Fluval Sea T5 HO Actinic Aquarium Bulb replicates the essential actinic blue wavelength that corals and other photosynthetic invertebrates require. Strong blue light is also effective at enhancing fish colors, accentuating blue and violet tones.

Key Features:

• Provides strong and essential actinic blue spectral peaks
• For intense coral color and growth
• Enhances fish colors
• Produces more light per bulb surface area versus conventional fluorescents
• Longer life versus other comparable high output fluorescents
• Maintains superior light output over the entire bulb life versus other comparable fluorescents
• Strongly recommended for photosynthetic coral, invertebrates and other marine life
• Visible dominant blue spectrum highlights blue coloration in fish, corals and other invertebrates
• For use with a T5 HO-specific electronic ballast only
• Size: 55 cm (22″”)
