I received a request from my brother to fix this flashlight. All I have to do is replace the LED. I use AliExpress to find parts for this flashlight. after all, it was easy to fix, but be careful, it's a catch!
I ordered the LED with the whole PCB because it can be replaced faster. Protmas can also change the LED itself by desoldering from the original PCB, however I trust the factory SMD soldering.
!!!--- Safety first, don't shine this LED in your eyes as it can cause blindness! Be very careful ---!!!
