doesn’t have that many head-turning features but it’s a solid lighting setup.

Planted Aquarium Led Lighting Guide – How to Choose the Best Light for a Planted Aquarium?
Choose the Right Brand
When shopping for aquarium lights, you might see many small brands offering cheap lights stacked with features.
Even I have fallen victim to this trap. I was excited to see some unknown brand offering premium grade features in a cheap light.
Listen to me – STAY AWAY from these!
There are a number of issues with these cheap, unknown brands.
Most of the time, they will lie about their specs to pull off marketing stunts. Even if you get the correct specification, there is no guarantee that the light will last for a long time.
Furthermore, these manufacturers offer low-price products by using cheap materials. What is the end result?
Often, the light overheats and increases the temperature of the whole aquarium. Sometimes, it can break off and your fish can fall victim to nasty accidents.
It’s always better to choose a product from a well-known brand. These brands have a responsibility to their customers and a legacy to maintain.
That’s why they never make false claims or do ridiculous marketing stunts.
Finnex, Current USA, COODIA, Beamworks, NICREW, Hagen, etc. are some of the more notable brands in the aquarium light industry.
For a planted tank, a good light setup is a must. The plants need light to conduct photosynthesis.
But plants react differently to different colors of lights. You should know that the white light spectrum consists of an infinite number of colors.
The chlorophylls in the plants absorb mostly violet-blue and orange-red wavelengths.
Therefore, you should check the specification of the aquarium light and make sure it offers mostly blue and red lights. You should also check the wavelengths of these colors.
Your plants won’t get any benefit if the light doesn’t consist of the desired colors and wavelengths.
Remember, your goal is to promote the photosynthesis process so that your plants can make enough food and maintain steady growth.
Control Features and Modes
These two are relatively new features which you can find in the newer varieties of light setups. So, what do they mean?
First, let’s start with the modes.
In nature, light intensity doesn’t remain constant throughout the day. For example, the light intensity is soft and sweet at dawn and during the morning.
The intensity gradually increases and reaches its maximum level somewhere around noon. Then, in the afternoon and dusk, it dims slowly.
To mimic this natural light intensity, some brands offer modes. They have different modes which mimic sunrise, daytime, sunset, and even a starry night.
Such a change in intensity doesn’t only enhance aesthetics but also helps the plants and the fish to maintain a healthy daily cycle.
Now, let’s take a look at the control features.
This simply means user-friendliness., for example, the light might come with a remote-control system to set a preferred lighting scenario.
Some companies even offer programmability which allows you to set a customized light controlling system.
These advanced features make a huge difference and put a product above others.
The Ease of Installation
No one wants a light which requires great technical knowledge to install. Simplicity is majestic.
The easier the installation process, the better. Everyone should be able to install a simple light without seeking professional help.
I would say that this is one of the most basic features to look for in a light.
Sliding-docking system, suction system, and attachment clips are some of the easiest and most basic installation processes.
When buying a light, make sure that you fully understand the installation process. You can even watch some tutorials online.
Make sure you do a proper job.
Durability of the LEDs
This is a feature which doesn’t require any instruction. Whichever light you buy, it should be durable and be able to serve you for a long time.
Almost all the notable brands give an estimation of the lifetime of their LED bulbs. 10,000 hours seems like a good lifespan to me.
It’s not mandatory for your light to have a 10,000-hour lifespan, but it should be around this number.
You certainly don’t want your light to stop working within a few weeks, do you?

Ventilation and Splash Guard
As an aquarist, you should be aware of the impact of heat in an aquarium. No matter what, you should try to keep the water temperature at a constant level.
Otherwise, you may suffer a lot of problems.
As you will be keeping the light on for a long time, it’s only normal that it will heat up.
But a good light setup should have a sound heat ventilation system so the heat can dissipate through a diverting channel.
There are multiple ways to dissipate heat from the light – heatsinks, fans, insulating material, and so on. Then comes the splash guard.
A splash guard works as a barrier between the water and the naked light.
Without the presence of a splash guard, the water can reach the electric panels and nasty accidents may occur.
It’s a simple yet crucial feature to have.

The Kelvin Rating
A lot of new aquarists often ignore this feature, but this is one of the most important factors that makes a light setup good or bad.
So, what is the Kelvin rating?
The Kelvin rating indicates the warmth of the light. As you know, light can be either cool or warm. Cooler light appears bluish and warmer light has a yellowish tone.
On the Kelvin scale, the lower the Kelvin rating is, the warmer the light will be.
For example, 2000K to 3000K color temperature is very warm. This sets an orangish-yellow tone.
On the other hand, cooler light has a higher Kelvin rating. 4600K to 6500K rating indicates a very cool color and it appears white or bluish. Remember, white or blue light for an aquarium is very important!
Most big brands offer super bright 6500K white light.
However, there are some controversies regarding the importance of the Kelvin rating on the photosynthesis process.
FAQ – The Best Light for a Planted Tank
What Is the Best Light for Aquarium Plants?
This depends on a number of factors. As I have stated above, my vote would be for the Finnex Planted+ 24/7 LED KLC Aquarium LED Light.
My reasons are simple – it provides versatility, controllability, and customizability.
There are different modes to offer vibrant living condition, and you can control the light using a remote- control system.
The colors are bright and offer a multicolor blend. You also get extra safety with the sensor system and the water-resistant coating.
Overall, it’s a great buy which offers tons of features.

What Size LED Light for an Aquarium?
The size of the LED will eventually determine the size of the whole lighting setup. Furthermore, the size of the light should match the size of the tank.
As you can imagine, there are many things you should consider in this case. But first things first, what is the total watt demand of a tank?
Ideally, you should allocate 1 to 3 watts per gallon of water. So, according to this rule, if you have a 10- gallon tank, your light setup should be able to offer 10 to 30 watts in total.
However, there are some plants which demand more light. These are special cases.
So, it doesn’t matter what the size of each individual LED bulb is as long as you get the proper watt count.
However, there is another crucial factor which you shouldn’t forget.
LED lights for planted freshwater aquariums are way more efficient than traditional CFL lights. For example, an 18-watt LED bulb provides the same result as 175-watt CFL lights.
Most light manufacturers have a chart or guideline that will help you choose the correct size. So, just stick to their suggestions and you will be good to go.

How Much LED Lighting is Needed for a Planted Tank?
As I have said, the light intensity depends on the size of the tank and the type of plants you are keeping in it.
Not all plants require the same amount of light.
Offering more light than necessary is equally as bad as offering low light to plants. Both can be lethal! The following table should help you out:
So, rather than prioritizing the number of LED bulbs or the size of the LED bulbs, you should give priority to light intensity or lumen count.
How Many Hours of Light are Needed for Aquarium Plants?
Different plants require a different amount of light and the amount of light is also dependent on seasons.
So, you can get a specific answer after choosing the species of your desired plant.
For example, Amazon Sword demands 2-watts per gallon and full spectrum (5000K to 7500K) light for 10 to 12 hours every day.
On the other hand, Anubias demands 2-3-watts per gallon and full spectrum (5000K to 7500K) light for 8 to 9 hours every day.
You can’t simply follow a generic rule in this regard.
If you want to see your planted aquarium thrive, make sure to study the plants and their individual light requirements.
