GRO Refgium Light with Flat Mount Bracket Mount

Purpose:  The GRO is a specialized, 20W LED light designed to grow many types of common macroalgaes (i.e. Chaetomorpha) using a specialized light spectrum which maximizes photosynthesis. It plugs directly into any available DC24 port in your Apex ecosystem, or alternatively, it can also be run completely standalone.

For complete information please see the GRO product page.

Key Features:

  • Compact LED grow light with 84 LEDs in four colors, two key spectrum ranges for optimal macroalgae growth
  • Large, flat area of illumination promotes better growth as it creates a much more even spread than single, spotlight-style lights.
  • Distributed LED design means no light hotspots that can burn the macroalgae
  • Less light spillage - IP64 water resistance means it can be placed very close to water -- reducing the growth of nuisance algae elsewhere
  • Two focused wavelength bands (455-460nm and 620-670nm) for maximum algae photosynthesis
  • Utilizes an 18" long, flexible gooseneck attached to the flat mount bracket that clamps to a flat edge such as the edge of your sump or support on your stand.


  • An available, powered, DC24 port in your Apex Ecosystem
  • Optional 24V power supply to run standalone
