FAQ:

Q: How many LEDs can you run on 12V DC?

A: Rule number 2 from the series circuit bullet points proves that 12V dc isn’t enough voltage to run all 9 LEDs in-series (9 x 2.98= 26.82V dc ). However, 12V dc is enough to run three in-series (3 x 2.98= 8.94V dc ).

Q: What type of circuit should I use to run high power LEDs?

A: The requirements of a lighting application often dictate what type of circuit can be used, but if given the choice, the most efficient way to run high power LEDs is using a series circuit with a constant current LED driver. Running a series circuit helps to provide the same amount of current to each LED.

Q: What is the minimum required input voltage to drive an led?

A: The sum of three of these LED forward voltages is equal to 8.85V dc. So theoretically, 8.85V is the minimum required input voltage to drive this circuit. In the beginning, we mentioned using a constant current LED driver because these power modules can vary their output voltages to match the series circuit.

Q: How many ohms do you need for 3 volt led?

A: Simple Basic LED Circuit Step 1: 3 Volt Basic LED Circuit With 10 Ohms Resistor. The above diagram shows a 3V LED circuit, in this circuit there are two AA cells are used. When you are operating an LED with 3V you have to use minimum 10 ohms resistor .
