Ok, I know Im going to seem like an idiot but I cant figure this out. I mean this is as simple as you can get, so I guess Im having one of those moments.
Superflux LED 3.1-3.5v @20ma
12-13v I need atleast a (495) 560ohm resistor for one.
I calculated I could run 3 in series most likely 4, even though the math is off. So I wired in 3 and tested with 3.1v and they were still bright. I added a 4th and still bright, then a 5th and still bright? I did not, up the voltage and left it 3.1 volts. I tried a single at 3.1v and they are equal in light. What am I missing here, this should not work. I mean 12v should not be enough to run this many in series and Im doing it with 3.1v.
So with 5 in series I have 3.1v @110ma (.11a), so the milliamps make sense but the voltage does not. I know this is going to embarrass me somehow.
