news:460767a8$0$22762 You should not parallel LEDs and use one resistor
since LEDs might vary a
bit in voltage, resulting in uneven currents through the different LEDs.
You
can connect them in series, and add the voltages. So 5 red LEDs would need
a
total voltage of 5 x 1.6V = 8V. The added benefit is that there is less
voltage drop across the resistor and the overall efficiency increases.

Excellent post, I`ve filed it away, and now I`m an instant expert on
LED`s ;-)
Thanks.
