I recently received the Imalent DT70, three of the four LED’s work, one is dead. I had it tested in a well known calibrated sphere and on Turbo was putting 9,000 lumens out the front, this is with only 3 of 4 LED’s… unfortunately this defective light has been very frustrating and a lesson learned. No one will repair this light, not even some of the most recognizable modders…Return shipping ranges from $65.00 USD up to $175.00 USD !!! I would not recommend purchasing any Imalent light. They do a very good job of giving you the run around in hopes your PayPal escalating deadline quietly slides by…
I have pictures in the Dealers category.
Did you contact the store you bought it from about it being defective? Sometimes they will fix the problem. Refund or replacement. Nevermind, I see your in talks with Banggood.
Or did you contact imalent for warranty work?
Your situation is what I worry about from other Chinese only companies that do not sell replacement parts for their lights. With companies like Eagle Eye and Convoy I can buy parts easily and fix it myself. Having to ship a light back to China, on the other hand, can be quite expensive.
Did you explain your problems dealing with Imalent in a thread? I’d like to learn more about how they treat their customers.
So far I’ve heard people say that both Klarus and Olight ignore warranty claims. Are there any companies that take care of their customers?
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.
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 ………
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:
Nitecore Tip CRI

Turbo 636 lux - 629 @30
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.
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
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.
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.
