We aquarium fanatics do a lot to ornate our underwater ecosystems. We put hundreds of dollars in line to purchase the best devices and chemicals to keep the bio-network running smoothly. And the most crucial part of every ecology is the light source.
But, some factors make finding the best LED light for aquarium plants much more difficult than it should have been. The primary reason for this problem is the misinformation that circulates in the online community. Furthermore, electronic products are a common victim of misrepresentation.
So, to clear out all the confusion, we have the complete package here. After going through this article, you won’t need anything more to end your quest for the perfect LED lights.
Here, you will have every detail about the best products currently available in the market and a guide to make your hunt for the best-planted lighting easier.
What Is The Best Light For Aquarium Plants?
If I want to name one single product that satisfies all the needs of an expert aquarist, it would be Current USA Satellite Plus Pro. Go for it if you don’t wanna invest time on the products that you are not going to buy.
This light is fully programmable and hosts eight modes and effects. The PAR value is also excellent although the price might be a drawback. But if you want the best of everything, the satellite plus pro is your choice.
What Kind Of Aquarium Lights To Use
First, let’s look at the options we have. The common aquarium lights are;
- LED lights
- Standard fluorescent lights
- Compact fluorescent lights
- Metal halide lights
- Incandescent bulbs
Now, let’s see which one is the best among them.
Incandescent bulbs are only suitable for small aquariums, and they give off too much heat. Standard and compact fluorescent bulbs used to be a common feature in aquariums as they had a broader light spectrum and good intensity. But they are also falling into oblivion for the increased benefits of LED lights.
The most significant benefit for LED lights is that they are customizable. You can choose the amount of color intensity and the length of your spectrum according to the needs of different plants. Furthermore, you can also program and set the transition time. And all of these benefits and more come at a meager price.
So, LEDs are the future. Period.

10. Nicrew LED Aquarium Light Review
This device is without a doubt the best budget aquarium light in the market. It not only has a low price tag but also has a minimum power consumption saving you a lot of money and benefiting the environment at the same time.
The only major drawback in this device is that it is not waterproof. And, NICREW has done a lot to inform you about this information. So, don’t get it in contact with water. You will instantly kill it. Use a glass base for increased protection.
It has amazing brackets. The metal brackets are very strong, and they can extend to about a foot. The default length of the fixture is 36 inches. But, with the adjustable bracket, you can extend the reach to about 48 inches.
One of its highlights is the high per value in this incredibly low price. The device has two kinds of lights. One of them is bright white, and the other is dim blue. In a one foot deep tank, the PAR value of the white lights is 32 PAR, and the par value of the blue lights are 4 PAR. Without the brackets, the white lights have 36 PAR.
When we called it the best budget light, it was for this PAR value. There is no other product on the market that will give you better lighting in this low budget.
It has adjustable legs. But they are not very strong. The built quality is average and hopefully will last you for a long time if you don’t get into an accident. The band is not that old. So, you can count that as a minus, but they are giving a pretty good service yet.
Check our full review of Nicrew LED Aquarium Light.
- One of the best dollar to PAR ratio
- Low heat
- Lasting lights
- Covers a wide range of the spectrum
- Not UL rated
- You cannot hang it over the tank.
- There is no timer included.
- The product is mostly plastic.
Lighting for planted aquarium – The Basics
Choosing the best LED lighting for a planted tank is half the job. Rest of the performance depends on how you use your gadgets. We have mentioned before that mashing electronics in botanical endeavors is not an easy task.
You will not find much information on it online, and if you do find some, it will hardly be reliable. So, if you don’t have a lot of experience with planted aquariums LED lights, then read this part carefully.
Firstly, you will come across some terms that you might just have a faint idea about. Let’s learn them, heart and soul.
- PAR Value
This metric comes a lot when you talk about LEDs. PAR stands for “photosynthetically active radiation.” The area of the light spectrum that plants use to drive photosynthesis is called photosynthetically active radiation.
Visible light has a wavelength of 380nm to 750nm. And plants can use 400nm to 700nm. So the minimum and maximum range for PAR is 400-700nm.
When buying a light, checkout how much PAR it is giving as that is the primary metric that you wanna follow. Also, try to find out how much of the light spectrum the LED is covering.
The study of different colors or wavelengths affecting different parts of a plant is called photomorphogenesis. For instance, we know that white lights stimulate growth, red light makes the plants tall, and blue light helps the leaves grow more.
If you have a better understanding of it, you will be able to control your pants more comfortably and prevent unwanted growth. Different plants need different wavelengths. Herein, Photomorphogenesis will help you with this too.
There are other advanced terms you might bump in when studying for aquarium plants. But as it is a 101 basic article, I will skip them.
- Consistent Photo-period
This refers to the consistency of lighting. Your plants should have consistent lighting every day. This is by far the most important thing in aquarium farming.
You need to have a timer for maintaining this consistency. Set the timer and transition for accurate light transitions. You also have to calculate the amount of ambient light that the aquarium is receiving and compare it with the natural light for the fish tank to prevent algae and overgrowth problems.
- Intensity Control
The intensity of light is measured in kelvins. Generally, you will find lights from 2500K to 10,000K.
Now, plants don’t care about the intensity that much. What they are looking for is the color of the light. So you don’t have to take a lot of hustle to find the best intensity.
Take one that has 7000K because it looks as the aquarium in direct sunlight would look. Lights below 3000k are cheap but don’t go for them as their power consumption is generally high.
- How does LED lighting work?
The LED lights are not only used to illuminate the tank but also utilized to grow the plants as they are the food of those green creatures. LED lighting is actually a group of small LED lights that have been arranged in a specific order to emit a bright light. It’s basically short for Light-emitting Diode. Basically, the electrons are transformed into photons when the diodes are connected to an electricity source. And these photons are called the packets of energy that are generally perceived as bright light.
The light can have a particular wavelength or color or particular intensity. The lights of different wavelength are connected in sequence so that it can emit a vivid blaze to the tank. And this is how LED lighting works. However, LEDs come with a lot of feature starting from its durability to saving a lot energy. So, you will get many perks from the light once you buy it for your aquarium plants.
- Some Misconceptions
Lastly, I think it’s time to clear out some misconceptions about planted tanks. They are;
- Lumen rating doesn’t have any significant implication on planted aquariums. It tells you how bright your light is, but plants don’t care for that. We measure light in PARs here.
- Plants also don’t care about the Kelvin rating. It is more related to human eyes.
- Watt per gallon doesn’t have any effect on your plants. But you need this metric as it does have a significant impact on your wallet. It tells you how much power the LED consumes to produce light.
- You don’t have to be a nerd to grow plants. You can go to your local supermarket and buy a daylight bulb to start farming. Maybe slow but plants will grow in that condition. When you want to dive into this realm and grow some unique plants, you need all of this studying.
- Just because it is expensive, it doesn’t mean it is good for your plant. Most of the plants will not require costly lights. So, don’t go fancy for them. Most lights work similarly. The difference is between your plants and aquarium.
- Modes and effects like lighting, cloudy, simmering, etc. does not affect plants. They are there for increasing the beauty of your tank.
So, this wraps up all the basic elements of the planted aquarium led lighting guide. I hope, this equipped you well enough to start aquarium plantation with confidence.
Best Light Spectrum For Aquarium Plants
The spectrum basically tells us about the color of the lights. Plants respond very differently to the color of the light compared to human eyes. Plants love the blue and red area of the spectrum and thrive when hit by this kind of light. This plays a crucial role in photosynthesis and, if done right, will result in a beautiful aquarium full of vivid colors.
Watch this great video for more scientific aspects of freshwater aquarium lighting basics –
Freshwater plants thrive under the source that resembles natural sunlight. Anything between 5500K-6500K spectrum is great for freshwater plants. But to make your aquarium look aesthetically pleasing you can increase the color temperature up to 10000K.
Here are the colors that are used for the plants so that they can get suitable lighting atmosphere.
This kind of bulb produces a light spectrum that mimic the sun basically. Its visible spectrum is maintained while the infrared and ultraviolet spectrum are reduced. It owns lots of Actinic Blue and red and helps the plants a lot for growth.
Plant utilizes a particular kind of blue which is known as Actinic Blue. It helps in the growth of plant leaves and stems. This spectrum allows the plants to grow bushy and leafy.
This color is used for creating more viewable light although it is not efficient for thriving plants.
Plants also use Red lights for their growth. Mainly they are important to produce flower and not only that, it also lets them grow taller.
Best Light For Aquarium Plants: Buyer’s guide
Factors To Consider:
- Tank size: You should always buy the LED light according the size of the tank that you own. If you have larger aquarium, you will need the light having widespread intensity and vast coverage.
- Plants type: Different type of plants require different level of lights to grow. If you own plants that are in their growing stage, you will be needing a different level of intensity that might not need at other stages. However, you will get a variety of LED lights for each of their requirement.
- Intensity and Spectrum of light: You might discover a considerable range of spectrum and intensities while you look for the LED lights for your aquarium plants. They are useful for different types of your plants and for their stages of life cycle. Depending on which type and stage your plants are in, you will need to buy the one that will be right for them.
- Substrate and Pressurized CO2: Only high intensity LED light won’t give you the result. For a healthy planted tank you need balance. And to ensure balance you need proper supply of CO2 and best substrate for planted tank.
Always Go For Better Tools: Features To Consider
If you are on a budget and purchasing a light that does not give you an above average performance, then skip purchasing. Save some more and get the superior light in the market later.
You might say that some people are growing plants with backdated equipment, but that is rare and hard to do. The chances are all of your plants will die in your first mistake. So, try to get above average tools.
When you buy your plants from vendors, most likely they will be sitting under state of the art lighting. If your lighting is too distant from their original lighting, then they will all die soon.
Thirdly, when you go out to buy an LED, you need to have a clear view of what are you going to buy and what features you want in what price. So here is a list of attributes you’re gonna be looking for in your aquarium lighting.
As we mentioned before, timers are very important. Ask a person who has forgotten to turn on or off his lights for just one day. It could take months to fix the damage. Even a delay of 10 or 20 minutes can have a vastly negative approach on your plants.
So, a 24-hour timer is a must. Its transition should be gradual and smooth. It is better if it has a sunrise and sunset feature. Some LEDs feature multiple memory options. There you can set and record your transition times, color, intensity, and effects.
An aquarium light is a long term investment. You have to make sure that it will serve you at least for four years.
To ensure that it has to have strong housing, generally, aluminum or good quality plastic is used to make the case. The built quality also has to be premium quality. Faults in design can rapidly cut short a LED’s life.
It also should be waterproof. When electronics are working in water-related environments, they cannot but be waterproof.
You might take it as an insignificant part of your LED. And it is, compared to other more advanced components. But a lousy bracket design can also unleash a world of pain for you.
There are some basic mounting processes. They are;
- Docking legs
- Tank rim mount
- Tank arm mount
- Rimless mount
- Screwed legs
- Hanging design
All of these designs can be either good or bad. But you have to be extra careful about the docking legs. Sometimes, the legs are just a pair of wires. Some might not even have a barrier to stop the legs from coming out of their place. If you have an accident, the LED can easily slide into the water probably destroying it.
Use arm mount with only the lights that have a wide dispersion angle. If your fish tanks are rimless, you must have a rimless mount or a screwed mounting system.
Brackets must also be adjustable. Otherwise, you will be stuck to a particular size and spend extra for a glass base. Glass bases also reduces the performance of your light.
Aquarium Size by LED Coverage:
The coverage of LEDs should always be selected according to the size of the tank. The taller your aquarium is, the more power you require. As for instance, if you light up a flashlight onto the tank, every 4-inch of water will receive the flashlight twice as strong for keeping the same level of brightness.
If you own a large tank, you will need lot of space to light up, hence you will require a light having a vast coverage with widespread intensity. Suppose you own an aquarium that measures about 1 foot deep, you may work out with getting a low-powered fixture and still pull off a medium light. But, putting the same fixture on deeper aquarium will keep you in the lowlight class.
Contrariwise, putting the powerful fixture on the same depth aquarium will emit the light so bright that it will rather become hard for you to thrive plants. And for this, it has always been recommended to have an LED depending on the size of the aquarium.
Frequently Asked Questions
How do you setup LED aquarium light?
How much LEDs do you need for aquarium?
How does the color of light affect the growth of plants?
When should I turn off the aquarium light?
How to program LED aquarium light?
Are LED lights good for aquariums?
Some aquarium lights get the job done nicely like fluorescent bulbs and metal halide lights. But LED lights are ruling the market for the past 4 to 5 years. It is very good with almost all aquarium and plant types. There are a lot of factors that contribute to its success. Some of them are:
- Low energy consumption
- Customizable color and intensity
- Modes and effects
- Low heat output
- Longer life
- Safety from electricity-related accidents
Now, you have to understand that being good for fish tanks and being good for growing plants are not the same thing. The cost is generally high to make an LED to perform well with the plants that need a broad light spectrum.
Do LED lights cause more algae in an aquarium?
Growth of nuisance algae is not linked to all the LED lights. They are related to a particular spectrum of rays that stimulate their growth.
Algae is like every other plant. They use light to do photosynthesis and produce energy for themselves. Every plant uses a particular part of the spectrum. Herein, Algae uses the green and yellow part of the spectrum to multiply their numbers.
So, if your LED has more green and yellow lights, the number of algae can increase. Let’s put it this way, whenever you have excess nutrition in the tank there is a high chance that algae will make use of that extra nutrients (light, fertilizer, co2) and grow. The key factor here is the balance of everything.
How long should I leave my aquarium light on?
Again, it depends on what kinds of plants are you farming. If the plants require more light, then you should go for 12 hours, and if they are the kinds that need less light, then you can do 8 hours. You have to do some research with your plants.
Time would also depend on the intensity of the light. If your light brightness and color are not adjustable, then you need to lessen the time of light exposure. Too much light can cause algae to overgrow and create problems, and too less light means low plant growth. So you have to keep the balance between them.
Even if you get the best LED aquarium lighting for plants, they will not survive under the mismanagement of time.
