lumen and up lights are really throwers. You need to have a certain emitter die size to reflector size ratio for good throw.
Now if each 70.2 had a 2.5”–3” reflector, then you’d get some pretty good throw, but the head size would be huge! 
I was going through the throwers on parametrek when I realized the X65 had more throw than the X70 and I thought, “Wait wait wait. What?” And that’s when I finally looked at the head of the X70 and realized just how monstrous an X70 would have to be if each LED had a reflector like the X65 does. It would have to be vehicle roof mounted!
Imagine an X65 with the head size of a 4Sevens XM18.
It would have 12 slightly bigger reflectors, instead of the 18 smaller ones you see in the pic.
Where do I write the check out to? (Just kidding my wife would kill me.)
Edit: would be a great recommendation for all the people asking for a “self defense flashlight.” “Buy this thing, it’s a medieval mace with +3 fire damage.”
Isnt lights like this meant to just shoot tons of light like crazy vs throw very long? not really like throwers even tho this one is gonna go for like 1km it still impressive but u wont get that tight beam tho. Also u can take a swing at someone in case self defense would be needed lol… Im curious how the final version will be like and if they ditched the fans it means they had same issues olight had…
Possible radiator and coolant?
Wrong way, they want to make it simpler, not more complicated. BTW, it would still need fans for the radiator.
What other ways are there to actively cool besides using fans?
I hope they dont do passive cooling 
That’s the only practical way to do it.
If neither acebeam or olight can manage to produce lights with active cooling then it seems something is wrong no? because waterproof fans etc exist so i dont get it ?
I doubt they can go fanless, even the x9r if i run for almost 3m it gets quite hot at the head, so that much more lumens is almost worthless if they go full passive since that light will produce more then what 220W of power ?
Oh they can produce it, but they may not want to go into production with it. There’s lots of possible reasons for this.
C02 cannisters?
Maybe they can bundle one of those misting fans with each light. Put some ice in the bottle and every time it gets too hot you just spray it a couple times.
Edit: That was a joke, in case anyone thinks that was serious.
But i dont get it, acebeam showed earlier the prototype with 3 fans, same did olight so its weird if also they now ditched the fan design, the light will cost alot more then x9r so for that much lumens i think active cooling is a must if they want longer runtimes on max then a few min …
I do believe that those three little fans are about as good as useless against this kind of heat.
My thoughts. I think they overestimated the amount of heat the fans can dissipate.
makes sense when u think about it, such fans even if 3 in that head can they really push out that much heat fast enough? probably not… but who knows.
Not at all. Based on my calculations, it just might be able to do 40k lumens continuously. It’s kind of at the limit.
Now 30k continous is definitely doable.
So if 40k lumen is borderline, I could definitely see it doing 40k for at least 5 to 10 minutes, then step down to 30k for the rest of the batteries life.
Even this is a huge step up from the 7k continous lights we currently have.
But once the batteries drop half their capacity, the volt isnt too low too keep up that much lumens? im skeptical… my olight x9r i cant do 2 highest modes once battery shows 4 bars out of 8 left… ?
I’m sure the output has to step/ramp down once the batteries start to drop voltage. This is normal.
