If I want to cut a set of Big W LEDs in half, what type of wire do I use for the second half to make the extention back to the controller? Also on the first half should you leave the connectors on?
Some people use 7/020 4 core security cable. Here's an example from Altronics (seems to be on special right now), but there are other places that sell a thinner jacket (insulation) version.
Have been reading up on what people ordered from mysolarled, and was wondering why the lights are only 2 wires. Don't you need the common wire like on the big w lights.
You can get LED strings with varying number of channels. Usually, the number of wires coming out the end is the number of channels + 1. So a 2 channel string (like Big W type where every 2nd LED is on a different channel) will have 3 wires. The my-solar ones you saw were 1 channel (all on together) I'd say so are 2 wire. Make sense?
