The T5 Giesemann Powerchrome Actinic Blue 80W (1450 mm) tube offers an intense blue spectrum (400–510 nm) ideal for stimulating fluorescence and coral growth. Designed for reef aquariums, it faithfully reproduces the natural light of deep ocean areas and enhances the colors of your reef.
The Powerchrome T5 Actinic Blue 80WGiesemann is a high-performance light specifically designed for reef aquariums. It reproduces the light spectrum of the deep sea, dominated by blue wavelengths, favoring the photosynthesis of zooxanthellae and the growth of corals.
The Actinic Blue lamp emits almost exclusively in the range of 400 to 510 nm with a peak at 420 nm, corresponding to the energy needs of marine organisms. This spectrum enhances the corals' natural fluorescence , while creating a striking visual effect, especially during the twilight phase.

This Giesemann Powerchrome Actinic Blue fluorescent tube enhances the blue wavelengths of light (400 to 510 nm, peak at 420 nm), replicating the natural conditions encountered at certain depths at sea. It thus promotes the growth and coloring of corals in reef aquariums .
Corals and symbiotic organisms (zooxanthellae) use blue light for photosynthesis. This wavelength supports their metabolism, stimulates natural fluorescence and improves the visual rendering of the reef, especially in the twilight phase.
For a full and balanced spectrum, it is recommended to combine the Powerchrome Actinic Blue with other Giesemann tubes such as the Aquablue Azur or the Aquablue Coral. This combination faithfully reproduces the light of the natural reef.
Yes, its spectrum accentuates the natural fluorescence of corals, which gives a spectacular visual effect, especially visible in the evening or in twilight mode.
Thanks to the use of high-quality fluorescent powders, Powerchrome Actinic Blue offers excellent colour stability and a long service life, ensuring consistent light performance over the long term.
This tube is available in different wattages: 8W, 24W, 39W, 54W and 80W (length 1450 mm for this model). It can thus be adapted to all types of T5 ramps and marine aquariums.
