Real simple.
Use RGB strip lights. You should get some at the China mall. About R60 per meter.
I used 5 meters of the stuff. They were cut in about 300mm pieces and soldered in parallel.
Every color is current limited by a 100 to a 200ohm pot that allows you to change the color temperature.
Power the light with a 450W PC power supply because its the cheapest form of a 12A 12V psu you can get. About R185.
Glue the assy together with Q-bond and use sash cord to hang it.

I will disappoint the authorities with my choice of herbs. Its some real good origanum.
