Kessil Spectral Controller X Aquarium Light Controller with Touchscreen Scheduling

The Kessil Spectral Controller X is a touchscreen aquarium light controller for adjusting color and intensity or creating light schedules, with K-Link networking for compatible A360X fixtures.

• Touch control and a vivid color display — adjust lighting through an on-screen interface.
• Manual and Program modes — customize light settings on demand or create aquarium-specific schedules.
• Two-way K-Link communication — view connected light count and status.
• K-Link and 0-10V ports — connect compatible A360X and legacy Kessil fixtures.
• Magnetic back plate, mounting hardware, and a 10 ft (3.05 m) K-Link Cable included — support setup with the supplied accessories.

Aquarium lighting can require different settings at different times or for different tank setups. The Spectral Controller X gives you a way to adjust compatible Kessil lights directly or set up a customized schedule, while its compact, modern design is made to fit into an aquarium setup.

Which Kessil lights can the Spectral Controller X connect to?

The K-Link port connects to A360X Tuna Sun and A360X Tuna Blue fixtures, while the separate 0-10V output supports the A360WE, A360NE, A80, and A160. With K-Link, compatible lights can be networked and assigned to groups running their own programs. A360X networks support up to 32 fixtures per chain; Kessil also specifies no overall light-count limit when lights are linked with K-Link cables.

• One K-Link port and one 0-10V output port.
• Two-way communication can detect network light count and fixture status.
• One additional K-Link Cable is needed for each additional light; one cable is supplied.

How can I adjust lighting and create a schedule?

Manual Mode lets you tune color and intensity for on-demand adjustments, while Program Mode offers two ways to set a customized light schedule. You can create up to 12 programs to suit individual tank needs. Touch controls and a color display provide the interface for making those settings.

• Use Manual Mode for immediate color and intensity changes.
• Choose Program Mode to create scheduled lighting.
• Store a maximum of 12 programs.

What comes with the controller, and what cable do older lights need?

The package includes one Spectral Controller, one Magnetic Back Plate, one Micro USB Cable for firmware updates, one 10 ft (3.05 m) K-Link Cable, two screws, and two nylon anchors. The 0-10V connection for the A360WE, A360NE, A80, or A160 requires the older Unit Link Cable, which is not included.

• Included: one controller, one magnetic back plate, and one firmware-update cable.
• Included: one K-Link Cable, two screws, and two nylon anchors.
• For additional lights, use extra K-Link cables; the 0-10V port needs a Unit Link Cable.

The Spectral Controller X suits aquarium keepers who use compatible Kessil fixtures and want touch-based adjustments, custom schedules, or networked light control. Its K-Link and 0-10V connections support the specified A360X and legacy fixtures, with both manual tuning and programmable lighting available from one controller.
