Hi guys, my Emisar D4V2 keeps turning itself on. It even switches itself to turbo instead of stepping down, resulting in blisteringly hot body. I’ve caught it on video here https://youtu.be/3IhSXOHPtf0
It turns on to full output, slowly stepping down as it heats up, then suddenly switching to turbo at 00:50. At 1:30 the light starts to smell. If left unattended it would explode/catch on fire as it wasn’t self regulating. Button didn’t work, I had to unscrew the tailcap to turn it off, burnt my fingers doing it.
I ordered the light on September 16th 2019. I’ve been using it with a 18350 battery exclusively without any problems until this weekend. I’ve never put it into muggle mode.
After installing a brand new, fully charged 18650 battery (Sony VTC6) it turned itself on after sitting in a backpack for about 15 minutes. Button didn’t work. The light started to work ok after sitting with the tailcap loosened for about an hour and cooling down. Turned on again on its own after about 15 minutes on low, ramped very fast to high, then down to low, then up again and stayed there. This kept repeating every time I left it sitting with tailcap tightened.
I went back to 18350 battery and it seemed to work ok again for over 2 days.
Today, it turned on in my pocked (with 18350) and managed to burn my leg before getting it out.
Does anybody else have similar experience? Is this something that can be fixed with a firmware update? Is there any other solution? Factory resetting doesn’t seem to help.
So far, I’ve sent 4 emails to Hank, first one couple days ago, with no response yet.
Any help will be much appreciated.
Thank you!
