So I'm getting in some new LED's, they are reported as 20 Watt RGB LED's. DC Forward Voltage (VF): Red 13-15V, Green 18-20V, Blue 18-20V DC Forward current (IF): 600MA I am new to most electronics with a very minor background. Originally I was looking at putting pots on them (then realized they won't hold that much) then looking at dimmers from home depot (treating the LED's like bulbs in a house, but that's 120 v next looking at transistors, but not sure what I would be looking for. I think one of 15v for red and two for 20v for b/g and have them rated for 0.6 A. then someone told me to look at mosfets, but if I'm not mistaken those are on or off, (dimming is a must)
so with all this cluster of n00bism, I'm turning to the internet for help!
