Choosing aquarium lighting
Compare the light's intended application, mounting position and the distance to the animal or tank. Screens, covers and fixture design can affect the installed setup.
Read spectrum, exposure-distance and controller specifications for the exact model, with requirements based on the species or aquarium being kept.
Continue with Freshwater & Planted Tank Lights, Reef Aquarium Lights, and Light Mounts & Controllers to compare the equipment for a more specific task.
