I've got a little led cob light that runs great off of 5 volts, I'd like to run it off of 12 V by changing the resistor. It's 4.1 ohms. What value resistor should I put in place of it to run it at the same brightness at 12V? If you don't mind running though the math, what equations are needed to figure out something like this?
