New E-Series LEDs are 15% brighter with the same wattage consumption, resulting in even better penetration and more intense shimmer.
Beautiful, unrivaled shimmer gives the look of natural sunlight in your aquatic garden.
Kessil is the only company to manufacture all LED arrays in-house with custom spectral blends specifically tailored to meet aquarist needs.
Leveraging years of Kessil's own grow light research, our LEDs now emit a "Double Peak" spectrum, which improves plant color and growth by enhancing photosynthetic absorption.
Patented Dense Matrix LED™ technology concentrates multiple LED chips into an array, creating a powerful light source with better and deeper penetration, without sacrificing coverage.
Different wavelengths within a single LED array are seamlessly blended before leaving the light, emitting a uniform color with widespread coverage.
High performance and low maintenance. Simple and compact units feature quiet operation, innovative heat management and efficient, long-lasting LED construction.
Tune the spectrum and intensity for a personalized look. Kessil Logic™ maintains consistent output across the spectrum. 6,000-9,000K.
Compatible with 0~10V external controllers. Daisy-chain multiple lights for seamless control from a single source.
3.8" x 4"
Up to 24" surface diameter
100-240V AC (input)
19V DC (output)
When introducing new corals to a tank or new lights to an existing system, it is highly recommended to go through acclimation in order to reduce stress. For tunable Kessil lights, it is best to start at 50% intensity and increase the intensity 5-10% per week until the optimal level. Monitor how the corals are reacting while acclimating and either increase or decrease the level of light as necessary. Please note that not all tanks will need the lights to be on 100%. The optimal lighting is different for each tank.
Additionally, the Kessil Spectral Controller can be used to automatically control acclimation. The controller is compatible with the A160 and A360 lines.
Once your lights are installed, they will need to be routinely cleaned and maintained in order to ensure optimal performance and a long life span. Every month, clean the lights out thoroughly with compressed air by blowing the lights out through the side vents. Use rubbing alcohol to gently wipe the glass lens.
