Best Aquarium Led Lights

I have noticed this pattern in general people about lights in aquariums being taken as decorative pieces. Rest assured, they are not. If you have been following our site then I am quite sure you know by now that lights hold a very important place in an aquarium’s ecosystem.

But just because you know it is necessary, it shouldn’t mean you just hop on your bike and just go buy a LED light system for your aquarium. In this article, we will tell you why you specifically need LED lights, what are the options available to you in the market, and which one will fit your needs to a T. So strap up your seatbelts for another informative review article.

Why Do You Need Led Lighting In Your Aquarium?

By now, I hope we have established why exactly are lights necessary in an aquarium. Lights simulate and mimic the natural environment that the fish live in. In the wild, the fish live in environments where sunlight plays a huge role. In the aquarium, lighting systems replace that role. Lights set up day and night patterns helping set up the circadian rhythm. In fish like Goldfish and Betta fish, light is responsible for coloration, the establishment of eating habits and light helps fish produce Vitamin D which keeps them away from many diseases. But let us see why exactly we need LED lights.

  • LED lights when of good quality produce lights of different intensities. This provides the fish in the tank with lights of all wavelengths just like sunlight would, mimicking their natural habitat.
  • Unlike fluorescent tubes Led lights do not contain gaseous elements inside them. This not only reduces pollution inside the tank but also is environment friendly.
  • As compared to other light sources, LED lights are extremely energy efficient and save you a lot of electricity bills.
  • The life span of a LED bulb is fixed and is longer than other kinds of bulbs. This way you have a general idea when exactly you may need to change the lights.
  • LED lights are made to be automated. They are easy to be remote-controlled, dimmed, or made brighter without much of a hassle. 
  • Unlike Tungsten bulbs or other high energy output bulbs, these LEDs do not increase the temperature of the surrounding that much as they release very little heat energy.

How To Choose The Right Led Lighting For Your Tank?

Size of the tank

Like with everything else that is related to an aquarium, the size of the aquarium also affects what kind of LED you should choose for your tank.

The larger your aquarium is, the more light you will need. If you have a very large aquarium, you have to choose an LED that has higher lumen i.e. higher brightness as well as higher intensity. Our suggestion is that, instead of choosing one powerful LED for a huge aquarium choose 2 LED lights of half the power so that your tank can be illuminated evenly.

Types of plants in the aquarium

Almost all green plants require light for photosynthesis. But different kinds of plans have different requirements for light. And hence, plants in the aquarium affect the choice of the lights.

There are some plants that are considered to be easy to maintain for example Anacharisa, Sagittaria, Vallisneria, Ambulia, Amazon sword plant. Such plans have a lower requirement of light energy part-time per liter of water. On the other hand, other kinds of larger plans which have a higher requirement of light energy will make you want an LED lighting system that dissipates higher energy.

Types of fish in the aquarium

Different types of aquarium species need different light requirements to thrive. So the first step would be to choose which species of fish you want to keep and then to determine their lighting needs. You will need to research the requirements of the specific subspecies you add to the aquarium before choosing aquarium lighting and that ensures the light will produce the correct amount and type of light that is required by the subspecies.

Most of the fish that we keep in the aquarium come from freshwater sources like rivers, streams, or clear lakes. These fish are used to bright sunlight and warm rain forest weather. So, they will need lights that can produce brighter energy and at the same time, they also need darker places to hide from the light.

On the other hand, a bright light is not always a good choice. Some fish in the aquarium come from bottom-dwelling species of murky flood plains and they enjoy a dimmer environment.

Features and budget

Of course, it goes without saying that you should look at the price of the aquarium before you actually buy it. But, this is not something to worry about as we have in our list gathered the best-LED lights present in the market, detailed their features, and also given you the price range so that you can select the best available option for yourself.

The actual LED lights are enclosed in an aluminium shell. This lends durability to the entire fixture by easily dissipating excess heat produced and extending the life of the lights. The aluminium housing also makes it somewhat water durable.

What is an LED light? How is it any different from other lights?

LED refers to Light Emitting Diode. While traditional light bulbs produce light energy with the help of current passing through some metal strip or wire, LED bulbs to use diodes. The current converts the electrons into electricity in the diode. This allows the LEDs to be more energy-efficient, lasts longer than other lights, and also produces more natural eye-soothing light.

How much LED light is required for an aquarium?

Well. What a weird question. The question should be how much energy per time do I need for my aquarium. That depends upon the fish and the plants you have in your tank.

If you have easy plants the range is between 0.25 to 0.5 Watts per litre.

If you have plants that have higher photosynthetic requirements, you will need more than 1 Watts of light energy per liter.

Will my plants grow under LED lights?

The growth of your plants inside your aquarium does not really depend upon what kind of bulb you’re using in your tank. The growth of your plant depends upon whether it is provided with adequate light or not and whether it gets wavelengths from different spectra of visible light or not.

This means that your plant requires red light, blue light, white light which have different wavelengths, for photosynthesis. The absence of one of the presence of only one decreases the rate of photosynthesis in your plants and hence affects their growth. LEDs are lights that produce electricity through the diode.

Hence, your answer would be that yes, aquarium plants grow under LED light, provided that you choose the correct LEDs.  There are many LED lights listed in our list above that produce full-spectrum lights and help grow the plants to their full potential.

Should I turn my aquarium lights off or should I keep them on always?

The answer to this may be a bit complicated. The whole idea of having lighting your aquarium is to mimic the natural light and dark conditions that are present in the wild. In the wild, the sun rises in the morning and sets at the night and this continuous cycle of lightness and darkness results in various physiological processes. Sleep and wake up pattern, feeding pattern, behavioural pattern are dictated by light periods. Hence, the presence of darkness that is night time is as important as the presence of brightness. Hence, if you have simple basic lighting in your aquarium then you must turn them off for at least 8 hours in a day. The timing of turning off the lights may depend upon the amount of plant you have in your tank.

However, many of the lighting units featured in a list have a pre-timed and automated night light system. This system produces cool blue hue after moonlight replicating the night time. If you have such advanced and sophisticated lighting systems you may not need to turn off your light.


Hence we can conclude that among all the lighting options present in the market, LED lights to provide the best in terms of quality of light, the best efficiency, and are also one of the longest-lasting bulbs.

There are many factors you should consider before going into the market and buying a lighting panel, which we have covered in this article. And we have also provided you with a list of options so that you can select the one that is best suited for you. As per our opinion and experience, we would not shy away from suggesting anybody the NICREW Classic LED Aquarium Light with Extendable Brackets as the best available option for a moderate budget.
