Some fish types are actually used to having 12 hours of full daylight, while others don’t need intense lighting at all, especially those species that come from shaded habitats.  Again, you need to be familiar with the living conditions your fish need to survive.  Remember that improper lighting results in stress, death, and lessened activity of your fish. When choosing any type of aquarium lighting, consider not just the aesthetics but also the functional qualities of the lighting device.  You cannot just pick any color that would make the aquarium look more attractive.  First check the lighting requirements of a particular fish type, such as the intensity, spectrum, and color temperature, particularly the Kelvin ratings. 

The cost of buying and installing the lighting device is also an important factor to consider when buying this kind of aquarium equipment.  While some are more energy-efficient than the others, the shorter lifespan of bulbs and lamps can also mean quick replacements, which add to the maintenance cost. Different types of aquarium lighting include incandescent and fluorescent lighting, compact and metal halide lighting, as well as lighting system combination.  Each has its own benefits and some downsides for you to consider.
