with hanging the lights on the wire, lazyman uses cable to hang all his lights on..I'm sure he says how somewhere in his thread.
wow I didn't realize at first the scale and how many racks fit around each light. What size lines are those? 3/4 --> 1/4 ?
I've looked in lazyman's threads, and I see chains holding single lamps... I'm doing a 3 lamp light column, gotta run 2 lines, one on either side. Might just stick with chains for now...
Water lines are 1/2" to 1/4".
