mega ohms?
so im guessing the chap in maplin gave me the wrong ones?

Don't forget the power involved @ 1Amp they will be dropping 2.2v.
2.2v x 1Amp = 2.2W dissipated.

If I am understanding all this correctly, 4x 445nm diodes wired in series would need 4x 2.2 ohm 3 watt resistors. The first resistor in the + side wire going to the the first diode. The next 3 resistors inbetween each of the remaining 3 diodes, correct?
For a single 445nm diode use the same resistor?
