Giesemann Aquaristic 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. The Giesemann Actinic Blue has therefore been developed to enhance the blue proportion in marine aquariums. Giesemann Actinic Blue emits almost exclusively blue light of wavelengths from 400 - 510 nm, with a maximum at 420 nm. These wavelengths enhance the growth of many coral species in the aquarium, thus ensuring optimum lighting conditions.

Giesemann Actinic Blue 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 Giesemann Actinic Blue is the combined with either the Giesemann super actinic or super purple or combined with our MEGACHROME HQI bulbs. Giesemann Actinic Blue should never been missed for the lighting of coral reefs in any aquarium.

Length (including pins): 22 1/8”

REVIEW
I put in 2 super actinic and 4 aquablue coral bulbs. They are all nice, but quite purple tinged. The super actinics put out a lot of fluorescence, very bright, but they are like black lights as they have more bright blue and purple.

REVIEW
These bulbs are so intensely blue that they actually have a purple tint...makes corals and fish really pop. And, BTW, the packaging provided by MarineDepot was complicated, but did the job very well...these are delicate bulbs, but they arrived intact.

REVIEW
The lights are bright and the corals seem to like them fine. They appear a little more purple than I expected. That's not a bad thing, I can now take out my purple bulb and put in a more daylight color. Would buy again.

Fantastic Bulb!

REVIEW
This is my new favorite balanced white bulb. It is a really clean white with a touch of blue, and there is a definite increase in fluorescence of the corals when it is on. This bulb is different than the old DD-Giesemann Lagoon blue.
