Somebody help me figure out what’s wrong with my Blf A6. Noticed my lens starting to look a little foggy and there’s a black spot on my led. I normally turn the light off when it gets a little warm. Hope it’s not something I did. Still functions fine.
Update: replaced the star with led pre flowed because I’m a wuss. It was my first time doing anything like that. I know it’s stupid simple but still felt good when it worked thanks for your help. First baby step taken.
Insufficient thermal paste or ran too hot > LED and MCPCB overheats > Remaining solder paste or flux on the board is evaporated causing the fogging.
A small dark dots on the emitter surface normally means too much current or needs better heat sinking, sometimes it can be cleaned with some alcohol. (When it happens in a HI)
I would take the light apart and check for lack of thermal paste or bad reflowing job. Then run the light on turbo until it gets hot before assembling. I have seen soldering paste remains evaporating many times and fogging up the reflector, specially on the SMO ones.
Could just be flux and you can wipe it of easy?

I mourn the loss of my favorite flashlight. Glad I have a second one in a warmer tint that I just discovered I like better. Now I have my first emitter swap to do. I feel like a idiot but the hard way is the only way I learn unfortunately.
