Powerful actinic blue T-5 fluorescent bulbs ideal for marine aquariums. Fluval Marine-Glo T-5 HO bulbs emit light with strong peaks in the actinic blue spectrum, making them perfect for saltwater aquariums housing photosynthetic corals, invertebrates, and other marine life. Visible blue spectrum light also accentuates blue coloration in marine fish and corals.
Use T-5 tubes with compatible T-5 light fixtures with high output electronic ballasts to help increase efficiency and tube life. For optimal performance, replace bulb every 8 to 12 months.
