The Kessil H160 Tuna Flora LED Refugium Light is a specialized horticultural lighting solution meticulously engineered for saltwater reef aquariums. Leveraging the same advanced platform as the Kessil A160, this powerful LED is precisely tuned to stimulate maximum photosynthesis in marine plants, primarily macroalgae and turf algae scrubbers, within a refugium setting. By focusing its energy on the critical blue and red spectrums, it efficiently drives robust plant growth, facilitating superior nutrient export from the main display tank. This compact yet potent 40-watt fixture delivers effective light output comparable to a 175-watt metal halide, covering an area up to 24 inches. It exclusively utilizes blue and red LEDs, ensuring optimal chlorophyll stimulation without any white light, resulting in a distinctive pinkish glow. Key features include a variable color temperature knob for fine-tuning the spectrum, a fanless shell-shaped design for completely silent operation and effective heat dissipation, and the ability to control intensity and spectrum via on-fixture dials or the Kessil Spectral Controller. Multiple units can also be daisy-chained for synchronized control. Ideal for serious reef aquarists dedicated to natural nutrient reduction, the Kessil H160 Tuna Flora LED is the perfect choice for supercharging refugiums and algae scrubbers. Its targeted spectrum and high efficiency promote unparalleled macroalgae growth, effectively exporting nitrates and phosphates to maintain pristine water quality and a healthy reef environment. For those seeking a silent, powerful, and precisely tuned lighting solution to enhance their biological filtration, this light offers exceptional performance and reliability.
