Frequently Asked Questions (FAQs)

1. Can low voltage transformers be mounted outdoors?

Most low-voltage transformers have their own mounting systems, so you can attach them to stakes outside your home. These transformers also have weather-protection seals, but it's still a good idea to cover your outlet to keep moisture out.

2. What type of transformer is used for landscape lighting?

A low voltage transformer is at the heart of every landscape lighting system. It converts 120 volt current to a low voltage current (between 12-15 VAC).

3. How many lights can you put on a low voltage transformer?

A typical halogen lamp is going to need 20 watts of power. A 150 watt transformer can only support up to 150 watts of lamps. This means the most you could add onto this transformer would be 140 watts, or 7 halogen lamps.
