I do not have any problems with my collection of small, medium and large size/weight lights that are so excitedly capable of releasing all of the power of the cells in a brief blaze of glory. Why? Because I keep the blaze of glory brief. When I feel that the light is beginning to get hot, I throttle down to lower mode.

There is no ultra high performance light that does not “suffer from this… illness.”

Most all ultra high performance lights will get hot quickly. The problem is caused by the user not selecting a lower mode when that happens.

I do not blame the manufacturers when their ultra high performance products have to obey the laws of thermodynamics.

Realy? They claim 32k, 50k or 100k or so lumens, they HAVE to maintan them OR maintain the torch stability otherwise

And they did, at least they tried….yet, when you put that power in that kind of a body usualy “sweets” happenes.

3 XHP70 in that bpdy okey…4…..maybe okay but double that number? Excuse me

I wont even talk about batteries temperature, thats another quite risky issue too

If a light fries itself due to the heat it produces in stock form, it should not have been released IMHO

If this 32k light indeed does have a fan that could very well protect the driver and cells from heat, that would be awesome
But again lack of info makes it all unsure.
I feel more and more inclined to think that lack of decent info on runtimes and such dus more a sign of sure shortcomings but we will see when the first real life user experiencces reach us (and that afhinese “review” was about outside and missed a lot (or well maybe I missed it, then I hope to stand corrected Wink )

Are we reaching the practical limit of hand-held flashlight output? As everyone is pointing out, the heat that such a beast will produce could start to seriously damage electronics and batteries. Without some form of really good active cooling, you might only be able to run a light like this for a few seconds on max.

We’re probably talking about 200-300 watts of power needed to drive a 32,000 lumen light? Well over half of that dumped as heat into the light. Try holding a 100 watt incandescent light bulb for more than a few seconds!

I dunno… it sounds impressive, but if it only runs for a few seconds on max, is it really 32,000 lumens? Is my camera flash really 1,000,000 lumens? IMO, it’s got to run safely for at least 3 minutes before stepping down, to qualify for 32,000 lumens.

If your camera is able to produce 1,000,000 lumens for 30 seconds, then yes according to ANSI. Big Smile

Eight XHP70 in a flashlight? Great! I want one.

I already know that ultra high performance lights will get hot in a few seconds on max. I already know that if I do not throttle back to a lower mode in a few seconds, the flashlight will melt down. I do not expect that the flashlight can run safely for longer than briefly after it gets hot. I already know that the advertised max lumen spec is only for a few seconds, until it gets hot, and then I need to throttle down to a lower mode to prevent the product from frying.

Ultra high performance lights are not marketed to target purchases to be made by neophytes.

We, who are enthusiasts, already know that ultra high performance lights need to be quickly throttled down by the user to a lower mode to prevent the product from melting down.

We, who are enthusiasts, already know that the advertised max lumens are for short burst only, due to limited fuel supply capacity and heat management.

Yet, when any manufacturer offers an ultra high performance light that is marketed to target purchases to be made by enthusiasts, we complain that the light gets hot too quickly, and that the flashlight melts down when it gets too hot.

I feel grateful that manufactures continue to offer new developments in ultra high performance lights, even though when any manufacturer releases such an new, exciting product, there will be enthusiasts who point out that the light gets too hot too quickly.

Well would you want to watch a 30feet drag race?
Lights like these, if build as a mod are awesome. But sorry for a professional party just smacking a whole lot of LEDs in there isn’t so impressive IMHO. Add special provisions so it can have higher output for longer then walhat we enthusiasts could build with a big head light and then we start talking Wink
I read about lights that step down to 1200 lumens after just a few seconds.
Would you be impressed by a car able to run at 2000hp for 20 seconds to throttle down to 50?
For me, heck yeah if it was build by some guy in his garage, heck no if a company dare to present it as a 2000hp car.
Of course opinions can Cary widely Wink

I see your point about the 30 foot drag race and the car able to run at 2000hp for 20 seconds to throttle down to 50hp.

Point taken. Smile

All of the manufacturers should advertise Short Burst Only for hot rod flashlights.

That’s exactly what DN70 does ! a monster 3800lm small light that run 30secs…haha after drop to 900lm…Well a good S2+ will do 1000lm.
I hate that way of advertising products. A good product would say 2000lm @2min and then 1000lm until LVP. That’s the way to go.

Flashlight world is doing the moore law ? Since XHP released LED manufacturer are going the wrong way.

Please build a solid 2000lm or 6000lm lights that can sustain 30min of runtime at these specs. Engineering a head with suffisant cooling is way more difficult. I think that my son can produce a light with my lathe and put 8 XHP inside. No problem but when it comes to power on…oups i forget the main part of the light ! Heat management.

Actualy, some of us use those short bursts of power as they should be used, 10-20 secs tops for a quick observation, and thats okay
I personaly do it quite often when hunting : with either my mounted torch, or mu hand one, or with the powerful offhand torch when i am searching for the animal body or a track or smth

The thing that is not okay is the flashlight( the driver, yes) sability on a long term base…and my personal experience says its not okay, especialy talking about those fansy boost drivers

A heavy modded X6 also drops at about 1200lm from 4k in a minute or something, but my personal one is already 1.5 years old, i use it quite often yet its stable as a rock.

Of course it’s going to step down. I’m just worried the light is going to be stoopid bright when switched on… then after 10 seconds or so it steps down to moonlight mode… forever… and it’s not getting brighter anymore… $220 is really nice, but at the same time this price on day one for such a caliber of a light just seems too low, and worries me as well.

(And two days later I get a reply from customer service: “we can offer you a $5,- refund.” Facepalm )

There is no way that this light will step down under 5000 lumens after it reach 50 degrees Celsius. Actually it will all depending on outside temperatures. With body mass of 1kg I expect that it will run for a 60 seconds from 30000 to 25000 lumens and then it will step down to maintain temperature under 50C….

Whell that is just my opinion and, I hope that I will get chance to get one of the first production samples like I did with DT70 and get the true readings of lumens and temperature.

This looks more like a custom product to show off lumens than one designed for real use. I’d rather have 3 or 4 emitters in much larger reflector for double the throw and running at high power through the runtime. What’s the point of having a light that can only run continuously at 15% of its full potential?

Why couldn’t they invest the R&D money into making a proper active cooking system instead of cramming as many emitters as possible in a flashlight? For me this is more like a fetish product for pleasing people with fake numbers, maybe winning the lumens race is more important than making a practical product, I don’t know.

“Active cooking system”. Lol. I’m not sure if that’s a typo, but it’s probably accurate!

I don’t have a problem with an active cooling system in a high-powered light. But it has to be small and light enough that the light is still easily held with 1 hand. And preferably will fit into a jacket pocket, though I get that throwers probably won’t.

The largest (and brightest) light I have is an old hand-held spotlight (150 watts, iirc, maybe 200?). Powered by a SLA battery, it is large and heavy and only runs for about 5-10 minutes. It is well-balanced, so easily held in 1 hand, but very impractical. A fun toy, but that’s about it. Heat isn’t an issue, because it is incandescent and the bulb is out in front of a large reflector.

LEDs and electronics make such a light way more difficult to design, in order to get rid of all that heat where it’s not wanted.

Maybe the solution to making super-bright lights is to go back to incandescent bulbs? They’re inefficient, but heat is easily dealt with by placing it far away from the battery. Plus, there’s minimal electronics needed. Okay, there’s the issue of run-time, which will suck.

There are so many kinds of flashlights. Lots of very different kinds of flashlights. Very small lights. Moderately small lights. Medium size lights. Big lights. Very big lights. Some people like lights of different size and different types. Some other people only like certain types of lights.

I like to post to say what I like about the lights that I like. There are several types of lights that are not interesting to me, so I do not post in those topic threads, to say why I think those lights are useless to me. I just simply let those nice people enjoy posting what they like about those types of lights. No posts from me telling them why that light is useless for me.

Maybe, one day, people who don’t like the lights that I like will return the favor.

they should have a build in a fan

The heatsink with fins inside the body is pretty useless, if you ever saw the passive heatsinks that have to cool only 100W you know what I mean
they are huge, this heatsink in there is just a joke, a massive aluminum block would be better

@richbuff, we know manufactures read BLF, so also critical posts can have influence.
With lack of info makes us speculate awaiting real user experience.
I really hope the people that have already bought this are going to e dry happy with it for sure.
But point taken, will wait till more is known Wink

I’m a little bit more optimistic. Two things I’d like to note. First is that the passive heat sink examples you have shown is probably for steady state operation of the 100W CPU (?), meaning such large passive heat sinks are required for a maximum temperature for normal CPU operation.
The DX80’s passive heat sinks are not meant for steady state operation of 32000 lumens, but (1) to extend the high output for a longer period of time compared to when it doesn’t have this structure, or (2) for a higher steady state temperature of around 5000 lumens.
Secondly, looking at the first picture you’ve posted, there is thermal resistance between the heat source and the heat sinks, in the form of these slender copper connectors. I think this is a fairly weak link for efficient heat sinking. The heat sink of the DX80 is (hopefully) more efficiently attached to the heat source: led board > shelf > heat sink. The surface is also fairly large.
So at this point I’m a bit more optimistic. Party

But how about the following idea? So you have these vent holes on the side of the light. What if you attach a small compressor on one side for forced ventilation (active cooling)? Obviously this is not going to work outside, but is merely for experimental purpose. I mean this thing is going to cool like crazy or what? I’m interested how this is going to influence performance and step down time of the light… Evil

Who knows maybe the total surface of just the heat sink of the DX80 is more than that of an entire Acebeam X80…

Maybe it will be okay if tightly hand-held, so the heat has somewhere to go. Probably not at 32,000 lumens, but perhaps at 5,000. I find that it’s tail-standing that really heats up a light, even at moderate output levels. (Nowhere for the heat to go, after it has warmed up the metal of the light.)

Or… you could use it as a dive-light. LOL

It sounds like Imalent and Acebeam are probably having a bit of an arms race, with the DX80 and X80.

Between the two, the X80 looks like it could make a useful “mule” type light at 1.1 cd / lm, and the DX80 has more of a typical EDC beam at 5.1 cd / lm.

Of course, neither one is small enough for EDC, but they could be useful for other purposes.

I can’t really complain about having a turbo mode which can only run for a short time, with a stable output level only a fraction of the maximum. Pretty much every single-cell triple or quad falls into that category… and they still manage to be fairly practical items.

The (D)X80 seems less practical (more specialized) due to size and price, but its hotrod nature doesn’t automatically disqualify it from being worthwhile.

I centainly affirm this light have NO active cooling system otherwise imalent would inform and repeat in every ad……

So, I need which Imalent proves that light can be useful and can do more than Thorfire S70 in continuos output….

About the cooling system yet, I dont look closer to this DX80 but if this thing dont have holes in the tail or near that, those holes in the head almost do nothing and even in the tail have holes the convection flux will only works effective if it tailstands or the head stay in higher level (non practical use light)

Saying that, for me the lights with active cooling should be sold long ago!

Hmm, my “little” 3800lm DN70 will run about 90 seconds or so on turbo before the heat warning begins to flash. It will cycle down to 1800 and continue for quite a few more minutes at that level. Or, I can run it at 2500lm for several minutes (maybe four or five?) Before it cycles down. In real life, it seems a long time to have it on :). On my hikes, I often run it in 2500 for few minutes to get my bearings, then cycle down to 300, which, due to the excellent beam pattern is plenty for normal hiking.

I guess one gets used to the personality of the light and the way you use it over time adjusts. I never think about it much any more, the manipulation of it to fulfill my needs is just natural, and not hindered or dictated by the step down. Love it!
