For a 30-50 gallon fish tank, with the length of around 36 inches, a 36-inch LED aquarium light fixture is perfect for the widespread light coverage of the entire tank. This will ensure the tank is fully illuminated, and the optimum light is catered for your aquatic life.
To make your sound decision when choosing an LED aquarium light, you must ask yourself which type of aquatic life you plan to have in your tank. A primarily fish oriented tank will need an LED light that can provide natural lighting colors to mimic those in their natural habitats. Plants and corals however, will need
LED lights that provide both right colors and enough intensity to help promote photosynthesis and growth.
