JBJ MACRO-GLO Refugium Light – Adjustable 15W & 25W LED for Optimal Macroalgae Growth in Sumps and Refugiums

Compact Brilliance for Modern Aquascaping

The MACRO-GLO Adjustable Refugium Light is designed to maximize nutrient export and macroalgae growth in compact sump and refugium spaces. Featuring high-efficiency red/blue LED wavelengths and two power options (15W and 25W), it delivers intense PAR where you need it most — promoting healthy Chaetomorpha, Gracilaria, and other macroalgae growth to stabilize your reef system.

Optimized Spectrum for Algae
High PAR output in the 660nm red and 460nm blue spectrum — ideal for photosynthetic macroalgae.

Two Wattage Options
Choose between 15W for nano or compact refugiums, and 25W for higher-demand systems with more space and macroalgae biomass.

Adjustable Gooseneck Mount
Flexible arm positions the light exactly where needed, whether over a sump chamber or HOB refugium.

Low Heat, High Efficiency
Runs cool with low energy use and reliable LEDs for long-term, continuous use.

Quick Installation
Mounts easily to the sump rim or tank edge — no tools required.

Is this good for Chaetomorpha?
Yes, the red and blue spectrum is ideal for fast, dense Chaeto growth.

How is it mounted?
The light uses a clamp and gooseneck that secures to the edge of a sump or refugium chamber.

Can it run 24/7?
Yes, it's designed for long-term use and can safely operate continuously.

Does it produce heat?
Very minimal — the passive aluminum design helps dissipate heat without fans.
