Where can you get blue or white 22mm leds? Electronics goldmine sells green ones, digikey sells red yellow and green ones, and manufacturers make you buy lots of them. Question

I don't see any 22 mm LEDs at either digikey or goldmine-- can you point to an example?

apparently they are usually called 20mm (the diameter of the lens), instead of 22mm (the outer diameter)

Yes, I saw both of those-- but those are the 20 mm types. This is (generally speaking) an obsolete format-- designed to replace lenses over big incandescent indicator bulbs on instrument front panels.

Ledtronics has these in blue and white-- exactly what you are looking for, but with a (reasonable) minimum order requirement. Their distributors may have them in unit quantity. Anyway, my advice, unless you really have a good reason to do otherwise: Use a smaller (e.g., 10 mm) LED under your own separate diffusing lens. You'll have a much easier time sourcing this, and it will probably cost less.
