Aquascape Color-Changing Fountain Lights are developed to provide an impressive accent to fountains, connecting easily to the top of the fountain with an integrated barbed fitting. The color-changing diodes provide a wide variety of color options, and the integrated white diodes provide a warm white light when desired. These low-voltage lights are extremely energy efficient and include professional, weatherproof quick-connect fittings for quick and easy installation. The Aquascape Smart Control Hub is required to operate the Color-Changing Lights (#84074 not included) along with a 12-volt transformer (not included).
