  • Regular price $26.00


Giesemann T-5 actinic-blue emits almost exclusively blue light of wavelengths from 400 - 510nm, with a maximum at 420nm. These wavelengths promote the growth of many coral species in the aquarium and thus provide optimal lighting conditions.

Since most aquarium inhabitants live in seawater depths where the light is very blue, it is needed to simulate this natural living conditions in the aquarium.

  • Developed to enhance the blue proportion in marine aquariums.
  • Reinforces the natural fluorescence of corals and brings them excellent to bear – especially in the twilight phase when being used alone.
The optimal use of the GIESEMANN actinic blue is the combined with either the GIESEMANN T-5 / super-actinic or super-purple or combined with our MEGACHROME HQI bulbs. GIESEMANN T-5 /actinic blue should never be missed for the lighting of coral reefs in any aquarium.


Many scientific research institutes and public aquariums rely on GIESEMANN lamps. This is an impressive proof of the outstanding quality of our products.
