The Vevor low voltage landscape transformer is designed to power outdoor lighting systems with stable 12V AC output from a 120V AC input. It features three independent output groups, a built-in 1-12 hour timer, and an external photocell sensor for automatic dusk-to-dawn operation. Its rust-resistant metal housing is built for indoor or outdoor use in demanding conditions. The transformer operates quietly and is suitable for spotlights, pathway lights, lawn lights, garden lights, and pool lighting.
