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. Please Note: Aquascape LED Color Changing Lights require a Smart Control Hub (item # 84074, sold separately) and a low voltage transformer (sold separately) in order to power and control the lights.
