Are they true orange LEDs?

Is "orange" the same as "amber"

So how do they make LEDs to shine a certain color?

If color is that important, check the data sheet -- it'll show at least
the peak wavelength, and usually an intensity vs. wavelength plot.

I'm not sure what culture you grew up in, but its being discovered that
your home culture and native language affects how you perceive color --
so your "orange" may not be the "orange" of the folks denoting the
wavelength.

Short story -- different dopant profiles. Long story -- google.

Thanks!

SO the discovery is just a trial-and-error process, rather than a
predictable, deterministic methodology?

Osram makes some really beautiful deep-orange LEDs. They are fairly
bright at 1 mA and barely visible at 1 uA.

I seldom see shops that are selling LEDs in Hong Kong to describe the
products in wavelength and frequency... :)

Sucks. You want to get what you need, do your acquisition correctly.

I'm not so sure Google is still our friend. Lately they've
been pestering me to agree to things I don't want to have
to agree to, and now they simply refuse service.

I can use duckduckgo. Google can go to hell.

Well, OK, fine -- I use ixquick and call it "google". But those few
times I do use Google (mostly for images, or so I can use lmgtfy.com), it
seems to work.

Not-so-bright orange is the new black.

Digikey lists LED's by wavelength, I think amber is close to yellow.
A while ago I was looking for LED's with a lot of light output. I don't
think Orange was a "good" color in that regard. (But I also might have missed
it.)
