MANY Multiple color LEDs. Too much?
<< < (2/2)
BobA:
1. Check your 12V amp rating.  Most supplies have more than enough to power a couple of amps for 12V LEDs

2. The resistors are set for your LEDs to run on 12v.  They should all run quite well off 1 12V wire but you can use more than one 12V lead if you want.  The telling factor is the 12V lead.  If it is warm use more than one to split the load. They all come form the same 12V in the supply.  The extra lead just beefs up the amount of copper in your 12V feed to overcome any internal resistance.


3 the resistors should be sized for the different colors so they are safe to use on a 12 v supply

4 not sure what you mean by daisy chain.   If you mean like daisy chain the ground on switches yes you can do that with the ground and the supply as long as the LEDs are all oriented correctly.

BobA, you're one of the most technical and helpful guys I've seen on these boards, and you came through for me.  Thanks a ton! :applaud: :applaud: :applaud:
