Most users immediately notice that their aquarium appears clearer and easier to see, almost as if the tank has shifted into true high-definition. Coral edges become more defined, natural textures become visible, and the entire reef looks sharper from every viewing angle. Real Coral Response Coral results are often dramatic. Many hobbyists see colonies grow faster, long-term slow growers begin putting on new tissue quickly, frags heal faster, and corals produce colors they had never seen under previous lighting. Most aquaculture operations report major improvements within three months, often including completely new growth patterns and color expression. The Spectrum That Drives It The Meridian achieves this through an extended violet range from 400 nm through 440 nm, including true 440 nm indigo LEDs. These wavelengths support rapid tissue recovery, strong color development, and steady growth that limited-spectrum fixtures struggle to provide. Efficiency That Pays for Itself The Meridian is extremely energy efficient. In real-world comparisons with leading competitors, it has produced roughly 50 percent more PAR while using roughly 50 percent less electricity. This results in higher performance with noticeably lower energy costs. Modular and Expandable Multiple Meridians and Edge bars can run from one power supply, supporting up to six hundred watts of combined output while reducing outlet use and cable clutter. The system grows effortlessly as the reef grows. Flexible Installation The Meridian can be suspended, mounted to the back or sides of the aquarium, or integrated into a T track system. The Integrated Connection System links fixtures end to end, and Edge Articulating Mounts allow precise adjustments for complete coverage. Precision Optics The Ocular Holo Matrix optic system offers three optical profiles suited for different tank depths and aquascapes. Simple and Reliable Control The ReefBreeders app provides cloud based WiFi access, Bluetooth allows quick local adjustments, and the optional Manual Controller offers direct on-device control with smooth sunrise and sunset transitions. Built for the Long Term The Meridian is built for long-term reliability and long-term support. For reef keepers who want stronger growth, deeper color, clearer detail, and an energy efficient light that lowers electricity costs, the Meridian delivers that experience with confidence. Specifications Continued: 1 power input and 1 power output port for daisy chaining (larger power supply and cables required) Adjustable M6x1.0mm bolts on top of case Note: Mounting Hardware like side legs, back of tank mounts, and hanging wires sold separately. Front and rear tracks for mounting edge bars Port on top of light case for attaching manual controller 2.4GHz wifi control (bluetooth available soon) via ReefBreeders app Original LED Layout: The Original layout is designed for reef keepers who prefer the classic 20k reef appearance. It uses a strong blend of blues and violets with a unified white channel to create the deep blue look that many hobbyists enjoy. The whites are balanced to support the overall spectrum without washing out the blues, allowing you to raise all channels evenly and keep that signature blue aesthetic. A UV peak at 405 nm adds clarity and definition to the corals while maintaining the natural deep blue tone of the layout. The Original layout is easy to tune, visually consistent at any intensity, and works well with all coral types. Shallow Reef LED Layout: The Shallow Reef layout is designed to replicate the natural appearance of corals in shallow reef environments. In these areas, the light has a balanced blend of whites, blues, and violets that makes coral color and structure stand out in a natural way. To achieve this, the Shallow Reef layout increases the number of white LEDs and separates the 3.5k warm whites from the 5.5k neutral whites, giving you precise control over the tone and character of the tank. Adjusting these channels lets you match the subtle shifts seen in real shallow reefs without pushing the spectrum toward an overly blue or overly white look. The layout also extends deeper into the UV range with a peak at 390 nm, rounding out a spectrum that works seamlessly with all coral types. With individual control over every major color, the Shallow Reef layout is easy to fine tune and presents your reef exactly the way you prefer.
