Home Â» What transformer size should I use for my low-voltage landscape lighting system? What choices are available? Transformers are available in 300, 600, 900, 1200, and 1500 watts. The size transformer you need will depend on the number of lights, wattage of lights, and length of wire run to the lights. Note that transformer sizing is not as simple as adding together the wattage of all the lights on a system to determine the correct transformer size.
