I am trying to design a LED light with a power supply of 12 volts 2 amps. I am going to use 6 LEDs total. I bought some 3 watt LEDs off of eBay and are rated at 3.3 volts 700 mA. I used one of the LED calculators to figure out which resistors I needed (2.7Ohm) but I also saw some that said to use a 3.3Ohm. I have them wired as shown but they are not that bright. Just out of curiosity I tested one of the with 2 AA in series to see how bright they should be and they are no where close. What have I done wrong?
I have also thought about rewiring them with 3 different circuits that have 2 LEDs per circuit.
