Last night I tried 32000 lumens mode on my way back home holding the flashlight out of my window with the cool air blowing past it. In 6 minutes it didn’t step down from 32000 lumens. Very effective heatsink design. I probably tested for another 5 or 6 minutes at home taking some Beam shots and the battery was more than half full still. I’m loving this flashlight more and more every night.
For this kind of output, must do the throw measurement outdoor.
Else all the light get reflected from walls or furniture and give a higher throw candela number.
I am guessing Imalent made the measurement inside a lab else I can’t understand why they got the 32000lm correct but not the intensity.
I’m one of the “difficult ” guys; I don’t just buy stuff, haha! Seriously, I’ve been monitoring Imalent quite intensively for about a year when the DT/DN series were announced. Reliability is my biggest concern. Imalent told me yesterday they went for a different manufacturer after the first batch of DX80 failed… And this explains so much in my opinion. It’s not just stupid bright, but it’s pretty much spot on 32000 lumens according to spec. That’s unbelievable; even Acebeam lights don’t achieve this. So I hope Imalent finally found a really good manufacturer, and sticks with them.
I’m basically waiting for videos on YouTube to show up of faulty DX80 lights. If this doesn’t happen, there is my answer; it’s reliable enough.
Today I put a piece of heatshrink over the included metallic ring so as to protect the anodising,struck a match so as to shrink the plastic, and then I opened the tail cap and engaged the ring with some difficulty,closing the cap putting enough force.(Torque is better). Then I put the lanyard and it is OK.
I just got an email from Imalent and the eight batteries themselves don't individually have a protection circuit but the pack is protected. Here is what they said "It has one circuit but IC will check each group voltage"
I just registered on this site after a lot of time just reading posts and getting some great info. I bought several flashlights on you guys recommedations.
Last light I bought was the DX80 and it is phenomenal. Lots of fun to use. That is, until today, when half of the LEDs stopped lighting up. I read one post but he had half of the LEDs itself not lighting, on mine it is half of all the LEDs.
Do you have any thoughts on what I could do to troubleshoot it? Could it be battery issue?
I think the majority of blf members think that the DX80 is a risky purchase because of the driver problems.
If half your leds are not working then that also sounds like a driver problem. I don’t think I’ve seen anyone take the dx80 apart and show us what the driver looks like, so I don’t really know what the design is.
Have you recharged the batteries yet? Does it look like the charger part is working correctly?
If low voltage is not your issue then you will need to contact Imalent or the company you bought it from and see if they have some tests you can run. You may need to have it replaced under warranty.
Just a thought for later on. Couldn't the knowledgeable members of BLF suggest to Imalent a reliable driver for future production runs? I've emailed them back and forth a few times and they are very open to deal with and always email back promptly. If they decide to go with a good driver, this could be promoted on here and everyone wins.
thanks for your answer. It’s charging fine, and the lights did light up fine to begin with, but then suddenly stopped working. It stops charging at full icon and says 16.8v.
I have contacted Gearbest for an answer. I’ll see what they say!
What a fun light though, when it’s working.
The Imalent drivers are not the regular type we use around here. Their’s have digital displays that show the output and battery voltage. No one at blf makes anything like that.
I don’t even know what kind of driver they are using in the dx80. I’ve talked to Lexel in the past and his Texas Avenger based FET drivers can certainly handle the power of the DX80 going up to like 80 or a hundred amps, so that wouldn’t be a problem.
But I don’t think the dx80 is a direct drive light. They need to control the output a bit better. Maybe it’s some type of constant current design?
Terjef, Did you check the actually battery voltage with a multi-meter? I was asking a question today about how to check the voltage on the DX80 battery pack incase the OLED is not displaying it correctly or the charger is not working.
Here is a pic to do that. I copied and pasted this pic from the first page of this thread, so I hope nobody minds.
