The Giesemann Actinic Blue T5 Lamp almost exclusively emits blue light with wavelengths ranging from 400 – 510 nm, with a maximum at 420 nm. These wavelengths enhance the growth of many coral species by simulating their natural living conditions. They also accentuate the beautiful fluorescence of your corals and other aquarium inhabitants, especially when used alone as a lunar light source. Made in Germany.
