wow
Throw seems better than DX80. Groupbuy? 
only 3, 4 min on highest with active cooling ?
If I understand well from the list it is 3min at 53000Lm.
no one can change physics
stable mode is 15000 cooled
yes i know, was just expecting a bit more.
I think Imalent went with a cooling design that was very easy for them to build and it does not give high efficiency.
Acebeam designed their 40k lumen light using 3 fans for max cooling. Imalent has even higher output and is only using one fan (size unknown). It’s quite possible Imalent sped through the design phase just to get their light out onto the market as early as possible.
This is my theory.
Nice Bundt Cake Pan Reflector…. :+1:
so its using 1 fan only, that explains why it cant run the highest that long. doesntlook like u can replace it urself either?
It wouldn’t be an imalent light if you could replace stuff yourself!
What a strange choice in fan. That type of fan is designed to spin clockwise and pull air towards it’s center. I don’t see how it’s going to blow any hot air out. In order to be effective, the air has to flow into and then out of the light.
Does anyone here see how that fan is going to produce flow through the light?
Maybe it works similar to the FB1 since it uses a similar fan shape.
If this were the case, the MS12 heatsink would have to be divided in the middle of the vent, like this. Cold air goes in the top part and hot air exits the bottom.
It’s possible they got clever and added ducts inside so that the inlets and outlets are a little further apart.
The issue I see with both designs is it sucking in and recirculating hot air from the exhaust vent. You need to space them as far apart as possible.
Anyway, maybe we will get a better look at the cooling system later.
These types of exhaust fans are pretty popular with laptops. Draws heat in and exhaust out the side.

I think your overlooking the obvious.
This style of fan is like a turbo. The air going in is at a 90° angle to the air going out.
This fan pulls air in along its outer diameter, but where does it go then?
The exhaust side where the sticker is…the intake is the fan side, like the blower on a house furnace, draws in from the side, cold air intake, and blows out the exhaust side across the heat plenum into the ducts.
It does look kinda cheap just stick a small fan inside that host and thinking it will do magic? yea i guess it wont, not with that amount of watts of power the leds together will generate on turbo… Not like small fans like that are meant to withstand hundreds of watts of power but it will be interesting see some review tests see how it will perform.
Like compared graphics cards that can get very hot too when playing games, usually its a fan that blows the hot air at the end of card from the heatsink, works usually good.
There is no sticker.
Are you talking about your computer fan picture? I’m pretty sure you got it backwards. The hole in the middle is the intake. You can see the dust build up. It slings the air with centrifugal force out the side. This is how most all laptops work. Intake on the bottom, exhaust out the side.
Going back to the MS12. Regardless of the fan rotation, clockwise or counter clockwise, there is only an intake and no exhaust or only an exhaust and no intake. Do you see my point?
If air is going in, air is also going out. Pretty simple there.
I love the idea, not so much of the 12 XHP-70’s but the fan cooling. They should use that on the 9x XHP-35 and I’d be on the edge of my chair with my hand in the penny jar.
Still, the idea of a massive head with 9 35’s just appeals to me, the stop sign in the middle maybe encourages me to GO!

Interesting, AliExpress is not the cheapest place to buy one huh? lol On the other hand, Lightmalls shows $380 at a discounted price from the $409 suggested retail.
Gonna have to sign up for the group buy just to see how many penny jars gotta go. 
No, that’s not how air flow works. If a fan tries to push air in and there is no path for it to exit, air pressure builds up and air stops going in. It’s all about creating a pressure differential.
Think of a laptop. It’s fan pulls cool air in from the bottom and exhausts hot air out the side. Now cover the side exhaust. The air stops flowing and the temperatures start increasing.
In the MS12, I think the air must be flowing like one of the two pictures I drew. I don’t think it’s design is anywhere near as good as the cooling setup we see on the Acebeam X70 which had clear intakes and exhausts.
