New LED Lamp

[butterfly_muse]

While we're on the subject of lights, I was thinking of buying a few of Ray's LEDs for my guys over the winter. I have very few plants - only 9 in total (5 phals, 3 cattleyas and an oncidium intergeneric) that have different light requirements and will be in a very compact growing space. 1) How many lights would I need for each set of plants (3/5 phals are mounted, 2 are minis in a pot) and 2) I am still new to the light/spectrum thing so I don't really understand the different colors/nanometers/spectrum, etc. I know the basics, but all I want for the winter is to provide my plants enough light not to wither and die, and to allow them to continue growing. Will the LEDs do the trick or should I try something different? I am pretty constrained for space, so...

Sorry, I'm confused...^^;
