Durable magnetic transformers from Light to Form are the ideal solution for powering outdoor landscape lighting and indoor low voltage systems. Converting 120V AC household voltage to 12V-15V AC multi-tap output for use with low voltage LED or halogen lighting, these power supplies are built with a heavy duty steel enclosure that will withstand the elements, operating reliably for many years to come. Our toroidal magnetic transformers are known for their reliability, lower operating temperatures, and energy efficiency, without the humming noise produced by electrical transformers.
