For my landscape lighting, I currently have three zones--that is, three "Malibu" transformers plugged into three GE outdoor Z-Wave modules. The setup works just fine, but it looks terrible. Big transformer and module hanging on the wall, with cords and cables dangling. Blech.
What I would like to do this spring is 12v distribution--install a 12v transformer centrally (at the breaker panel), and control it with one appliance module, smart switch, or some such Z-Wave device and then run 12v wire to the three zones. The load is small at about 18w, but I would like to add a few spots as well. I expect that a 60w transformer would be more than enough. Would make for a much simpler and cleaner install--and I'm guessing somewhat more efficient.
Has anyone done this? Are there any US electrical code considerations?
ps: relatedly, I've switched to these
Philips LEDs: and they work great. They're somewhat expensive at $6 but I feel they're the cheaper alternative because I'm not replacing 1 or 2 lights per month like I was with a cheaper alternative. They only draw 1.2w. Love them.
