Aquarium Lighting Basics: Their Purpose and Types

The aquarium is your own version of the sea world. You want to make your fish live in harmony with its environment, even though they are out of the wild. You use aquarium lighting not only to add beauty to their world but to also for better living conditions. There are different types of lights to choose from, and having these lights would depend on what you want them to do.

Aquarium lighting serves a variety of purposes, and one of these is for aesthetics. Lights can be used to make the tank look better and to highlight certain areas of your aquarium. Another reason is enhanced visibility. With illumination, different types of the fish can be seen better. They also look better when viewed from outside the tank. Aside from that, it would be easier to spot abnormalities or problems with the fish when sufficient lighting is present.

In most cases, aquarium lighting is installed because of need. In tanks that also contain coral and other invertebrates, lighting becomes essential to ensure the healthy living conditions of these organisms. This is because you need the right amount of light energy to initiate photosynthesis to keep corals alive. Usually, fish-only tanks do not need much lighting, while reef tanks need specific types of lighting. So if you have reefs and or coral or plan to have them in your tank, you should put more attention to the type of lighting to install.

For some tanks, the right lighting is essential. For tanks that have corals and fish, right lighting ensures that photosynthesis occurs. Corals and reefs need light of higher intensity. You need to have lights that provide exactly that.

Other considerations would be the size of the tank, the number and type of fish you have in the tank. For example, you may want to put in lights that mimic sunlight for tropical fish. Now that you have an idea of some of the reasons for installing aquarium lights, here are the types of aquarium lights available for you. These differ in the lights that they provide, the purpose that they serve, and the advances in lighting technology.

Incandescent lights cost less compared to fluorescent lights. When setting up a fish tank for the first, these are the kinds of lights you'd likely consider because of budget considerations. The disadvantage is that these lights heat up fast, break down easily, and consume more electricity.

Speaking about better light and energy efficiency, fluorescent lights fit the bill. These lights last longer, consume less electricity, and give out brighter lights. Aside from that, fluorescent lights also come in different types so you have more choices for your aquarium lights.

These lights are the lights of choice for people who own reefs and corals. Since these lights produce light at a specific wavelength, you can get a light that emits the right wavelength to induce photosynthesis. The only disadvantage is that these lights also heat up fairly quickly. You may need to install a cooling fan to keep the lights from overheating. Another thing to consider is that these lights can also heat up the water temperature; you might also need a chiller for your tank.

Power compacts are considered upgrades from your fluorescent lamps. Power compacts produce light of higher intensity, and also have the durability and energy efficiency of fluorescent lamps. These lights also come in different types and wavelengths, so if you need a specific wavelength, you can find one for your needs. These lights are usually U-shaped, while you can also find some that are coiled.
