Transformers are the Heart and Central Nervous System of a Low Voltage Landscape Lighting. The transformer provides the voltage to the fixtures that is necessary for them to perform.
There are two types of lighting systems: and . Line voltage simply means that your lighting fixtures may be plugged in directly to an electrical outlet or hardwired directly to a power source. The voltage that the light fixture needs is the same as the voltage supplied from your wall. Low voltage lighting systems require lower voltage to operate than the typical power source supplies. So, if the power source in your wall outputs 120 volts, low voltage lighting fixtures typically require an input of just 12 volts. That’s why you need a low voltage transformer – to convert the voltage from your power source to the amount your lighting fixture needs!
