It’s super bright 50W design, with a 90-degree lens and 56pcs chips, ensures uniform illumination for marine aquariums up to 24″ deep, keeping PAR/Lumen Output and coverage balanced for optimal reef tank conditions.
Choosing the Best Lightning For Saltwater Aquarium
The best lighting for a saltwater aquarium depends on the types of corals and fish you want to keep. Here is a general guide.
1. Corals
Corals require a complete spectrum of light, including UV light, to live and reproduce. UV-ray is a crucial component for healthy coral and aids in its ability to make the colors it is famous for. Unluckily, excessive ultraviolet (UV) light can be harmful to corals, therefore, a balance is necessary.
2. Fish
However, fish not only need the full range of light but also need specific light amounts for their species. Some fishes prefer the brighter light; others like the lesser one. To pick a lighting system suitable for your fish, it is essential to get familiar with the exact needs of the fish first.
Here are some of the different types of lighting that are available for saltwater aquariums:
1. Metal halide (MH) lights
Deep tanks or corals that need lots of light are the best niches where MH lights should be used. They give all the light spectra, which consist of UV light as well. Yet, MH fittings could be costly, and they develop a great amount of heat, so you might need an aquarium chiller to keep the tank cool.
2. Fluorescent lights
Fluorescent lights turn out to be a cheaper option than MH lamps, and they are available in a great number of colors and light intensities. As opposed to MH lights, fluorescent varieties do not intend to produce the same amount of UV light, therefore, they may not be appropriate for all corals.
3. LED lights
LED lights are a new phenomenon in saltwater aquariums. They save power, only produce less cooling and power compared to MH lights, and they can come in various colors and intensities as well. On the other hand, LED lights may be less affordable than alternative types of illumination.
Are LED Lights Bad For Saltwater Aquariums
No, LED lights do not harm saltwater aquariums in general, rather they come with some specific benefits when compared with fluorescent bulbs.
Benefits of LED lights for saltwater aquariums:
- Energy efficiency: LEDs utilize far less energy than conventional lighting systems, hence, you generate smaller bills and also use less of environmental resources.
- Cooler operation: LEDs make heat less, so the temperature in the water is easier to manage.
- Long lifespan: They have a long life span as compared to other lights and don’t need replacement frequently.
- Wide spectrum: LED Lights can be developed in a way that they produce light of a selected spectrum to bring growth and photosynthesis to corals.
- Reduced algae growth: In contrast with the other lights, the proper LEDs only radiate a limited amount of light in the wavelengths that induce the algae growth.
Potential Concerns With LED Lights
- Sudden light changes: The fast application of bright LEDs can cause corals to turn pale and lose their color. Acclimation is crucial.
- Incorrect spectrum: Although some LEDs are sold inexpensively, they may lack the appropriate light spectrum for the optimal health of corals. Pick brands that are created for saltwater aquariums by professionals.
- Direct eye damage: Any kind of light source, even LEDs that you look at directly, can cause eye damage.
Nitrifying Bacteria and LED Lights
Research is still ongoing, but no proof has been established that LED lights that are properly used harm nitrifying bacteria in saltwater tanks. The dominant wavelengths for the majority of LED lights are not strong enough to destroy these beneficial bacteria. Nevertheless, incorrect light cycles or abrupt changes in light intensity will result in an undesired effect on the overall ecosystem, which would have an indirect impact on nitrifying bacteria.
How to Choose the Best Saltwater Light
Generally speaking, if you are having trouble deciding on the right saltwater light for your tank, many things should be kept in mind. Here are some key points to choose the best saltwater aquarium lighting.
1. Tank Size
The size of your tank is the basis for deciding the type and number of lights to use. If the tanks are larger, then the lights will have to be brighter to cover the whole tank and to ensure the light intensity is the same across the entire tank.
2. Depth of Tank
The dimensions of your aquarium also affect the light you need accordingly. Light fixtures for deeper tanks with higher intensity to reach the bottom of the tanks.
3. Width of Tank
The capacity of your tank will indicate how many lights you will need for a saturated coverage. Lights should be placed closer in wider tanks, with the length of the light sources being slightly increased to guarantee that all tank areas receive adequate lighting.
4. Type of Corals and Fish
Among your lighting options, take into account what type of corals and fish you have in the tank. Corals are often light-demanding, so look for a light that is a good match for your tank species.
5. Light Spectrum
Different lights have different light spectrums, so it’s essential to have that in mind when purchasing a light for a saltwater aquarium. Some corals and fish need to have a specific light spectrum to thrive, so ensure the light source you choose has this spectrum.
The Bottom Line
After all, the lighting system for saltwater aquariums has to be chosen based on the needs of corals and fish. LED lights are the most preferred ones for the reason that they are energy efficient, have a long lifespan and the growth of algae on LED lights is minimal. Despite that, spectrum and acclimation should be given the appropriate consideration to prevent impacts on corals. You need to consider the tank size, depth, and inhabitants when choosing the best lighting for a saltwater aquarium.
