I'm installing a line of outdoor low voltage lighting using a 600 watt (300/300) transformer and a 12 volt line. Part of my line goes to two pillars I've built in which I'd like to install a nice pillar light. I can't find a "low voltage" pillar light I like. Can I use a regular 120 volt light fixture with a low wattage bulb? It seems that the selection of post lights in the 120 volt range are a lot nicer. With my two pillar lights and the six other lights installed on that line, I'm well below the 300 allowable watts. Thanks in advance.
