If all the LED’s are in parallel then it would have to simply be a lose solder going to one of the 4 LEDs. I would think it would be not too complicated of a fix. Getting to the LED’s may be a different story. Your neighbor over there likely not looking for a fresh can of worms to open. That’s too bad if you’re left little recourse for amending the situation quickly. I know that crap’s frustrating. I just put in an order this morning too. I’ll see how those dice roll.
The video is back up.
Here’s yet another video of a malfunctioning DN70.
Thanks for posting these issues.
I recently ordered the DN70 so these videos aren’t sitting well with me at all! :person_facepalming:
However, GB did take an extra 10 days to start shipping it so maybe they got in some newly revised stock that addressed these issues? dunno.
I’ll post my impressions and any problems encountered when I’ve had the chance to play with the light.
Here’s a good review of the DT70 by Charles BridgTec.
yeah, i had high hopes when they came out also
todds not the only one that ive heard of having issues
there have been several others
bad thing is how they are handling it
only takes 3 or 4 people with their dander ruffed up these days on the innerwebs, and a company could loose multi thousands of dollars
seems they would learn that ………
New review of DN35 here by Charles BridgTec.
Having a lot of fun with my DT70, it’s definitely 15,000+ Lumens on turn on but ANSI would struggle to get that unless they measured it in Greenland. Here’s how it compares with my other small lumen monsters:
Comparative ceiling bounce measurements:

Seriously impressive performance. Unbelievable how it humiliates the Thrunite… Also nice to see the more balanced beam profile with dedomed emitters… Thanks a lot for the video. 
The Thrunite TN36UT NW’s output is no where near the claimed specs of the CW version.
2400ish lumen DQG hits 271 lux and the TN36UT on it’s 2500 lumen mode hits 205 lux. Fully charged hq cells and different bounce locations yield the same results.
The DT70 just kicks arse on all its modes, but I do believe they tested it in a cold environment to get high ANSI figures as it gets hot and loses efficiency fast. 1600 lux to 1450 lux in 30 seconds in my 15c kitchen. Be interesting to do the same test with the X45 and X7vn.
Perhaps nobody knows Imaplent … 
Nice video comparison, KG_Tuning
I think the problem here is the battery.
If you watch the video, at some points, voltage readings pop up on the display. When he first switches to 2500 lumen it is 3.51V and sinking fast. A moment later it is 3.48V At 3800 Lumen it would be even less as the load would probably be twice that of 2500.
I had to download the youtube video and afterwards I was able to capture this still from the video. At the point when this light was in “3800” lumen mode but was in strobe mode, the voltage was only 3.36V
Are you telling us this information or telling the guy in the video?
Tell him and if that fixes the issue, come back and tell us. :+1:
My voltage reading is usually 15v out on my DT70, if it says 3.95 on the torch the batteries will read 4.10 in my charger.
On my DN70 the reading is 0.18V below the right value in the whole range except at above 4V, where it’s 0.15V below. Fortunately the error is nearly constant so it’s easy to correct. I checked with an Agilent voltmeter.
The voltage reading is very important because high/turbo output drops significantly when the (real) voltage drops to about 3.7V. This is typical of high output flashlights, not only the Imalent ones. The voltage measurement is a very nice feature of these flashlights.
On my DN35 the reading is 0.07V above at mid-range. I didn’t have the opportunity of checking at other values yet.
I am telling you guys
The title of this thread suggests that these Imalent lights are being shunned, for whatever reason, on this site.
I just want anybody reading this thread to be aware that this video could be unreliable.
To those that measure voltage with the light, I would guess that could be done only when it is on?
How does the voltage compare to a DMM with the light on in the lowest possible mode.
Also don’t forget that the voltage reading in the light is during a load AND includes voltage drops due to contact resistance etc.
I have an interest in this thread is because I would very much like to buy a DT70 and I am trying to discern whether or not I should.
I have 4 Imalent's now... well 3, I gifted one of them.
I have both the DN35 and the DN70 also have the DM21T.
I take the DN70 almost everywhere I go and , all three get a good amount of use. So far I had only a very minor problem with my first DN35 that was fixed in just a few seconds no tools required.
I think they are great lights. For the size you get a huge amount of light, and yes the Turbo even pretty short but it was never designed to hold that setting for a long period of time.
They company is still very young and they are going to have issues fro time to time. All new lights usually have their fair share of issues.I can name some major brands that have been around a long time that have just totally embarrassed themselves. No need to call them out because it was issues no one expected based on calculations. The issues came up in real world use.
If I begin to have problems with any of the three Imalent light I have I will of course post them but, so far I have none to post.
I do however have one thing to post about Imalent. After testing, I suggested including a spare USB cover. I got an email not long ago stating that they agreed and that future batches would be shipped with a spare USB cover. Not sure when that will begin but, my point is that when I contacted them they seemed pretty open to suggestions.
I will updated if anything changes.
Some people avoid them because they have a high rate of defects compared to other brands. The worst part is if you do get unlucky and receive a bad light, Imalent will not take care of their customers. You may as well throw it in the garbage and buy another brand because it’s a total loss.
