GHL Illumination


Optimal Lighting Conditions by GHL Luminaires

Optimal lighting plays a vital role in the success of aquariums and terrariums. It directly controls the photosynthetic activity of plants and coral symbionts, thus significantly contributing to the preservation of life and health of aquatic animals.

For this reason, we have dedicated countless hours to the research and study of natural lighting for use in aquariums. We seek to create the most realistic lighting scenarios found in nature so that aquatic animals can thrive under the natural lighting conditions that they are accustomed to.

The abrupt changes of light and intensity commonly found in different types of lighting are unrealistic in nature and pose unnecessary stress to animals; these characteristics do not exist in nature. Gradual changes in light spectrum and intensity are key. They support and encourage the biorhythm of animals and plants ideally.

All of our lamps are therefore, dimmable. They allow for gentle lighting transitions with gradual intensity and color changes to almost perfectly simulate true-to-life lighting conditions in the aquarium or terrarium.

Realize Natural Lighting Scenarios

Realistic illumination which follows the course of the day promotes typical behavior of your animals. By utilizing lighting effects such as sunset or moonlight, your fish tank becomes even more interesting and much like nature.

We offer several dimmable high-power LED lighting options and T8/T5 aluminum light bars for you to choose from.

The lamps manufactured in Germany by GHL offer:

  • Sophisticated technology and high quality material
  • Functional and modern design
  • Efficiency and durability

Together with the ProfiLux computer, automated lighting scenarios such as sunrise/sunset, clouds, rainy days, tropical dawnmoonlight simulation, seasonal lighting and thunderstorms are possible.
