Prototype mains LED lights

Exploring some very early prototype LED panels from when gallium nitride LEDs first appeared on eBay (the dumpster ones!) and made projects like this viable.
I also appear to have inadvertently predicted the use of large arrays of LEDs with simple current limiting as used in modern lamps, albeit with each LED containing large numbers of separate LED dice.
Perhaps I should revisit this project and add a two transistor regulator for stable current regulation on bumpy supply voltage.

I like the idea of 3D printing a custom housing too.

If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

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