I have 13 lights with 12 volts 35 Watts on each light for each tree, the outlet is 120 volts current now. Should I buy 300Watt or 600Watt low volts transformer to supply all lights? Need your advise!
So how much do you think 13 times 35 watts is?
The minimum transformer you need, with 80 percent safety factor, and internal inefficiency, is 500 W, so get the larger one.
you need to drop lights down to 25 watts ,and use the 300 , the 600 is just 2 300s not a solid 600. check out malibu lights web site.
you need a transformer that will support the 12volts lamps and still connect to the 120volt outlet. the best suggestion is to go to the Radio Shack and talk to the counter dude for help --- or --- go to the garden lighting section at Lowe's etc, for
