The Neptune Systems GRO LED Refugium Light is engineered to deliver optimal macroalgae growth, supporting natural filtration and nutrient export in your reef aquarium. With 84 LEDs tuned to the ideal photosynthetic spectrum and a wide rectangular design, the GRO provides powerful yet efficient illumination exactly where it’s needed—without excess light spill. Compact, water-resistant, and easy to set up, this 20W refugium light makes growing macroalgae simple, effective, and energy efficient.
Specialized Spectrum – Optimized wavelengths (455–460nm & 620–670nm) maximize macroalgae photosynthesis.
Compact & Efficient – 20W output using 84 evenly distributed LEDs ensures uniform coverage.
Smart Shape Design – Wide rectangular panel matches refugium layout, preventing wasted light.
IP64 Water-Resistant – Built tough for sump and aquarium environments.
Plug & Play Setup – Easily connects to DC24 ports on an Energy Bar 832 or 1LINK module.
Standalone Option – Operates independently with an optional 24V DC power supply.
Natural Filtration Support – Encourages nutrient reduction, pH stability, and micro-fauna growth.
Promotes thick, healthy, and abundant macroalgae growth for nutrient export.
Provides a natural solution for maintaining reef stability and balance.
Helps stabilize aquarium pH with reverse daylight photosynthesis cycles.
Creates a safe habitat for beneficial micro-fauna, enhancing biodiversity in your tank.
