Manufacturer Info 

GHL was founded more than 10 years ago. First we mainly focused on development orders (in the sections hardware, software and special machinery), later the technics for aquatics – aquarium controllers and dimmable illumination – became more and more important. The small but innovative company turned quickly into a worldwide operating enterprise. The constant high quality of the products and permanent new and further developments made GHL one of the leading companies who produce technology for aquariums, terrariums and ponds. Especially the permanent market observation and the intensive dialogue with the customers made this success significantly possible which was also honored in 2005 with an innovation price of the federal state Rhineland-Palatinat.
