Once again thanks,
I have used various resistance calculator etc etc which is what origonally brought me to ask the question is a resistor needed when running within the allowed supply range 3.0v - 3.6v in this case. As the calculations come to 0 at the correct supply voltage ie -
3.3v - 3.3v = 0v
0v/30mA = 0 ohms
Some calculator automatically round the value up to 1 Ohm as being the nearest value to 0, other just say 0 !!
I have been assured by one of the suppliers of the LEDs that no resistor is needed for the LEDs if they are to be operated strictly between 3.0 - 3.6 v . But again this is just another view!!
