The lighting engineers over at Neuco Germany developed the Aquastar lamp to simulate a more near-nature light spectrum resulting in brilliant color reproduction, enhance coral growth and long-term color stability.  The Aquastar 14500K contains very high percentage of a refined blue spectrum to bring out the fluorescent pigments in corals and to better simulate the natural light conditions over a coral reef. This new soon to be popular German lamp provides substantial improvements over other bulbs found in the 12-14k class.  Will be available in 250w SE and DE Bases as well as a 400w SE (mogul) base. They will fire on any electronic ballast.
