This is what I use to plan my LED circuits' resistance.
Awesome, a site that will draw me a picture! The picture is for DC, but it is a start. It leaves me with the following:
1) What input voltage do i use, considering I run conventional and will be running DCS with variable loops included? At 8 V my 2 30 mA bulbs call for a 68 ohm resistor, but if I go up to 18V it calls for a 470 ohm resistor.
2) What do I need to add to run AC?
3) How can the LED be made directional in AC (Tender tail light)?
Added after initial post.
Dale H's site clears up some of this (wow, you did a lot of work, thank you Dale)
