High-Performance LED Lighting for Reef Aquariums

Greater Light Output with Refined Color Control

Built on the AP9X platform, the Kessil AP9XE delivers approximately 10% more light output while maintaining a maximum power consumption of 185W. Combining Kessil's Dense Matrix LED technology with expanded color control and built-in WiFi, the AP9XE provides powerful, even illumination for a wide range of reef aquarium setups.

Technical Features & Build

  • Enhanced Light Output: Delivers approximately 10% more light output than the AP9X without increasing maximum power consumption.
  • Dense Matrix LED Technology: Uses two LED arrays to produce a powerful point source with smooth color blending and Kessil's signature natural shimmer.
  • Expanded Color Control: Combines the Tuna Blue spectrum with individually adjustable red, green, and purple channels, including violet and indigo wavelengths.
  • Broad, Even Coverage: Illuminates mixed reef aquariums up to 48" x 24" and SPS-dominant systems up to 36" x 24".
  • Kessil Logic: Maintains a balanced spectrum as users adjust color settings, helping preserve essential spectral output.
  • Built-In WiFi: Enables wireless lighting control and remote management without requiring a separate WiFi dongle.
  • Flexible Connectivity: Supports K-Link and 0–10V connections, with compatibility for Spectral Controller X.

The AP9XE brings together increased output, broad coverage, and flexible lighting control in a slim, low-profile fixture, giving reef keepers greater control over their aquarium lighting.
