A compact aquarium light is a type of fluorescent fixture that can be used for both freshwater and saltwater aquarium systems. Compact aquarium lighting is widely used among hobbyists because it is a low cost, low energy solution. Power compacts may be used by themselves or in conjunction with metal halide lighting. Compact light bulbs should be replaced every 9-12 months. Compact aquarium lights are great for fish-only systems and reef tanks with corals that require low-to-moderate lighting.
