Coralife T5 HO Actinic Blue
The Coralife T5 HO Actinic Blue is a high-output T5 fluorescent designed for reef and marine setups, delivering intense actinic wavelengths that make corals and fluorescent pigments pop while supporting photosynthetic organisms. Technically it offers higher lumen and photon density than standard T8 tubes, making it the market leader for color enhancement and coral fluorescence, though it’s less suited as a lone source for hearty freshwater plants compared with full-spectrum options or LEDs. Financially, it sits in the midrange — more expensive than basic T8 tubes but often necessary in mixed-light reef rigs where a dedicated actinic channel improves appearance and coral health.

Review Summary
"Buyers say the Coralife T5 HO actinic blue produces deep blue fluorescence that makes corals and fluorescent pigments pop and is great for nighttime viewing; some find it intense alone and usually pair it with daylight tubes and note eventual color shift over long use."
