Kessil AP9X Kessil AP9X! Redesigned optics provide an even light distribution that blankets your aquarium with up to 48” of coverage.
Kessil X-Series lights now interface with the Neptune APEX Fusion app through either the WiFi Dongle (A360X and A500X) or directly through an AP9X.
This uniform coverage minimizes hotspots and creates an effect similar to that of a metal halide / T5 combo.
In addition to Kessil’s signature Tuna Blue spectrum, the AP9X features a full range of individually adjustable color channels (red, green, purple) that can be accessed via the Kessil app. Kessil Logic™ ensures that cosmetic color settings do not interfere with the core spectrum, allowing users to dial in a preferred color without disturbing coral health. The AP9X also includes 395nm LED chips, which emit True UVA light for maximum coral coloration.
PAR measures all visible light (400-700nm) unweightedly, but coral health primarily relies on the 425nm (violet) and 455nm (royal blue) wavelengths. Kessil LEDs focus on these essential wavelengths, prioritizing coral growth and propagation over inflated.
The signature Kessil shimmer effect gives your tank a beautiful, natural, sunlit look comparable to the shimmer of a Metal Halide fixture - replicating your own piece of the ocean.
