Front Yard Lighting
Outdoor lighting systems are typically low voltage (they operate on 12 volts) and consist of light fixtures, a transformer, and electrical cable. Your transformer should be rated to handle at least 25 percent more wattage than the total wattage of all lamps on the system. For example, a system consisting of 12 20-watt fixtures (240 watts) will need a 300-watt transformer.
NOTE: Always plug the transformer into an outside electrical outlet fitted with a ground fault circuit interrupter (GFCI).
