Pondmaster 20 Watt Ultraviolet Clarifier - The only Ultraviolet Clarifiers with UL listed Submersible ballasts. Features glowing halo rings that show the light is working, above or below water. The black color makes it unobtrusive wherever it's used. Visible during the day and night from any angle, the soft blue halo shows it's working, but does not detract from the beauty of your pond. Designed to handle the clarifying needs of ponds. This light offers great value, along with ease of use unsurpassed by any other ultraviolet sterilizer. Mfg by E.G. Danner MFG
