|  UTBEAMER.... LED shematic:
Here it is, I'd wire them this way, in parallel. That way if one wire breaks, or led opens the others will still work. LED's are polarized, that is must be hooked up the right way. Just wire one up as shown. If it doesn't work reverse it! Last edited by Ace; 05-10-2005 at 01:05 PM. |

Thanks Ace for taking the time and drawing that up. You have saved me (and i'm sure others) a lot of time and headache!

| Confused?
The way I see it, those LEDs aren't wired in parallel. The three bottom LEDs are wired in parallel, but as a group they're in series with the top LED.

4x4x4 is right, I had it all cocked up. I changed it. Thanks! |

Ah ha. It didn't look like it would work, but I was going to try it anyway. Mucho better.

Which gauge of wire do you suggest using?

...stupid question- what's the "470 ohm" gizmos on the hot side? Resistors? What do they do?

Wire can be anything. Current is not an issue. I'd use stranded for sure since it holds up to vibration better. Use about 18 or 20 ga. The resistors are needed with LED's. Led's are rated on current, if exceeded then they burnout. The LED's are based on Ohms law V=IR or R=V/I We have about 7.2 volts and typical LED's are .015 amps. So R=7.2/.015= 480 or more common 470 ohm. |
