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. Aquascape Smart Control Hub (#84074, not included) and a 12-volt transformer (not included) are required to power and control the lights.
