As the others have or and implied, the short simple answer is "add a larger value resistor". All the ohms law stuff is for running a resistance (light bulb) at full brightness without blowing it out. You don't need anything that precise as an LED is not a light bulb. At the power levels we run, for a dim light, try a 5K resistor. If still to bright increase the ohms, if not bright enough decrease.Okay so I purchased street lights to begin adding to my layout...but they are LED and are way too bright for the look I'm wanting.. how in the world do you dim these things down...any help would be appreciated. I saw a post once about painting them...that didn't work.
Thanks for the help... yes the resistors did the trick.As the others have or and implied, the short simple answer is "add a larger value resistor".
