Introducing the ReefBreeders Meridian Series:

The Meridian was created with a focused purpose: to give reef keepers the strongest growth, the strongest color, and the cleanest overall look that modern lighting can offer. 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.

The Shallow Reef LED layout differs from the original spectrum by doubling the number of white LEDs for a more natural, shallow-water reef look. In addition, the 3.5K warm white LEDs are split off from the 5.5K neutral whites. This allows for more color tone adjustment, for example the warm white LEDs can be turned up for a warmer look, or the cool whites for a crisp appearance.
