The Kessil AP9X LED Aquarium Light is 185 watts and covers a 4 foot by 2 foot mixed reef or a 3 foot X 2 foot SPS reef. All other aspects of the light have been improved on.

New Features:
    •    Light weight, low profile design. The AP9X is smaller and lighter. It's a more attractive light that is easier to mount.
    •    New LED colors. The LED clusters have a new Violet Channel (similar to a 20K radium halide) that helps coral color pop and grow.

    •    Built-in WiFi. The app interface has been completely redesigned to use the same software as the Kessil Wi-Fi Dongle for increased reliability and more detailed control.
    •    New Kessil light compatibility. The AP9X includes K-link and 0-10v ports for controlling all current Kessil light models. Use the AP9X as the hub to add A80s, A160s, A360s, A360Xs or the H series refugium lights and control them all from the same app. For the X-Series connect with the Kessil X-Series LED Light 90 Degree K-Link Cable and with the A80s, A160s, A360s and H series connect with the Kessil X-Series LED Light 90 Degree K-Link Cable.

    •    New Kessil AP9X Mounting Arm (SOLD SEPARATELY). The light weight design of the AP9X allows the use of a new single lower profile mounting arm for each light. The new mounting arms have the ability to swivel if you want to angle the light and reduce shadows and light bleed.
