Information About Wire

  • Voltage always decreases with distance and temperature increase as electricity travels along low voltage cable.
  • The amount of voltage drop depends on the gauge of the wire, length of the cable, temperature and the load connected to it (total wattage used by the bulbs).
  • As voltage drops, light output decreases (and lamp life increases). AC and DC lighting systems use different size wires. LED DC wire is typically smaller but can use the larger wire.
  • Properly sized cables will cable typically will maintain incandescent light output within 85% of the bulb's rated performance and will maintain its color temperature within 5% of its rated temperature. LED lights can use smaller cable.
