So after reading the FAQ I found LSDiodes.com. Great place, got my LEDs. I have one simple question. They give typical and max values in their specs chart. Which numbers should I use in the equation to find what resistors I need? Would I use typical or max? Average of both, I dunno. Thanks.
Here's a link to the specs on the ones I got by the way.

Oh, and you use Max
Also, how many in each string of LED's? That will change the resistor value.
OK, cool, I had a sneeking feeling max was the safe bet. That link is from the FAQ as well isn't it? I know I ran across it, as well as crunching numbers manually, in my research on this. I'll be using individual LEDs on individual 12V sources, so the math is easy. So long as you know which numbers to use. thanks again for the quick responce.

Nah... it's a link that I have had bookmarked well before the FAQ was written... (apparently I'm one of the LED guru's around here

)
I had a feeling that you would be using single LED circuits... so here's the values...
Above and beyond dude, thanks.
