I have seen a low voltage lighting system used in a few commercial locations that I would like to gather more information on.
The lighting system resembles a knob-and-tube wiring system. There are two conductors (sometimes insulated, sometimes not) installed approx. 4" apart in free air. Low voltage heads are connected to and supported by these branch circuit conductors. The secondary of a power transformer supplies the two conductors.
Does anyone know what this lighting system is called. More importantly can you refer me to manufacturers of such. Thanks in advance.
