Ushio Aqualite metal halide lamps utilize proprietary rare-earth mixtures to provide the most consistent lamp color over the entire lifetime of that lamp. Ushio's arc tube forming process and coatings ensure that light degradation levels are kept to a minimum. For the best health of your aquarium and reef system, it is recommended that you schedule regular lamp changes depending upon your timing cycles and rated lamp life, generally every 10 to 12 months. Ushio bulbs have set the standard for high quality lighting that all other bulbs must follow.
