Shimmer Beautiful, unrivaled shimmer replicates the look of natural sunlight on the ocean floor. Penetration Patented Dense Matrix LED technology concentrates multiple LED chips into a single array, creating a powerful and penetrating light source with wide coverage. The average penetration of A160WE is 24" to 30" from the water surface for most plants. Penetration can be further enhanced by positioning multiple units in close proximity to each other. Color Mixing Different wavelengths are seamlessly blended within a single LED array, emitting uniform color across the coverage range. Design Tunable - Kessil Logic™ maintains consistent output across the spectrum. 6,000K to 9,000K. Heat Management - Our innovative heat management system enhances efficiency and longevity. Dense Matrix LED - Our densely-packed LED array emits more high-quality light than competing fixtures. Kessil Technologies Control - Compatible with 0 ~10V external controllers, Kessil Spectral Controller & Kessil Spectral Controller X. Daisy-chain multiple lights for seamless control from a single source. Manual Mode - Instantly tune spectrum and intensity for on demand light customization.
