Описание к видео Autopsy of faulty LED lamp. 670 volt PSU! with schematic.

This rather interesting LED lamp was sent in by Mark. It had lasted about 30 seconds before failing with a dim flicker. The really weird bit is that this lamp has a 670V internal supply to drive a massive series array of LEDs.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
