Powerchrome Actinic Blue 54W

The Giesemann Powerchrome Actinic Blue 54W is a premium 1150 mm HO T5 fluorescent tube engineered to provide a pure actinic spectrum ranging from 400 to 510 nm, with a sharp peak at 420 nm. Manufactured in Germany using advanced tri- and penta-phosphor blends, it is specifically designed to maximize coral fluorescence and drive zooxanthellae photosynthesis. Excellent for creating atmospheric dusk-to-dawn transitions in 120 cm T5 and hybrid fixtures, this dimmable bulb maintains color stability for up to 10,000 hours while preventing early end-blackening.

Key Features

• Powerchrome Spectrum: Proprietary formula using high-purity tri- and penta-phosphor blending for outstanding color output and spectral stability for up to 10,000 hours.
• Targeted PAR Output: Actinic blue spectrum peaking at 420 nm, specifically engineered to support zooxanthellae growth and stimulate deep coral fluorescence.
• German Manufacturing: Premium-grade cathode and filament construction, made in Germany, preventing early end-blackening in this 54W bulb.
