General specs on LEDs:
Blue 3.6v
Green 2.1v
White 3.6v
Yellow/Orange/Red 2.1-2.2v

your motherboard i think gives up to 3.6v but regulates it as needed AFAIK

This is extremely wrong.

The color of an LED has nothing to do with its voltage.

counter me with some proof if you would.

thank you.

This generally refers to standard 3mm/5mm LEDs, but comes pretty close to the levels of the Luxeon LEDs as well.

i can't tell you what the amperage rating of the header is... so i can't say.

If you send your board makers a message they will tell you.

I wanted to know the specs of my fan headers so i just sent them a message and within a day they sent me one back explaining everything biggrin.gif

Yes you can. It's called parallel circuity.

It's...it's just wrong. Color of an LED doesn't have to do with anything. Color is just color.

That's like saying, blue power supplies generally are more efficient than green ones.

I have 20x LEDs or orange, white, blue, green, and yellow, and they all are rated at 3v.

i understand how to wire things in series and parallel, doesnt mean the header can take it though which was my question
