Alright,again thanks,i think i'm slowly getting my head around it all.I see now that running 3 LED's in series is the most from a 12V supply as theres not enough volts to run more than that.I also get i think,that the resistor for 3 LED's run that way needs to be for the 1.8V that is left over.Still not sure about the Ohms part but i'm getting there.
If i'm lucky then those LED's that are coming will infact have a resistor already included in that wiring,although i can't see one in the picture.If they do have a resistor then my understanding from all this is each one will have a resistance for the 8.6V that is not needed from the 12V supply to run an LED and that's how they are selling them listed as 12V ones,otherwise they'd just be pre wired LED's?
Infact these could be listed as 9V ones but the resistor if i'm reading it right would be different,thats all.
So for 12 Volt's it's 8.6v and for 9V it'd be 5.6V even though the LED is the same one?
I just hope they have them resistors or then my next problem will be trying to find them also.So much for a Tandys shop being like they use to down here.Years ago you could get anything like this stuff off the shelf.Not any more,they carry FA these day's in that sorta stuff.Still,theres always the internet,it just more postage like everything else these day's.
