Kessil support FAQ

Common questions about manuals, registration, and support for this brand.

  • Why is my Kessil light flickering?

    Flickering may indicate an issue with the fan or overheating. Ensure the fan is operating properly and that the unit is not running in an environment above 100°F (40°C).

  • How do I control multiple Kessil lights together?

    Multiple Kessil fixtures (like the A360X) can be linked using K-Link cables. Once connected, controls on the primary light will adjust the others, or they can be managed via the Spectral Controller X or WiFi Dongle.

  • Can Kessil lights be used outdoors?

    No, Kessil aquarium and horticulture lights are generally intended for indoor use only. Do not expose the units to extreme humidity or submerge them in water.

  • My Kessil light does not turn on. What should I check?

    Verify that the power adapter is securely connected and meets the specified voltage requirements. Ensure the AC outlet is functioning and that the unit has not shut down due to overheating.
