The ATI Coral Plus T5 HO Lamp is a high-output fluorescent bulb designed to provide a complete and balanced spectrum for saltwater reef aquariums. It uniquely combines the properties of three different ATI bulbs into a single lamp, blending the spectra of the Blue Plus, Aquablue Special, and Purple Plus. This combination produces a crisp, cool white light with an approximate color temperature of over 15000K, enhancing coral coloration and promoting healthy growth while providing a brilliant, natural-looking illumination for your entire reef display.

Engineered in Germany, the Coral Plus bulb's spectral output is composed of approximately 50% Blue Plus, 40% Aquablue Special, and 10% Purple Plus. This versatile design makes it an excellent choice for use as a standalone bulb for a bright, full-spectrum look. It is also highly effective when integrated into multi-bulb fixtures, often paired with additional Blue Plus and Purple Plus bulbs to create customized lighting solutions. Popular configurations for 6-bulb fixtures, for example, often utilize three Blue Plus, two Coral Plus, and one Purple Plus bulb for a vibrant, actinic-rich spectrum.

This lamp is ideal for reef hobbyists seeking the proven performance and full-tank coverage of T5 lighting. It is perfect for aquarists who want to achieve a bright, white aesthetic that makes coral colors pop without washing them out. Whether you are setting up a new T5 system or looking to refine your existing bulb combination, the Coral Plus offers a powerful and efficient way to support photosynthetic corals, from soft corals and LPS to more demanding SPS, by delivering a broad, usable light spectrum.
