Hi all
This is sofirn if23 pro torch and one part of main led is always on like poor moon light despite of device is off.
I tried 3 different battery and directly type c cable plugged without battery but problem still exist.

Problematic led part also flickering sometimes.

Is there anyone else who has had same problem and solved it?

Thanks

I received an IF23 Pro earlier and also encountered this. I’m not sure when it started happening, but I noticed it after some testing at night. Some searching online suggested reflowing the emitter could help, but I’m not sure - it feels like like even when “off”, the driver seems to be supplying the tiniest bit of current to the front emitter…

Unfortunately, I couldn’t find a fix for it. At the moment I’m periodically checking battery voltage to see what kind of long-term effect this would have on battery life.

Try cleaning threads, etc, as good as you can. I always use a piece of cloth with a BIT of aclohol, then a rerun with a dry piece of cloth. FYI, if possible, I always physically lock-out my lights when not in actual use (eg. holding in my hand).

Oh, looks familiar

I still have not dared to extract the driver.

I am concerned about LED life, that’s why I unscrew tailcap. Battery will be fine.
