Acebeam X70 - 40000 lm - 8*18650 - Active fan cooling

I wonder how this can ever work out. Even submerged in water this should be WAY too much heat generated even for 15 seconds. But I’m sure someone here can do the math.
Just think about the gigantic cpu coolers with triple 140mm fans you have nowadays to keep temperatures below 80°C and they just generate a quarter of the power.

600watts of power? holy cow thats like a mini nuclear power plant in your hands… totally insane of amount of heat generated…. shall be interesting how they solved the cooling inside….

I start to worry this light can be a real dangerous light if they dont put in proximity sensors like olight did and the risk of burning yourself must be also high…

Fortunately most of that power is converted to light instead of heat. My 80+ platinum power supply can run fanless on my overclocked i7 7700k with overclocked GTX 1080 and three harddrives, which produces a couple hundred watts.

You can’t say “most of that power is converted to light instead of heat”. I think only 25% to 30% gets turned into light. The other 70% to 75% is heat.

I think you’re confusing driver efficiency with LED efficiency. A good buck driver might be 92% efficient. So your computer power supply might be pretty efficient, but it’s not the main source of heat.

I stand corrected :+1:

Its official, lights will be available to ship by the end of next month. Preorders are now being taken.

Acebeam page updated. Now its 60k lumens

This light will probably set the bar for a very long time if knowing acebeam and their quality. Now its only wait and see what the actual runtimes will be and how long it can last with 600wats, but damn that much lumens is just insane…

That is the coolest looking light I’ve seen in a long long time. Reminds me of the BTU terminator on steroids.

Solid looking light. If they dropped the price to around $300 I would probably buy it. Too bad acebeam doesn't do group buys.

OK that is pretty awesome right there, these light manufacturers are really pushing the limits big time.

Now I see something a little different, is the flashlight itself actually fan cooled WITHOUT the handle or does the handle add a secondary fan to help with cooling orrrrrrrrr is it just the handle that is the fan cooling?

That is def a new idea you don’t see done much. I wish they would add more mass to the head of these giants to help with heat a little more.

I do wonder tho how much the human eye can tell a difference between 30k and 60k, maybe some of you could have some information on how the human eye handles that levels of brightness

They removed all the internal fans. So now it’s like a conventional flashlight with an add-on fan handle.

Thats interesting! Thank you Jason for the answer

As for “how much brighter”. I think it kinda depends on the reflector design. With flood lights, 30k vs 100k lumen flood lights, there isn’t a MASSIVE difference. Where it gets interesting is the lights with larger, deeper, reflectors with a range of 800-1000+ meters. While a light like the WS10 might be 250 lumens and 1000m, it’s a pencil thin beam. So with massive numbers like this, instead of illuminating a door 1000 meters away, you can brightly illuminate the side of a warehouse from 1000 meters away.

The reflector where XHP70.2 sit in seems to be much shallower than MS12. I think it will be much more floodier than MS12. The middle XHP35 HI will be in charged of the throwing mostly. Wonder can it hit 200kcd.

I imagine the XHP35HI alone would get 200kcd, looks like a decently deep reflector

From picture it seems to be about same size with Utorch UT02, that is why I think it might hit 110kcd for the middle XHP35 HI, and the rest XHP70.2 can make up the 90kcd. Just a wild guess. :sunglasses:

The UT02 is really weak. It’s only putting out 800 to maybe 900 lumen. I’m sure Acebeam can bump that up to twice the lumens.

That is true UT02 is weak as stock. But I think it is quite tough to reach 1800lm for Acebeam. We shall see how it perform in Q4 2018 when it is released. So excited with all these giant flashlights. Too bad not enough fund to purchase them at this price.

why no steel bezel? would look alot better imo, but curious how it will perform tho still not certain if it was a good idea ditch the internal fans? that “thing” looks sure odd haha it will be noisy as hell probably.
