I use the LED Wizard at http://led.linear1.org/led.wiz
Where you don't know actual values, click on the question mark and it will give you suggestions. LED voltages run from 1.5 to 4.6, You can place them in series for higher voltages. Or combinations of series and parallel for more LEDs. Four 3.3v LEDs in series is almost just right for 12V. LEDs require current limiting resistors. The LED Wizard calculates that for you. LEDs can be purchased with these current limiting resistors built in for a specific voltage, like 12 volts, and are called LED assemblies. Radio Shack sells 12V LED assemblies as well as regular bare LEDs, On Saturday, January 3, 2015 6:03:37 PM UTC-6, Bert Knupp wrote: > > Volks, > > Just curious.
