So with proper resistor selected you can as well power the same led from 3V power supply, as 100V. Very long answer: http://forum.free-track.net/index.php?showtopic=700&message=5339 Try reading the post linked above. If it doesn't help, it will be the best to use the LED calculator on the main page, and build your circuit exactly according to the schematics and values given by the calculator: http://www.free-track.net/english/hardware/calcled/
