    We recommend mounting Kessil lights 8-12 inches above the water surface for the ideal coverage.

    All Kessil aquarium lights are compatible with the A Series Gooseneck. The base of the gooseneck features a clamp that can be mounted onto glass or acrylic tanks and is also compatible with euro brace styles.

    The light attaches onto the gooseneck via a bracket. There are three variations of the bracket one for the A3XX line, and a third for the A1XX line.

    The gooseneck package includes the A3XX bracket. The A1XX brackets are included with the light.

    The 90 Degree Gooseneck Adaptor can be used to extend the reach of the gooseneck.

    It is also possible to mount the lights inside a canopy. Be sure to allow enough room for ventilation or the fixtures may overheat and become damaged.
