About 10 years ago, I had an idea about designing a lamp, using LEDs (I'm an electrician). So I wanted to learn which colours to blend in what proportion to achieve a pleasant colour temperature and good colour rendering. This idea led me down an UNBELIEVABLE rabbit hole of colour theory. This subject is maddeningly complex, and I feel like I still don't know anything at all.

The LEDs are widely available in various "COB" (chip-on-board) packages that consist of a bunch of them wirebonded to an aluminium PCB. They're in series so they take a more convenient terminal voltage like 12V or 36V. Then you have to decide whether you trust the Chinese constant-current supplies or get a more expensive one.
