Last updated 2026-11-03

This specialized LED fixture is designed for use with refugiums and aquatic plant growth. It utilizes a specific blend of red and blue light wavelengths that are known to promote efficient photosynthesis in macroalgae and other water-based plants. The compact, circular design allows for concentrated light delivery in tight spaces under an aquarium.

The light features adjustable spectrum controls, allowing the user to fine-tune the output based on the specific needs of the aquatic life. This level of control helps in managing the growth rate and health of the refugium, which in turn helps maintain the water quality of the main tank. The build quality is robust, intended for humid environments.

This unit is a professional-grade option for reef keepers and aquarists who need reliable plant growth in a sump or refugium. The focused beam ensures that light energy is directed exactly where it is needed, minimizing waste. It is a dedicated tool for those focusing on the biological filtration aspects of a marine or freshwater system.
