"The three colour channels harmonize very well and offer a balanced colour mixture that impressively sets the scene for both plants and fish [...] I would like to take this opportunity to thank Giesemann for this top-of-the-range aquarium lighting product."
"With the new VIVA tropic, Giesemann has now launched "my favorite lamp" [...] The workmanship of the VIVA is typically Giesemann's exceptionally high quality."
Dr. Bastian G. (Nuremberg)
"In addition to the actual product, the pre-sales and after-sales service is just as important to me. The telephone contact before and after the purchase was always very pleasant and extremely knowledgeable."
