Does anyone have a link to a lighting spectrum chart

[Pixelfish]

I am trying to figure out the general required spectrum for orchids. I did not find an actual chart using the forum search feature here. I did however, find some controversy over LEDs which make me want to look at an actual spectrum chart. I believe LEDS would work great (But I know nothing about orchids.).

I have a very nice programable 24 hr LED fixture I used for a 2' deep salt water aquarium and it provided enough lighting at the very bottom to keep anemones happy. If these lighting fixtures are superb replacements for T5 fixtures in the reef aquarium, how is it not for orchid lighting?
