Does a low voltage lighting system require the same amount of labor to install as a line voltage system?
No, a low voltage system requires much less in the way of labor. For instance, wire for 120 volt systems must be buried at least 18 inches in the ground and covered by a protective conduit, while wire for 12 volt systems only needs to be hidden. Maintenance costs are also decreased, as 12 volt lamps last far longer than the standard 110 volt lamps.
