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 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.
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.”
Admittedly, that’s also the only Imalent light I own, the DN70, so not a lot of experience. However, that little light has been a workhorse for me, and I’ve enjoyed it.
Cheers!
TBH me and many others with a fully functioning DT70 think it’s the best high output light out there.
It throws brilliantly with a beam that seamlessly blends into the spill tricking you into believing you have a 50,000 lumen flooder. …and the tint is great. Many wanted a 4,000 lumen mode but tbh the circa 1,200 lumen mode lights up your path sufficiently with a long run time. Behind that reflector the DT70 is Noctigon Meteor sized and would warm up pretty fast with 4,000 lumens. Because of the BRIGHT hotspot the DT70 competes with a 4000 lumen flooder anyway imo.
Hey how are you doing man? I’ve read all your posts on CPF, and you really convinced me regarding the DT70. The relatively deep reflectors combined with the sliced emitters result in an awesome beam (tint as well). I do also believe that at the same time the DT70 humiliates other respected lights when it comes to beam profile. Maybe someday… Until then, all eyes on the DX80. :+1: :partying_face:
