the "water-LED" have times in nem Café for brunch seen. Since my friend is an absolute light fanatics, of course he was immediately hooked ... The LED is highly recommended, they do even now after 2 years still almost daily. Only a very faint humming sound can be heard, since you have run anyway but mostly music or TV in the background, it does not bother me. My girlfriend was also thrilled, gave it too her boyfriend and they are further very enthusiastic. Makes a very nice light and a nice atmosphere. Are repeatedly addressed by visiting it
