An aquarium will most likely be provided with a lighting fixture for the dual purposes of providing a nice-looking source of illumination for aquarium viewing, and stimulating the growth of marine life. The primary purpose of most aquarium lights is to offer an attractive illumination of the aquarium tank and its contents, for viewing. Aside from that, aquarium lights also support the growth of marine life, including marine plants, coral, and potentially algae. These waterproof lights attach to the inside edge of the aquarium frame to present primary lighting to an aquarium, or to add supplemental illumination to an aquarium. Conventional aquarium lights use either fluorescent bulbs, halogen incandescent bulbs, or metal halide (MH) incandescent bulbs. Fluorescent bulbs, as well as incandescent bulbs, including halogen and metal halide light sources, provide a rather broad spectrum of light, and can provide good or otherwise acceptable color rendering. However, their spectral content is fixed. As a result, varying the spectral content over time isn't feasible, unless multiple bulb types are employed in the light. Aquarium lights using light emitting diodes (LED) offer quite a few potential advantages over fluorescent or incandescent bulbs. This LED fixture provides a high quality, energy efficient light fixture that replaces the typical fluorescent light. By combining multiple LEDs of specific wavelengths, it is possible to personalize the overall spectral content of the light source, for either a particular visual presence, or for encouraging the growth of marine life. Replicating the dynamic natural qualities of sun and moon lighting, LED aquarium lights combine the life-sustaining wavelengths of light together with the efficiency of LED technology into a low profile, stylish lighting system. The powerful LED chips add the natural shimmering effect and rippling glow seen on natural coral reefs while producing almost no heat and consuming a small amount of electricity. These lights add vibrancy and movement to just about any aquarium by enhancing colors in fish and corals and can be used to provide impressive lighting effects in the day or night.
