“The sun does not shine for a few trees and flowers,
but for the wide world’s joy.”
– Henry Ward Beecher

Take a look at any of the best coral displays in reef aquaria around the world and you’ll notice a common thread: excellent lighting. With recent improvements in our capacity to manage water quality, flow, and, most importantly, light levels, increasingly diverse coral communities are being cultivated in captivity. While sophisticated, high-intensity lighting systems enhance the look of any reef tank, illumination serves more than just an aesthetic role. Exposure to appropriate wavelengths of light is critical for the welfare of live coral growing in aquarium settings.
