The Professional Lighting Control with many Smart Extra Functions.

Achieving natural lighting conditions in your aquarium has never been easier.

The compact aquarium controller Profilux Light offers many familiar features found in the proven high-end ProfiLux 3 and 4 series, all at an attractive price.

ProfiLux Light can control dimmable and non dimmable lighting, variable speed flow pumps, and much more. It can also be operated via USB with the PC-software GHL Control Center, which is available free of charge.

The new ProfiLux Light WiFi variant also has integrated WiFi and can therefore also be operated via GHL Connect (app and web interface) and the myGHL cloud service. With the optional available ProfiLux Mini/Light-Adapter (SKU PL-2024) ProfiLux Light WiFi can also be connected to level sensors (for auto top off and automatic water change) and the GHL automatic feeder.

The ProfiLux Light automated lighting control function provides you with unique lighting features. When combined with our LED illumination solutionsfascinating light scenarios can easily be made.

ProfiLux Light gives you the option to adjust your illumination settings and fully automate your lighting fixture for day to day functions such as Sunrise/sunset, Cloud cover, Rainy days, Tropical dawn, Calendar-based moonlight simulation, Seasonal lighting, or Thunderstorm simulation.

Operation of the ProfiLux Light is simple and intuitive. All settings are user friendly and guided by interactive dialog. No programming skills required here!

The ProfiLux Light is easily accessible using the keypad and graphical display on the device.

We offer regular firmware updates to ensure that your ProfiLux remains future proof and is always up to date.
