Buyers’ Guide 

What are some factors to consider when purchasing lights for a planted aquarium? 

There are definitely some factors you can keep in mind and decide on before going out to purchase a light for your planted aquarium. Making these decisions beforehand will help you narrow down your search and make the whole shopping process a lot less confusing. Some factors to consider are: 

  • Reliability and Brand 

Obviously, you’re going to want a light that is constructed well and won’t give up on you within a few months. The key is to get a light from a reputable, well-known brand that has been making lights for planted aquariums for some time now. New products can be risky as there are often no reviews of them online and you never know how they’re going to perform. 

  • Build Quality 

It’s difficult to say how the LEDs inside your light will perform many months down the line after you buy them. You can get a good estimate of this by looking up the online reviews for the product you’re intending on buying. 

Other than that, when you go out shopping for a light, do observe its body and the way it’s been made. Make sure the body is made from high-quality materials and the LEDs inside are securely attached so they don’t come loose, etc. 

  • Operating Capacity 

By far, the most important thing you have to think about is how powerful a light you want to get for your planted aquarium. This will obviously depend on what type of plants you have growing inside your aquarium and how big your aquarium is. 

When it comes to lighting aquariums, a good way to measure the operating capacity of a light is by a metric known as watts per gallon. Normally, a planted aquarium requires anywhere between 2 – 5 watts per gallon of light. So for example, if you have a 10-gallon aquarium, you will need to get a light that operates at anywhere between 20 watts and 50 watts. 

Are LEDs the best type of light to get for a planted aquarium? Why? 

LEDs have quickly become the most popular form of lighting not just for planted aquariums but for aquariums of all kinds and for good reason. Some of the benefits of using LEDs to light your planted aquarium are: 

  • LEDs are cost-efficient. LEDs are known to utilize power much more efficiently as compared to their competitors such as incandescent or fluorescent lighting. They use a comparatively low amount of energy to produce much brighter light. 
  • LEDs produce little to no heat. The problem with many other types of lighting such as metal halide lighting is that they produce a lot of heat to the point where you have to invest in a chiller for your aquarium and maybe even an air conditioner for your room. LEDs are known to produce very little heat so you won’t have to worry about the temperature inside your planted aquarium rising. 
  • LEDs are customizable. LEDs can be easily customized and so, many premium lights these days come with a ton of features that let you modify them in an infinite amount of ways such as dimming, brightening, timers, playing with colors, weather effects, etc.

Are cheaper LEDs worth it or should I just save up to get premium lights for my planted aquarium?

We recommend you not to go towards either extreme but to try to find a light that’s somewhere in the middle which caters to all your needs. 

If you opt for an extremely cheap light for your planted aquarium, this would come with a lot of risks. It could break down very soon after you buy it, it may not have many customization features, it may have flimsy construction, etc. 

If you opt for a very expensive light, you may pay a hefty sum of money to get a light that’s packed with features that you’re never going to use. 

How do I set up lights for my planted aquarium? 

Lights are fairly easy to set up since they come with their own instructions which are often very easy to follow. 

Different lights have different mounting methods for aquariums. Some come with mounting legs which are extendable in order to accommodate the size of your aquarium. Others come with hanging kits so you can easily hang them above your aquarium. While others come with clamps or mounting brackets that you use to fix the lights onto your aquarium’s wall.

How long do aquarium LED lights normally last? 

LEDs are known to have a long lifespan. Most LEDs are advertised to last about 50,000 hours. If you keep your LED light on for 10 hours every day then this amounts to almost 14 years. 

Frequently Asked Questions

How many lumens are normally needed by a planted aquarium?

This mainly depends on the types of plants you have inside your planted aquarium. Low-intensity plants require about 20 lumens of light, medium-intensity plants require anywhere between 20 – 40 lumens while high-intensity lights require 40+ lumens. 

How many hours of light do aquarium plants generally require to grow effectively?

Again, the amount of light that plants need can vary depending on their species. 

Generally, most species of aquarium plants require about 12 hours of light every day in order to be healthy and grow at an effective rate.

Does aquarium lighting cause algae? 

Light is actually quite perplexing when you think about how it causes algae and can also be used to control algae. Under different conditions, low OR high-intensity light can cause algae.

If an aquarium has no aquatic plants, low light conditions can favor the growth of algae. 

In a planted aquarium, having too intense light or just having your light on erratically or irregularly can also cause algae. 

If your planted aquarium does end up with an algae breakout and you’re sure it’s been caused due to erratic lighting, you can decrease the algae inside it by placing your planted aquarium in darkness for a couple of days.

Can I keep my lights on for longer than recommended to make up for the fact that they’re not intense enough?

Absolutely not. The only fix for lights that are not intense enough is to replace them with lights that are intense enough. If you subject your plants to increased light hours, this can result in algae growth increasing in your aquarium as well as bleaching of your plants. Not to mention the fish inside your aquarium will also become stressed due to having their aquarium lit for longer periods of time.

Are actinic lights good for plant growth?

Yes. Actinic lights produce light that comes from the blue portion of the color spectrum and this type of light is not only beneficial for photosynthetic organisms like aquarium plants, it’s also very aesthetically pleasing to the human eye. 

Most freshwater planted aquariums benefit heavily from light that lies in the 5500 – 7000 K color temperature range. 

Are white LEDs beneficial for plant growth? 

Yes. The sun gives off white light and white LEDs do a wonderful job of simulating sunlight which stimulates plant growth. White light offers a 40% absorption rate and is definitely beneficial for plant growth. That’s why most LED lighting products for planted aquariums come equipped with cool white LEDs. 

What color of light is best for plants and what color is the worst?

Green light is by far the worst for plants since it has the lowest absorption rate. This is because plants themselves are green because of a pigment inside them called chlorophyll. 

Blue light is very beneficial for plants and they absorb it well. It stimulates growth and vegetation within aquarium plants. 

Red light when it’s combined with Blue lights allows plants to flower. 

Is yellow light good for plants? 

Plant leaves filter light that is most suitable for photosynthesis and only let certain wavelengths of light be absorbed. Yellow and orange light isn’t very necessary for photosynthesis. 

You would be better off using a combination of white, blue and red light.  

Can any LED light be used as a grow light for my planted aquarium? 

You can definitely use any LED light to your planted aquarium and help your plants grow but there’s no guarantee that your plants will grow effectively or efficiently. The LED light you get might not be the right color temperature or right intensity for your plants to grow favorably. Thus, we recommend that you do your research and buy a light that specifically caters to the needs of the plants that you have.

Is ultraviolet light beneficial to plants? 

Plants don’t require and do not utilize UV light in the process of photosynthesis. If you find a lighting product that is expensive only because it has a UV light in it, we would advise you to stay away from it since you don’t really need it if you have a planted aquarium.

Final Verdict 

Aquariums are already tricky to light and when you add aquarium plants to the mix, it becomes even trickier. 

In the end, we have to give the crown to the Beamswork DA 6500K 0.50W Series LED Pent Aquarium Light. It’s incredibly bright but not to the point where it disturbs the fish in your aquarium and it grows aquarium plants brilliantly, all at a reasonable price. 

And with that, we’ve reached the conclusion of our post for the best lights for planted aquariums. 

Let us know what light you’re using for your planted aquarium.
