So these folks seem to have a lot of choices, in a lot of wavelengths.
This is the page for the amber ones, which is what I searched for.
They seem to offer the same lights modified with a lot of different color emitters.
But, uh, I only read English.
And when I open the web page with Google Translate, it doesn’t help much.
Perhaps someone knows more about how to buy these, or can translate?
I don’t know if they’re good, I don’t know if they’re budget, but there’s far more of what I’ve been looking for here than anywhere else.
