LEDs - colors, wavelengths, and their effects on plants

Thanks for stopping by. I've been wanting to start up a thread like this for a while now about the different wavelengths and colors of light that leds can target and what effects each has on plant development. Feel free to post any information you have and I'll be posting some as well. Hope to get some good info here.

When I choose HID lamps the colour spectrum is represented with the CCT scale (Correlated Colour Temperature) - measured in Kelvins,
At 1500=3000k the colour is hot orange/red - promoting flowering
3000-3700k - warm yellow neutral - Highly active photosynthesis for all stages of growth (Duel Spectrum???)
3700-4000k - warm neutral - rapid growth
4000k - neutral white - normal growth
4000 - 5000k - light blue - good leaf/stem growth
5000 - 8000k - deep blue - excellent leaf/stem growth.

From what I have seen of LED's they don't use CCT Kelvins, they use Nanometres (nm).

Is it possible to change the thermal colour of an LED by means of 'graphic equaliser' type dials...???
Instead of adding a touch of bass and less treble - is it possible to 'reduce the red and increase the blue, ready for Vegetative growth....???

Or, like with HID's, different lamps are required for focusing on different stages of growth...?

Here's a chart with responses to specific Wavelengths (NM) and photosythesis. 420-500nm is used for strong vegetative growth, 660-700 is best for flowing and when used in conjunction you get what's known as the Emerson effect which increases photosynthesis dramatically.
Heres a link for the Emerson effect.
