The Atlantis 1407 is an ultra compact underwater fixture for use with a low voltage MR16 lamp. Its heavy-duty, adjustable mounting plate provides easy and secure aiming. A standard quick-release mechanism enables easy re-lamping out of the water. Various lenses, louvers and color or dichroic filters can be combined up to three at once to create multiple underwater lighting effects. The Atlantis series is designed for use in freshwater decorative ponds, fountains and water gardens. It is not suitable for use in salt water.
