Aquarium Lighting:
Choosing The Best Lighting for Your Needs
Aquarium lighting is very important for the health and vibrancy of your aquarium plants. This guide will help you navigate through the various options, from LED to fluorescent lights, and provide insights on energy efficiency, color spectrum, and intensity to ensure your tank thrives.
In this article, we're going to discuss:
Importance of proper Aquarium Lighting
Proper lighting and spectrum are essential for a successful aquarium.
LEDs are the best freshwater planted lights these days because they offer great functionality and customization.
Choosing the best LED lights for planted tanks can be difficult because there is so much information available, but we are sure this guide will help you understanding the most important things.
Types of Aquarium Lighting
LED Lights for Aquariums
Light Emitting Diode (LED) technology has revolutionized aquarium lighting. These lights are energy-efficient, customizable, and provide a long-lasting solution for your tank. They allow you to mimic natural lighting conditions and enhance the color vibrancy of your aquatic inhabitants.
Furthermore, LED technology has seen significant advancements in recent years. Modern LED fixtures often come with programmable features, enabling users to create customized lighting schedules that mimic natural day-night cycles. This level of control not only benefits the aesthetic appeal of the aquarium but also supports the overall well-being of the aquatic life.
Fluorescent Aquarium Lights
Fluorescent lights have been a staple in aquarium lighting for years. They offer even and widespread illumination, making them suitable for a variety of setups. Understanding where fluorescent lighting excels and how to maximize its effectiveness is crucial for a thriving underwater environment.
Energy Efficiency and Cost Considerations
Evaluating Energy Consumption
Different types of aquarium lighting have varying levels of energy efficiency.
LED lights are known for their low energy consumption and long lifespan, making them a cost-effective choice in the long run. They also produce less heat, reducing the need for additional cooling equipment.
Fluorescent lights have a higher energy consumption compared to LEDs.
Long-term Cost Analysis
When considering the total cost of ownership for aquarium lighting, it’s important to factor in not only the initial purchase cost but also ongoing expenses such as bulb replacements and energy consumption. LED fixtures, despite their higher initial investment, often prove to be more cost-effective over time due to their long lifespan and energy efficiency.
Additionally, the reduced heat output of LED lights can lead to savings on cooling costs, especially in larger setups or in warmer climates. Conducting a thorough cost analysis will help you make an informed decision based on your specific budget and long-term goals.
Color Spectrum and Kelvin Ratings
There isn’t much information available online about the spectrum of planted tank lights, which is really disappointing given the number of LEDs on the market.
The goal of planted tank spectrum is to have a balanced spectrum with a focus on reds and blues because plants need that kind of colours to grow.
The spectrum is deficient in reds and blues in many LED models on the market.
You want 40-70 percent of the light to be in the red and blue spectrums.
Most manufacturers strive for a 6500K spectrum light.
While this is the standard, we will discuss other factors that are important in this article for example the light’s spread and intensity. The Kelvin rating is simply a visual assessment of the light.
Kelvin ratings serve as a measure of the color temperature of light. In the context of aquarium lighting, lower Kelvin values (e.g., 6500K) produce warmer, redder light, while higher Kelvin values (e.g., 10,000K) result in cooler, bluer light.
Experimenting with different Kelvin ratings and observing how your aquatic life responds can help fine-tune the lighting conditions for optimal health and vibrancy.
Lighting Duration and Intensity
In order for plants to thrive, they require a specific level of intensity, which can be quantified using a metric known as PAR. These PAR levels can be categorized into the following groups:
A common practice is to start for a new aquarium set up at 6-8 hours and provide later on max. 10-12 hours of light per day, allowing for a consistent and predictable lighting schedule.
Fine-tuning light intensity is equally important. Different species have varying tolerance levels to light intensity, and excessive or insufficient light can lead to stress or suboptimal growth. Observing the behavior and appearance of your aquatic life can provide valuable insights into whether adjustments are necessary.
Intensity Measurements With PAR
Setting the ideal photoperiod, or the duration of time that the lights are on, is crucial for regulating the biological rhythms of your aquarium inhabitants. Most aquatic organisms have evolved to follow a day-night cycle, and replicating this cycle in your tank helps maintain natural behaviors, such as feeding, resting, and reproduction.
Low Light Plants
25-50 PAR This is best suited for shaded aquarium plants or plants that require little light to low light, such as Java Moss.
Medium Light Plants
100-150 PAR
You can grow any available plant with this intensity level of light and proper C02 regulation.
However, red-colored plants may not produce the best coloration.
Carpet plants like Eleocharis Dwarf Hairgrass or Monte Carlo thrive in this “medium” light level.
High-Intensity Light Plants
150-250 PAR
This level of opacity is ideal for red aquarium plants like Rotala Macrandra.
This lighting intensity allows for high plant density and reduces shading from larger plants.
Because of the increased intensity of the light, more maintenance is required to prune down and fertilize your plants to control algae issues.
Evaluating from easy to advanced
Another method is to choose the plants according to the following table:

Aquarium Light Spread
Spread is a major issue in densely planted tanks because taller plants shade smaller plants as they grow.
If you use a single lighting source it is possible to have a very high PAR level in certain areas of the aquarium while leaving edges or shadows dark. To avoid this its recommended to buy a proper leight in length and width and take it in consideration when planting your aquarium.
Plant Considerations
Optimal Lighting for Freshwater Plants
The best LED light for aquarium plants is a full spectrum RGB light.
RGB lights represent three different colors: red, green, and blue.
These lights are especially important for red plants because they show more color.
For freshwater planted tanks, achieving the right lighting conditions is crucial for the health and vitality of aquatic vegetation. LED fixtures with a color temperature of around 6500K are often recommended, as this closely resembles natural sunlight and supports photosynthesis. Additionally, it’s important to consider the light intensity, ensuring that it reaches all parts of the tank to promote uniform growth.
Addressing Challenges in Plant Lighting
One common challenge in plant lighting is finding the right balance between intensity and duration. Too much light can lead to excessive algae growth while insufficient light can hinder photosynthesis and lead to poor plant growth. Regular monitoring and adjustments are essential to address these challenges and ensure a healthy and balanced ecosystem.
Will Normal LED Lights Grow Plants?
They will grow plants, but not in good their best condition.
The amount of PAR emitted by normal white LEDs is their main strength, as white lights emit the most intensity for human eyes.
However, white lights will not produce as much plant growth as a light designed for planted tanks, such as an RBG light.
How Long Should I Keep My Lights On For Plants?
Depending on how mature your set up is, it is recommended to start with 6 hours and increase the duration to prevent algaes. Once your aquarium is mature enough its possible to keep your lights on for 8 to 10 hours per day.
