Brand: CAST Lighting | SKU: SUL20

Product Overview

The CAST Lighting Underwater MR-16 Light is a CAST Lighting underwater fixture for ponds, fountains, water features, and other compatible low-voltage landscape lighting applications. It is used when the project needs a fixture designed for submerged or water-feature lighting rather than a standard path, accent, or well light.

Use this model only where the fixture style, voltage, installation conditions, and product documentation match the water-feature application. Before ordering, confirm transformer sizing, cable routing, mounting location, and whether any additional installation hardware is required.
