Description
ATI Aquablue Special T5 HO Bulb
The ATI Aquablue Special is a high-output T5 bulb designed to serve as the foundation for reef aquarium lighting. By combining the properties of a full-spectrum bulb with an elevated blue peak, it delivers a crisp, cool-white light that mimics the natural environment of shallow-water reefs.
Spectrum & Color Performance
Color Temperature: Approximately 15,000K.
Visual Output: A bright, high-clarity white with a distinct blue undertone. It provides a clean aesthetic that eliminates the “yellow” look often associated with standard daylight bulbs.
Functional Design: This bulb is engineered to balance high PAR (Photosynthetically Active Radiation) output for coral growth with excellent color rendition for fish and invertebrates.
Key Features
German Engineering: Manufactured using the latest advances in phosphors to ensure higher output, better color stability, and a longer lifespan.
Versatility: While it can be used as a standalone bulb for a bright look, it is most commonly paired with the ATI Blue Plus or Purple Plus to customize the exact fluorescence and color pop of your reef.
Proven Results: Trusted for over 20 years by coral farmers and hobbyists for its ability to drive growth in both SPS and LPS corals.

Recommended Use
For a well-balanced “standard” reef look, many users find success with a 1:1 ratio of Aquablue Special and Blue Plus bulbs. If you prefer a more “blue” or “actinic” look, the Aquablue Special can be used as the primary growth driver alongside multiple Blue Plus or Coral Plus bulbs.
Best For: Reef tanks, saltwater aquariums, and high-tech planted tanks where a crisp 15,000K look is desired.
Warranty: Includes a 30-day fail-to-fire warranty.
