The GIESEMANN T-5 / super-actinic emits a very strong, pure actinic spectrum, which generates a light white/violet effect in your aquarium that maximizes the fluorescence from your colorful corals. Ideal for supplementation of existing metal halide lighting. Some corals reach its beauty and expression only by special fluorescent colors. Like many mussel species these animals will be found in the sea at water depths where specific UV-components are available. Therefore we have developed a fluorescent lamp that will bring these colors into the home aquarium. The GIESEMANN T-5 / super-actinic is a high-performance T5 tube, emitting a very strong, pure actinic spectrum, which generates a light white/violet effect in your aquarium. GIESEMANN T-5 / super-actinic increase the fluorescence, enhance a maximum fluorescence from your colourful corals and lendfs itself to an ideal addition to your metal halide lighting (HQI). Many scientific research institutes and public aquariums rely on GIESEMANN lamps. This is an impressive proof of the outstanding quality of our products. GIESEMANN T-5 / super-actinic are available at all power levels 24, 39, 54 and 80 watts.
