New LED lamp twist reverse engineered from a picture

Just when you thought they couldn't make an LED lamp simpler than the common linear regulator type, they come out with this.

It's basically a single package combining the rectifier and current regulator into a single package.

These lamps work by using enough multi-chip LEDs in series to approach the normal mains voltage, but then use a linear current regulator to keep the current constant by acting as an active resistor, with a small voltage dropped across it.

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