Transformers generally range from 150- to 900-watt capacity. Matching the size of the transformer to the lighting design is important for efficient operation and function of the system. House current, 120 volts, is reduced by a transformer to 12 to 20 volts, the current needed to operate low-voltage landscaping lights.
