NOTE:    If the results for Resistor value and power are a negative number, probably the value that you entered for the “Source Voltage” is less than the total for “Number of LEDs x LED Voltage(FV)”. In this case, we recommend you to increase the Source Voltage up to over until you get a positive value for Resistor and Power.
