One day I was driving my work vehicle and felt a warm sensation on my side, I immediately knew what it was and ripped the EDC27 off me, turned it off and put it in front of the AC vent.
Unfortunately Nightcore designed this flashlight with a plastic lens which has melted slightly due to the heat generated in my damn pocket. I noticed this but didn’t think anything of it.
Later that day I tried testing the light out and to my dismay, turbo mode and the 1000 lumen light setting would only come on for a split second then switch to a lower light mode (I tried doing research but nobody seemed to have this exact issue). This led me to believe that the entire flashlight overheated and fried the electronics or something.
I took the EDC27 apart to try to inspect the internals for damaged parts. At the same time the lens fell out and I accidentally pressed the turbo mode button. I was surprised to find out that Turbo mode and all light modes worked like they did before. I then put the lens back on and tried again and sure enough turbo mode and 1,000 Lumen mode would NOT work again. This leads me to the conclusion that the altered plastic on the end of the lens is triggering the safety mode that was designed to prevent flashlight overheating in the first place which is ironic because it did not work when I needed it too. But it sure works now that there’s a little melted plastic on the lens.
As a solution I’m going to try to buff the lens with a dremel and reinstall it. If this does not work I will run the light with no lens as this is an option as well. Either way is the solution to restoring functionality in this case.
In conclusion if turbo mode or high output Lumen modes do not work on your Nitecore EDC27 and possibly other models of Nitecore flashlights, lense imperfections can inhibit the proper functionality of your light. This possibly includes melting, scratches, marks, dirt, lint, etc.
Lastly, use the damn lock function on your light if you carry them. These fuckers are dangerous😆

I wonder how would Nitecore react. I would expect them to send you the replacement flashlight as it was a failure of the safety mechanism, apparently.
Could be enough to put a small piece of black tape directly on the sensor. Often these are simple light sensors that respond to the intensity of reflected light.
