The 4426 Base Mount (BM) LED underwater landscape light, available in 44- and 86-watt configurations, provides exceptional lumen maintenance and optimized energy performance for fountains, water features, and waterfalls. This versatile underwater fixture is suitable for wet or dry applications, making it ideal for areas prone to fluctuating water levels, such as waterfalls, streams, and ponds, where underwater conditions may occasionally be dry. The 4426 accommodates both monochromatic LED arrays and RGB arrays, enabling dynamic color control via DMX protocols, while RGBW configurations are available as custom solutions. An integral yoke allows precise fixture aiming for optimal beam placement, and the fixture is offered in natural cast bronze, saltwater bronze, or stainless-steel finishes to suit aesthetic and environmental requirements.
The light source consists of either dynamic RGB LEDs or static monochromatic LEDs, with lumen output up to 10,985 lumens. Color temperatures include 2700K, 3000K, 4100K, 5300K, as well as amber limited wavelength, amber phosphor-corrected, blue, green, red, and RGB options. The CRI is rated at 70, and the fixture supports forward phase dimming for flexible lighting control. Light distribution patterns cover a wide range, including flood, horizontal flood, horizontal spot, medium flood, narrow spot, very wide flood, and wide flood, allowing highly adaptable beam shaping for various landscape and water feature applications. Fixture wattages are 60 and 96 watts, and voltage options include 120V or low voltage configurations.
The 4426 is constructed with heavy wall cast bronze, including the fixture housing, rock guard, and base, ensuring long-lasting durability in underwater and wet environments. The base incorporates two 0.28” mounting holes for secure installation using 1/4-20 bolts (supplied by others). The LED arrays consist of 18 LEDs for the 44-watt model or 36 LEDs for the 86-watt model, with options in 3000K, 4100K, or 5300K white, or monochromatic amber, red, blue, or green. All LEDs are within 3 MacAdam ellipses for consistent color output. The lens is clear flat tempered borosilicate glass, and a single-piece molded U-shaped silicone gasket ensures a watertight seal. A minimum 10-foot submersible rated power cord (#16/3ST for standard 120V AC, 14/3 for CSA compliance) is provided, with epoxy encapsulated cord entrance, and cord length must be specified to accommodate installation needs.
For quality assurance, all 4426 fixtures are factory leak tested at 10 PSI (0.70 kg/cm²) while fully submerged. Stainless steel fasteners secure all components, and the fixture complies with cCSAus wet location requirements. Government procurement compliance includes qualification under the Buy America Act (BAA) as a domestic end product, as well as the Build America, Buy America Act (BABA). This ensures the 4426 LED underwater landscape light is suitable for both aesthetic and functional applications in fountains, water features, and other architectural aquatic environments, offering reliable performance and precise lighting control.
