The 4415 rectangular base or yoke mount submersible fountain and reflecting pool light is a versatile underwater LED fixture built for both wet and dry application and capable of delivering up to 726 lumens. Its LED static light source supports 3000K, 4100K, and 5300K color temperatures along with monochromatic blue, green, and red options, while maintaining a CRI of 70. The fixture operates at 15 watts and is available for 120V or low-voltage systems. Multiple optical distributions enable precise performance across diverse water features, including flood, medium flood, narrow flood, narrow spot, spot, very narrow spot, and wide flood beam patterns, supported by four primary distributions for simpler project standardization. The IP68 rating confirms complete submersibility, and each unit is factory leak tested at 10 PSI while fully submerged to verify long-term reliability.
Built for durability, the 4415 incorporates a heavy-wall cast bronze housing in a natural bronze finish secured with stainless steel fasteners, paired with a tempered borosilicate clear glass lens and a single-piece molded U-shaped silicone gasket. The fixture includes a standard rock guard for added protection in high-impact environments. Six LEDs driven at 615 mA deliver stable performance with a maximum power consumption of 12 watts, and lumen maintenance of the individual LED sources is validated through testing to IESNA LM-80 standards. A brass water-tight cord entrance with epoxy encapsulation ensures reliability, paired with a minimum 10-foot #16-3ST US submersible-rated cord for 120V configurations, with additional lengths specified as needed.
Several mounting approaches support varied installation conditions within fountains and reflecting pools. The ALB custom base enables placement of underwater fixtures exactly 2 inches below the waterline regardless of the fountain’s depth by securing the base in three points and cutting a 3/4-inch red brass threaded pipe to the required height. This design allows the fixture to be removed for re-lamping without disturbing the aiming position. The BM base mount provides a freestanding base with an aimable yoke for placement on the bottom of the fountain, while the YM yoke mount incorporates an aimable yoke with a through-hole for secure attachment to any flat surface. The fixture may be installed on the bottom or sides of the fountain, and riser stems from 4 to 24 inches in 2-inch increments (RSR6 if unspecified with ALB) further expand aiming control and architectural placement.
The 4415 is cCSAus listed as a submersible luminaire suitable for fountains, with laboratory testing conducted to UL 676 and UL 8750. Its suitability for both wet and dry installation enhances project flexibility, especially when integrating lighting control or synchronizing multiple monochromatic units within fountain shows, architectural pools, and reflective water surfaces requiring precise beam shaping and consistent color presentation. The fixture meets requirements for the Buy American Act (BAA), Buy America regulations under DOT, and Build America Buy America (BABA), qualifying as a domestic end product manufactured in the United States.
