5 Best Led Aquarium Lighting Systems 2019

Last Updated on

Fed up with the early day-glow fluorescent aquarium lights? The freshwater LED lighting is the right choice if you want to enhance the natural colors of freshwater fish. You’ll be able to see all the beautiful colors as well as subtle shades which make freshwater tropical fish real beauties.

As for the aquatic plants, they require full spectrum lighting to thrive in your aquarium. Without the natural light spectrum, which LED lighting provides, your aquatic plants will lose their color over time, drop leaves and die.

In addition, a well-illuminated aquarium, even if it's a starter fish tank, creates the illusion of depth and highlights your aquascaping. If you grow live aquatic plants, you are probably aware of the fact that light quality is very important to sustain their growth. Corals, for example, depend on the proper light spectrum and intensity of light in order to thrive in reef aquariums.

3 Best aquarium lighting options

In addition to the 24/7 feature, the Planted+ has programmed settings which replicate storms, cloudy days, and starry nights. All of these settings are available with a simple click of a button.

best led aquarium lighting: Important Factors

1. The range of light

Led lights in a fish tank for better growth of aquatic plants

Let’s compare LED lighting and the full spectrum of natural lights. Natural daylight, on cloudy to sunny days, ranges from 5500K to 7000K (K stands for Kelvin, a unit of measurement used to describe the hue of a specific light source).

This is why you should look for a LED aquarium light that can provide this range of light quality. LED lights can be controlled by a timer that plugs into the wall. LED aquarium lights can be mounted above the aquarium either on “legs” that rest on top of the aquarium or hang from your ceiling.

The more advanced LED aquarium lights allow you to create light that mimics dawn, dusk, moonlight and more types of light.

2.The dimensions

When you are buying LED aquarium lighting, you need to know how wide your aquarium is. Fortunately, LED light fixtures come in a wide variety of lengths that match the lengths of different aquariums.

This versatility comes into play when you are aiming for a perfect LED light that sits on top of the aquarium frame.

3. LED light features and benefits

As we said, most LED freshwater aquariums feature 5500-7000 K light output. Some have simple and some have a more advanced programmable timer.

Fish tank led lights give a great visual appeal to your tank.

The best LED aquarium lighting will allow you to explore different color combinations because LEDs are now available in a multitude of color spectrums and combos.

Apart from experimenting with light spectrum, you can also use dimmers, which are great for adjusting brightness and can also be used for blending colors. If you are using multiple LED color spectrums, you can dim one color and increase the brightness of the other. By dimming your LEDs, you will also extend the lamp life and save on energy.

Another benefit of LEDs is that they don't transfer heat into the aquarium. However, they still generate a fair amount of heat upward and excessive heat can dramatically degrade the lifespan of the LED chip. Because of this, you should do your best to keep them cool.

To fully benefit from the best LED aquarium lighting and extend their, life you need to make sure to provide adequate air circulation around the LED light strip. This will allow heat to dissipate vertically and around the heat sink.

Yet another benefit of LEDs is that they grow coral so that your aquarium will become a true beauty, should you decide to tackle the wonderful world of coral growing.

In order to really bring out the colors in your coral, you should select units with light output in the actinic royal blue range. This will really make the colors in your coral stand out. For soft polyp corals and zoanthids, you can mix a little magenta to pump up the purple, green and orange.

Apart from growing coral and bringing out their beautiful colors, LEDs will also bring out colors in your fish and make them even more beautiful as they swim happily around the corals.

Best LED aquarium lighting compared to other lighting options

In the early days of aquarium keeping the only lighting available were stainless steel fixtures that contained incandescent light bulbs. These light bulbs produced a lot of heat and raised the aquarium water temperature. As the incandescent bulbs could reach a temperature of over 175° F, the metal light fixture could easily turn into a dangerous skin-searing surface. With the best LED aquarium lighting, this can never happen.

The next type of aquarium lighting was cooler fluorescent light tube housed in plastic fixtures which were built into the aquarium cover. The fluorescent lighting worked fine for shallow aquariums that did not require intense light.

For growing live plants or corals, fluorescent light tubes couldn’t provide enough light. The quality of light was not the best, either. Most fluorescent lights simply highlighted the neon colors of aquarium gravel, plastic plants, and other ornaments.

Live plants and corals did not thrive until more natural fluorescent lights were developed for aquarium use. Fluorescent bulbs, however, start degrading in light quality as soon as they are switched on. After six to nine months, the quality of light gets very low and won’t meet the light needs of freshwater aquatic plants and saltwater invertebrates.

Finally, LEDs use up to 80% less electricity than other aquarium lights. They do not generate as much heat compared to fluorescent light bulbs. Another huge plus is the fact that the best LED aquarium lighting lasts far longer than standard fluorescent bulbs.

The drawbacks

The LED fixtures tend to be a bit more costly to purchase upfront, but you'll more than make up for it over time in energy savings as well as bulb replacement costs.

Another drawback of LEDs is in the area of planted aquariums because most LED light fixtures are only suited for low to medium lighting needs. They will do well for virtually all fish and for a number of plants.

However, for plants that have high light needs, there are no LED lighting options at present. Hopefully, since the LEDs are being extensively researched and greatly improved, we might expect that their application for high light needs will also improve in the future.
