Switching to LED but dumb as a brick and need help

Hey fellas,
I'm currently running my grow room with only fluorescent tubes and I'm getting tire of the heat and energy use. So, I want to switch over to LED and I want to do it cheaply. Can you guys give me an idea of what I should look for (light specs) and maybe where?
Thanks in advance!
 
Lumens are what the human eye perceives as bright light.
To the human eye, the color yellow is the brightest.

But Lumens don't work for plants. Plants hardly absorb yellow light, and if you give a plant 50,000 lumens in green light it will not grow very well at all.

Plants require light in the blue range and, foremostly red, deep red (and even far-red, bordering on infra-red) regions of the color spectrum.

A couple 4500K white LEDs in the mix wouldn't harm though, as these help filling up other wavelengths.

I get my LEDs (3 watts) and constant current drivers from Ebay.

Remember your main colors are red and blue.

Red - blue ratio should be about 4:1
Far red (660 nm) - red (630 nm) ratio 2:1

I'm adding 730 nm far-red, 400 nm UV, 1500K, 2000K, 4500K, 10000K whites, as these specs help cover the
entire spectrum.

Sofar my DIY LED panel experiments are working out quite nicely.
