OK, so we're already looking at leds emitting @ 420,430,525,680 nm anyway.

Not all photomediated responses are gonna be wavelength determinate- We're gonna need to determine which are , and which will need to otherwise managed.

I'm also wondering about availibility/cost of leds tuned to these precise wavelengths- wondering if it makes sense to build in some slop ie leds @ 655 & 665 instead of 660nm.

Seems like color temp variations could be managed by switching-

know nothing about LEDS- are they voltage dimmable?

Still looking for more precise data.

Anybody got a Lexis/Nexis account?
