| (...) If the voltage is going to vary, don't use a resistor as current source, consider a current regulator instead. That way the LED stays brightly lit over a wide voltage range without getting burned out at max voltage. This works for one or more (...) (16 years ago, 24-Oct-08, to lugnet.trains)

For the DIYers out there: (URL) LED Resistor Calculator> For quick results without having to think: You can run 1 (2.1v) LED from 9v if you hook up a 390 ohm (1/4 watt) resistor between one lead of the LED and the power source. You can run 2 (...) (16 years ago, 22-Oct-08, to lugnet.trains, FTX)
