The ATI 2x80W T5 High-Output Ballast is an essential replacement component designed to power two 80-watt T5 fluorescent bulbs in your saltwater aquarium lighting fixture. This ballast provides the stable and consistent electrical current necessary to ignite and operate high-output T5 lamps, ensuring your corals receive the optimal light intensity and spectrum for vibrant health and growth. It serves as a direct replacement for failed ballasts in compatible ATI fixtures, restoring your lighting system to its original performance.

This high-quality, non-dimmable ballast is engineered specifically for 2x80W T5 High-Output configurations.
