GRO Refgium Light with Flat Mount Bracket Mount

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

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
