Inside a big pink lamp (with schematic)

I had high hopes that this lamp may actually have used LEDs that had their output colour chosen to match the cover for maximum efficiency. But alas no. Just like the old tungsten lamps it uses white with a subtractive colour filter.

In modern terms the circuitry is quite old fashioned too. The new standard seems to be for simple linear current regulators with enough LED chips to match the mains supply voltage.
On a plus note, it does mean that this light is suited to a wider voltage range of about 80V to 240V.

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