[QUOTE="i13, post: 115205, member: 21708"] The first one looks promising to me but maybe not the second one. The first one says 29V. I suspect that it is actually a 2 wire string and not 4 wires. Two wires probably go to a plugpack and the other two go to the lights. Am I correct? Regardless, I have higher hopes for this one. Knowing this detail will help me determine the correct type of controller for it. One problem with most light sets like this is that they each have their own plugpack and they can be slightly different voltages. When you convert them to computer control, you'll be using a central power supply. The options are to modify the light sets (my preferred option) or to have multiple central power supplies to accommodate the different voltages. Once you start modifying a light set, power it exclusively with a low voltage power supply. That removes the danger in accidentally trying to modify a 120V light set. Don't plug it in like you currently do. There's no use for the original plugpack once you start modifying. It looks like the second one is a 120V LED light set. The 3.3V LEDs would be wired in series to add up to 120V. [/QUOTE]

The title of our introductory lighting manual contains a three digit number. What is that number? Clue: Display basics forum
