Transformers make it possible to power and operate low voltage lighting systems by converting your home's 120V line voltage power feed to the lower voltage (usually 12V, sometimes 24V) that low voltage lighting is designed to use. Indoor transformers are designed and rated for indoor use only. Browse magnetic and electronic transformers for monorail lighting, softstrip, LED pendants, and other low voltage lighting. Choose from brands like Edge Lighting, Juno Lighting, Lightech, and more. See Outdoor Transformers.
