Do you guys know how reliable the led calculators are? Because I have 18 leds per strip wired in parallel and It says I need a 33 ohm resistor per strip running on 12 volt, but the last thing I need is to hook it up and it blow them out because I dont have any more leds left. This is the one I used to calculate it. Here are the specs Parallel wired, supply volts 12, voltage drop across LED 2.2, Desired led current 20 milliamps and 18 leds.
