[PAR Comparison] Best Planted Aquarium LED Lights – From Small to Large

Updated: August 3, 2025 - By: - Categories: Planted aquarium

Choosing the best LED light for your planted aquarium isn’t just about brightness—it’s about the right kind of light. Specifically, PAR (Photosynthetically Active Radiation) is the key measurement that tells you whether your plants are truly getting the light they need to grow, thrive, and stay lush. But not all LEDs are created equal. Some look bright to the eye but offer poor PAR at the substrate level. In this guide, we’ll compare top LED lights based on real PAR values—from nano tanks to large aquascapes—so you can find the perfect match for your plants, your layout, and your budget.

How Do I Choose an LED Light for My Planted Aquarium?

Several factors must be considered when selecting high-quality LED lights for your planted aquarium. The most critical aspects are the color temperature (Kelvin rating) and PAR (Photosynthetically Active Radiation) measurements of the products.

The Kelvin rating ensures you choose a light with the appropriate white light spectrum for aquarium plants, while PAR measurements confirm the light provides sufficient intensity for plant growth.

The types of plants in your aquarium and the tank’s size are also important considerations.

Kelvin Rating – Choosing the Right Type

color-temperature

Color temperature (wikipedia.org)

The first factor to evaluate is the product’s color temperature, determined by its Kelvin rating. Aquarium plants can adapt to a wide range of color temperatures, but a Kelvin rating of 5,500 to 7,500K is most desirable, as it closely simulates natural daylight, promoting optimal plant growth.

PAR – Ensuring Sufficient Quantity (Most Common and Easy to Use)

PAR (Photosynthetically Active Radiation) refers to the range of light wavelengths between 400 and 700 nanometers that plants use for photosynthesis. It is a key factor in supporting healthy growth in aquatic plants, corals, and other photosynthetic organisms.

LED light manufacturers often provide PAR values for lights designed to support plant growth. A higher PAR value generally promotes better growth, but different species have different light requirements—some thrive in low light, while others require intense illumination.

One important principle to keep in mind is that PAR intensity decreases as the distance from the light source increases. Therefore, high-light plants should be positioned closer to the LED light, while low-light species can be placed further away.

How Much Light (PAR) Do You Need?

Since aquarium plants have varying light requirements, you must determine whether your plants are low-light, medium-light, or high-light species. The following guide outlines the lighting needs for different types of aquatic plants:

How Many Watts per Gallon for Planted Tanks?

If PAR information is unavailable for a light you’re considering, you can use our “watts per gallon” guide for planted tanks. While not as precise as PAR, it provides a relative estimate of light intensity.

Based on the PAR values of many planted tank LED lights on the market, we suggest the following table:

Plant type PAR @ 12-inch depth Watt/GAL
Low-light plants 15-30 0.4-0.5
Medium-light plants 35-65 0.5-0.7
High-light plants 65-120 0.7-1.1

This table applies only to LED lights. For older fluorescent lights, you will need approximately triple the wattage: 1 W/gallon for low-light, 2 W/gallon for medium-light, and 3 W/gallon for high-light plants.

What Is the Best Lighting Schedule for Planted Tanks?

Both fish and aquatic plants benefit from a stable day/night rhythm, just like in nature. Giving them regular periods of darkness helps regulate plant metabolism and reduces stress in fish.

If you’re unsure where to begin, a natural light cycle is a safe and effective choice.

Nicrew SkyLED Plus Automatic light cycleNicrew SkyLED Plus Automatic light cycle #ad

The schedule above is a great example to follow—especially if your lighting system doesn’t support 24/7 automation. It simulates sunrise in the morning with soft white light, increases to full intensity at midday, gradually dims by late afternoon, transitions to gentle blue moonlight in the evening, and turns off entirely at midnight.

No 24/7 Mode? Here’s a Simple Manual Setup:

If your aquarium light doesn’t feature a built-in 24-hour cycle or variable intensity, you can still create a healthy lighting routine by running the white light for 8 to 10 hours per day.

Try one of these proven time frames:

After your main lighting period, you can turn the light off completely—or, optionally, leave on the blue LEDs only for a few extra hours to simulate moonlight. Make sure to turn off all lights by 12:00 AM to give your tank complete darkness overnight.

Blue LEDs used for moonlight are dim and calming, and won’t interfere with fish behavior or plant growth when used for a short period.

Frequently Asked Questions

What Happens to Planted Tanks Without Light?

Without a light source, aquarium plants struggle to photosynthesize—a process essential for their survival. While all plants need light, the amount required varies by species.

Some low-light plants can survive on ambient natural light from a nearby window. However, most medium- and high-light plants will slowly deteriorate without proper artificial lighting, leading to yellowing leaves, stunted growth, or die-off over time.

Why Should I Use a Light Timer?

A light timer helps maintain a consistent day/night cycle for your plants and fish. This not only supports healthy plant growth but also prevents overexposure to light, which can cause algae blooms. Timers also make maintenance easier by automating your lighting schedule, ensuring plants get the optimal duration of light daily—typically 6 to 10 hours, depending on the setup.

What Happens If There’s Too Much Light but Not Enough CO₂?

Light and CO₂ must be balanced in a planted tank. When lighting is intense but CO₂ levels are low, plants cannot keep up with the increased energy demand. This imbalance allows algae to take over, as it thrives in high-light, low-CO₂ environments.

On the flip side, injecting too much CO₂ without sufficient light means your plants can’t use it effectively, and excess CO₂ may harm fish and invertebrates.

Where’s the Best Place to Buy Aquarium Lighting?

Online marketplaces like Amazon are a great place to start. They offer a wide variety of planted tank lights with different features, sizes, and price points, making it easier to compare and choose what best suits your aquarium’s needs. For large tanks or demanding plants, be sure to check product specifications like PAR output and coverage area.
