The Fluval T5 HO Sea Actinic Bulbs are essential for aquarists seeking optimal conditions for photosynthetic corals and invertebrates. These bulbs replicate the important actinic blue wavelength required for coral health and vivid coloration. Designed to enhance the visual appeal of your marine aquarium, they accentuate blue and violet tones, making your aquatic life flourish.

Engineered to produce a strong and consistent blue spectrum, these bulbs are particularly effective in promoting coral growth. The enhanced lighting conditions also serve to highlight the blue coloration in fish and other invertebrates. With a superior light output maintained over the bulb's life, these bulbs outperform conventional fluorescents in both lifespan and efficiency.

• Strong actinic blue spectral peaks for coral health
• Enhances aesthetic appeal with visible blue spectrum
• Greater light output per bulb surface area
• Long lifespan versus comparable fluorescents
• Compatible with T5 HO-specific electronic ballast

Optimising light conditions in your aquarium, the Fluval T5 HO Sea Actinic Bulbs support both the health and appearance of your marine life. Their extended lifespan and high efficiency make them an excellent choice for maintaining a vibrant underwater environment.
