Aquatic Life T5 HO Lamps are filled with a gas containing low pressure mercury vapor, argon, xenon, neon, or krypton. The pressure inside the lamp is around 0.31% of atmospheric pressure. The inner surface of the lamp is coated with a phosphor coating made of varying blends of metallic and rare-earth salts. The cathodes at each end of the lamp emit electrons when energy from the ballast is delivered to the lamp. This energy mixed with the phosphor transforms the ultraviolet radiation into visible light. The color of the light depends on the composition of phosphor. Each batch of Aquatic Life lamps is carefully tested to ensure consistent light output and quality. Visible Hue: Actinic Blue. Kelvin: 420/460nm. Application: Marine Fish & Corals. Ideal for: Acroporas (SPS), Anemones, Clams, Hard Corals (LPS), Leathers, Mushrooms, Polyps, Soft Corals, Xenia. Benefits: Mix of Actinic and Royal Phosphors produces a light spectrum that benefits most corals and enhances fish colors.Item Numbers: (410218) T5HO 18" 18W Actinic Blue (410039) T5HO 24" 24W Actinic Blue, (410041) T5HO 36" 39W Actinic Blue, (410043) T5HO 48" 54W Actinic Blue.
