Refugium Grow Light Tuned for Macroalgae and Plant Photosynthesis
The Kessil H160 is a 40W Dense Matrix LED refugium grow light dialed in for chlorophyll-driven photosynthesis. The fixture delivers four blended bands - blue, GROW, BLOOM, and red - across 380-780 nm with UV-A and infrared. Effective output rivals a 175W metal halide while pulling 40W. Recommended spread is 18 x 18 inches.
Tunable Blue-to-Red Spectrum for Macroalgae and Refugium Builds
Growers typically mount the fixture 6 to 14 inches above the refugium. Tune the spectrum knob toward red for chaetomorpha and toward blue for caulerpa. Place the H160 above the macroalgae tray to drive nutrient export across the sump cycle. Pair with any standard 0-10V controller for scheduled photoperiod control.
