The Aquascape 11-Watt Color-Changing Wide Angle Light is a revolutionary leap in underwater lighting that transcends the limitations of conventional spotlights. The heart of this innovation lies in its lens design, meticulously crafted to disperse light in a sprawling 90-degree beam angle, and strategically positioned beam cut-offs. The lower cut-off ensures an even glow, eliminating the intensity of hot spots that can disrupt the natural ambience. The upper cut-off prevents light from escaping upwards into the night sky, preserving the brilliance below the water's surface, and opening up additional installation locations. The design of this light further emphasizes the marriage of form and function. Its sleek, rectangular fixture not only aligns with contemporary aesthetics but also maximizes stability when tucked amidst rock walls. Versatility takes center stage with the inclusion of the Universal Mount Adaptor . This ingenious addition opens a world of mounting possibilities. Whether you opt for the stake, the flexible tripod, or integrate it with existing camera mounts and tripods using the 1/4" 20-molded in threads, the choice is yours. The Aquascape Smart Control Hub (#84074, not included) and a 12-volt transformer (not included) are required to power and control the lights. Create lighting zones or control separate sets of lights simultaneously by using multiple hubs, further expanding the variety of lighting options. An optional, Color-Changing Lighting Remote (#84073) is available separately, allowing for wireless control without the use of a smartphone or tablet.
