The heart of the ADA Lighting System is the unique, true 8000 Kelvin lamp. Standard wattage fluorescents, Power Compact, and the flagship HQI halogen all feature the most ideal color temperature of 8000 K developed after extensive research of the nature of the underwater light field in several of the world's most prominent regions for aquatic plants. ADA Lighting System fixtures are extremely high-quality, and feature external ballasts on all suspended fixtures, which ensures lower fixture weight and more flexible suspension options. The sleek architectural design is both attractive and highly effective in the dissipation of heat. The ADA basic concept is a high-technology lighting system that meets the demands of aquatic plants.
