Kessil LED Fixtures have been one of the top selling brands in North America for several years. Sleek design, color uniformity, shimmer and relative affordability have made this brand into what it is today.

Beautiful, unrivaled shimmer replicates the look of natural sunlight on the ocean floor.


A proprietary blend of UV light enhances coral growth and color.


Patented Dense Matrix LED technology concentrates multiple LED chips into a single array, creating a powerful and penetrating light source with a wide coverage area. The average penetration of an A160WE is 24" to 30" for most reefs. 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.
