Jump MJ-L230R LED Refugium Light Fixture - Maxspect

The Maxspect Jump MJ-L230R is a high-performance LED lighting system specifically engineered for macroalgae cultivation in refugiums. Designed with a sleek, minimalist aesthetic and professional-grade components, this light provides the precise spectral output needed to maximize nutrient export and maintain a healthy reef ecosystem.

Optimized Spectrum for Rapid Algae Growth

Unlike standard aquarium lights, the MJ-L230R (Refugium version) features a specialized "Hyper Red" spectrum. It utilizes 43 high-efficiency LED chips focused on the 660nm red and 450nm blue wavelengths. This specific combination targets the absorption peaks of chlorophyll-a and chlorophyll-b, fueling the rapid growth of Chaetomorpha and other macroalgae to efficiently scrub nitrates and phosphates from your water column.

Advanced Silent Cooling & Durability

The MJ-L230R is built with a full aluminum, matte-finished body that acts as a massive heat sink. Its passive cooling design eliminates the need for noisy fans, ensuring completely silent operation while protecting the internal electronics from the humid environment of a sump. The 90-degree high-transparency acrylic lens array ensures that the light is directed exactly where it’s needed without excessive spill.

Simple, Integrated Control

Managing your refugium's photoperiod is effortless with the built-in in-line controller. The system features three "one-touch" timing programs (6, 10, or 12 hours), allowing you to easily set a reverse daylight cycle to stabilize pH levels in your main display tank overnight.
