The phenomenon of light

Digitally expressed, light is nothing more than electromagnetic radiation. Light is omnipresent, but not tangible. Life needs light - without light there would be no photosynthesis, no plant growth, no oxygen. But light is also emotion. We respond to harmonious colours and lighting moods. Therefore, the aspect of light is the most important cornerstone in aquaristics and should not be neglected.

Giesemann has been involved in the conception, development and production of optimal biological light for more than 30 years. We offer our customers handmade and state-of-the-art lighting systems for aquariums. So we also have maximum sustainability here, because even after many years it is still possible for us to repair luminaires.

All our luminaires benefit from our many years of know-how and knowledge. We always strive to develop the best product for you.


At home in all technologies

In 1991, the Giesemann company developed special lighting for aquariums with metal halide lamps and UV protection glass adapted to coral growth. In 2004, we already presented an aquarium luminaire with LED technology, making us one of the pioneers in the industry. Our portfolio of aquarium lighting ranges from contemporary aquarium LED lighting to high-end hybrid aquarium lighting and classic T5 aquarium lighting.

GIESEMANN offers a complete range of unique lighting systems including the associated light sources and control systems.
