There are ways to do miniaturized water cooling involving small fans and aluminum tubing. Think, high performance cpu cooling.
It would be impossible to retrofit though. The tubing would have to be manufactured structurally into the mounting plate of the LEDs and possibly into the body to save space.
I don’t know what sort of space is used for cooling in the design of the DX80, but I’m guessing it could be accomplished in about an inch of head/body tube space. Would involve a small fan and tiny radiator, and some venting. Natural heat driven fluid circulation.
Would probably drive the price up another $100, though.
Oh well, Gearbest just listed this light as well. With discount code “DX80” they’re selling it for $220 or 190 Euro. Pfff, what a great price… And that’s with 8 pieces of their protected Samsung 30Q batteries…
I do hope that they will add a spare driver in that box The heat caused will fry the default one in no time, my DT70 died after only like 10 hours of moderate usage( driver fried)
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.
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 )
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.
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
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
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.
The heat caused will fry the default one in no time, my DT70 died after only like 10 hours of moderate usage( driver fried)
