I really didn’t notice this big openings on the both sides of heatsink… Now I am more optimistic about heat management :+1:
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. :laughing:
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!
Its very funny you tell this about race and cars because almost all “huge” “engines preparation” with turbo charger claims unreal horsepowers values but you cannot use that more than 6~10s otherwise the engine blow :person_facepalming:
We cannot admit some products with the motto “you have it, but not use it!” :confounded:
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!

I think you have a special Dn70 because my little monster is a throwteller monster!
Mine run at 3800lm 1m30s then step-down to 800lm!
After that if I run to 2500lm it run 1min and step down to 800lm.
In fact if heat protection has kicked then it step-down very fast.
That s a 800lm light with turbo at 3800lm
Here is the truth…
I just did measurements of the haikelite SC02 on turbo during 8min no step-down… I stopped the measure i was happy to get a turbo of 2000lm during that time. And light was not hot in hand.
That’s a real ad description for a light.
I say good job haikelite and imalent bad job. So I wait some review of the dx80.
Weight doesn’t mean anything that’s just inertia of heat up… Cooling fins is the key.
I got on my mill 8 xml2 on a pure copper bar of 800grs!after 3min temp raise to 80deg Celsius. I got a aluminum cooler with fins designed for 6 top-3l transistor ramp and now running at low temp. In fact my heavy Cooper bar is needless aluminum well designed fins work much better…
hIKARInoob, those little copper thingies on the CPU coolers are heatpipes
Filled with a liquid at low atmospheric pressure and covered by a fine mesh acting like a capillary fluid transport.
The heat source boils the liquid on one side, the heatsink side condenses it. It is a highly efficient and fast way to get heat from one side to the other 
Yes how silly of me to have overlooked that. :person_facepalming: There’re minituarised versions of this in smartphones as well right? Couldn’t believe it at first until I saw the tear-down video…
I’ll check it again, but those were the times when I first got it. It’s seen a LOT of use since then. Hasn’t faltered.
Will post results.
I believe the SC02 does not have constant voltage circuitry, and it continually dims once turned on (someone feel free to correct if I’m wrong). So, during that 8 minutes you are constantly losing lumens from the initial 2000.
False
My lux meter doesn’t change during these 8min or less than the resolution…
Bluzie strikes again
Proud to buy MT01
Although the last couple of posts are not related at all to the Imalent DX80, there is something interesting going on here. Haikelite started horribly with the MT03 and MT07 lights, which simply were a disaster. I never thought they would recover to the state they are in today. There may be issues here and there, but overall the products are of really good quality with good performance, and a very, very competitive price. I mean if Mountain Electronics is selling them they must be good right? Haikelite is only a one year old company, and they’ve probably worked their butts off to be where they are today.
Imalent is considered to be a young company, but they’ve been around for some years now. And the simple truth is that their products are not considered reliable by a fair amount of enthusiasts… On Facebook Imalent wrote today:
“Hey Everyone! Some news on the DX80, Our first batch has already been sold out to distributors, that means that of our available flashlights, they are now available for preorder as of today! They should arrive on August 15th, and the second batch should arrive next month. We know you’ve been waiting super patiently for the brightest light in the world, something this awesome takes time to prepare and we want to make sure you guys get the very best! Make sure to check your favourite distributors online to see if they’ll be holding the DX80, and we’re working hard on ramping up production as quickly as possible!”
Yes I hope so too. I genuinely hope they have produced the very best with the DX80. It’s just a matter of time and we will experience the first reviews. I have my fingers crossed. And if Imalent messes up (again), then perhaps Haikelite should step up and produce a stupid bright monster light for a really, really low price…
MT03 and MT07 is an excellent light in my opinion granted i probably got the latest improved version but for the price it really is awesome and solid lights.
Cant wait for Haikelite’s own version of monster light, come on Haikelite give as 18K lumens monster or a thrower version of MT03 that would be nice.
As for Imalent i only have DN70 which have been a solid light, i also hope that Imalent get it right this time with DX80 they need it.
Hmm…Ok, gotcha on the stepdown. Maybe I’m misreading the Taschenlampen wiki review wrong?
From the Taschenlampen wiki review -
“Unfortunately, recently, some flashlights enthusiasts confuse the turbo mode with a permanent lighting.
This does not work with the SC02 of course.
Here, however, at the 1000 lumen stage, a lot of light is available. If you need some more light you can activate the turbo.
In a runtime test I have the HaikeLite times a little tormented.
I used an unprotected Keeppower IMR26650 with 5200 mAh.
It was charged to 4.22 volts.
I did the test at a room temperature of 24 ° C without cooling.
The SC02 holds the initial brightness about 2.5 minutes then there is a step down.
This (stepped down) brightness is held for 4.5 minutes before the temperature control takes effect. At this point I measured 60 ° C at the lamp head. It regulates up and down about 6 minutes to avoid the temperature coming into the critical range.
After approximately 12 minutes, the battery does not provide enough power to bring the LED to its maximum power.
The tests I have finished after 18 or 33 minutes because nothing has happened and I was afraid of my unprotected battery.”
Thanks for that link! Good to have the test data and charts. I was always a chart/data nerd.
