Yes, mostly true. I’ve not been able to disassemble one of the bulbs as easily as shown, but the part about a single led going bad is absolutely true. The leds are connected in series like the old Christmas light strings where if one goes out, they all go out. You can see a couple of different manufacturers in the video and there are many more out there and they will all use different methods of powering the leds but identifying the bad one and shorting it out should work on any bulb. I haven’t tried wrapping a wire around the bad led as shown but should be ok, soldering would be better. The bulb he was working with had a fuse in bottom section covered with heat shrink tubing which will blow if something goes wrong, otherwise you could start a fire or get shocked when messing around with these things. The guy in the video didn’t take the time to point out the safety stuff, so be careful if try this.
