I plan on running 2 green Crees in series with a forward voltage of 3.58 each on 7.4v battery. When I input my numbers to calculate a resistor into http://led.linear1.org/1led.wiz im getting a warning that my forward voltage is suspiciously high.Should I be concerned with the setup or will i be okay?Also, LED wizard recommends a 1ohm, 2w resistor for my setup. Should I try a different resistor with a higher ohm?For reference im inputting 7.4v battery source, 7.16 forward voltage, and 1000 ma
If you up the resistance, you are essentially lowering the current available and they will not be as bright. Is there a soundboard in the mix, or is this a stunt?
PC 1.6's do not require resistors for your blade led, the board has a built in current regulator for that. You can adjust the current in the configuration file, or if you have it, RICE. You will only need a resistor for the foc led.
