Been out of luck with my recent flashlight purchases.
First came a MF01 with a single Defective LED from Banggood.

I’ve then purchases 2 sets of dx80 from GearBest.
Clarified with Imalent that these are indeed Gen 2 sets as the Gen 1 sets had some issues.
Both came DOA!
First light out from the box, OLED screen not working.
Well least I had another one which was perfectly working, so as i thought until i looked at the LED when the light was on.
2 LEDs are only half lighted up.
Is this supposed to happen?
The LEDs on the set with defective OLED screen seems to have one half lighted XHP70.2
With Sticker on – Set with defective OLED
Without sticker – set with working OLED

Man I’m so sorry to hear… Can’t believe you got two, and both of them have issues. Half of the emitter lighting up is a typical gen1 issue (before the recall). Have you contacted the vendor or Imalent?
One was an intended X’mas gift for a buddy.
I’ve contacted Imalent regrading the defect, and verified that these are Gen2 sets.
Imalent suggested that i contact Gearbest for returns.
But as we all know Gearbest After sales support = No reply until a paypal case is lodged.
Been almost a week still no reply from GearBest, will escalate the case by the end of next week.
You could contact member CSgearbest first before starting a Paypal dispute; maybe she can help.

Thanks for the heads up! Will contact CSgearbest.
Hope the exchange can be done before X’mas which is highly unlikely.

Have you checked if the LEDs light up completely in the higher modes?
Large Cree LEDs aren’t guaranteed to work at very low currents. It could be normal behavior.

Lowest output of DX80 is about 100 lumens, so roughly 10 lumens per XHP70.2. Isn’t this more than enough to light up completely?
Nope, official minimum is around 170-180 led lumens per LED (105mA with 12V config).

I’ve tried looking at 500 lumens & 1500 lumens with a Camera ND filter over the light, partially lighted as well, for turbo at 32,000 i’ve not tried , will be blinded!
And what did you see?
You could also try using your camera with short exposure.

Make me hesitate to buy DX80. What could cause it to light up half led?
It’s random because of production tolerances.
It makes no difference in actual use when you have this many LEDs.

He will let you know as soon as he can see the keyboard again
Will try using a taking a pic of the LED at turbo tonight.
I’m pretty sure these are the same items recalled from the Gen1 DX80.
For both pieces to have QC issues, thats worrying.
So far no reply from GearBest CS after a week , whatever happened to replies within 24 hours.
PM CSGearBest and told to email support@gearbest.com which they dont reply.
Imalent did however ask me to ship the heads back which shipping cost will be covered by me.
they did mention that they will include an Imalent DM21T as a gift. But that defeats the purpose, bought one as a X’mas gift, but the time they receive my package and ship out , it will be 2018
Wont the half lit LED produce less lumens?
Think about how many led dies this flashlight has and how many of those are not lit up. You can’t tell the difference by eye.
It’s not imalents fault. The only way around this is using pwm.

If I’m not mistaken, the leds don’t light up at higher levels as well (#10).
Ah ok, I missed that part of the sentence. At 1500lm they should all be lit.

I bought my Imalent DX80 from banggood and initially it seemed fine and even the charger seemed to work for the first charge.
Then I noticed that 4 of the 8 LED’s had gone dim and were not lighting up in any power mode… Great…
Queue a dozen emails back and forth to banggoods customer service department…
Is the battery fully charged?
Is the head screwed on properly?
Send us video.
send us pictures.
Is it working yet?
Then in the end they told me to contact imalent….
Finally imalent said send the head back and we will exchange.
Shipping will cost a fortune and I already got shafted with import tax and might even get it again with the return head. (Hopefully sometime this year)
But the main question is.. Am I going to get another lemon?
Love the idea of this torch but not really worth the nightmare and building costs.
Has anyone got any good ones??

I got a good one.
It’s not really a practical light. About as practical as a Nitro-Methane burning funny car.
For me, it’s a light to have “just because”
My dx80 wont charge. Emailing back and forth with bang good is like pulling teeth.
Times like these are when i rethink buying pricey toys like this from china.
I ordered a DX80 from Gearbest yesterday but decided an hour later to cancel so I filled out their cancellation form. This morning I get an email that it has already shipped lol. I've read a lot about the DX80 and for most people it works just fine, but obviously imalent has some serious quality control issues they need to deal with.
Lol indeed. I tried the same with another much cheaper item before and got the same result. Those of you who want to get stuff shipped faster might try cancelling rather than that seemingly useless “dispatch faster” button.

agreed
mine has zero issues , hope you love it as much as i do
Imalent DX80 currently on sale at GB (MAP =$379.95) $216.00 w/code. Why so cheap if so good? Many times, flash sales, I think GB sell known flawed products.
>>>Searching for a specific flashlight? <<<
I sure hope not, I bought one….
Sometimes a good price is just a good price
I'm going to ask Imalent if they can help me repair mine or what to do about it as GearBest won't allow me to make a claim. Everytime I try and send a claim, a pop up comes up and says to check the product and won't allow the claim. Some much for every ordering from Gearbest again.
