Best LED Grow Lights of 2022

Written by twitiq

Green plants need light to make photosynthesis happen. In this process, a few cells convert the energy contained in the light into sugars. After that, the plants give off oxygen. But the amount of light required depends on plants, including low-light houseplants ( dracaenas), fruiting edibles ( tomatoes), etc. Seedlings usually need plenty of bright light. Therefore, they become weak and leggy if they don’t get it. Mostly, the sunniest windowsill cannot offer the intensity or duration of light required, especially in winter. A best LED Grow lights can helps the plant by doing the function of Sun.

What Are LEDs, and How Do They Work?

These are tiny electronic components consisting of two various types of semiconductor material. One material has a negative charge, known as electrons, whereas the other has a positive charge, called holes.

If you apply voltage over LEDs, electric current begins flowing through them. As a result, electrons and holes begin colliding, due to which it releases energy in the form of photons, light quanta, a process called recombination. Previously, these came with low light output and limited selections of colors, whereas modern ones offer high brightness. Besides, the latest models are available in many colors. In addition, you can get them in different ranges, including visible, infrared, and ultraviolet spectral.

What Are LED Grow Lights?

LED grow lights refer to luminaires. These Grow lights use LED chips in a modern way to generate light for growing plants. These Grow lights are available in multiple shapes and sizes. Besides, the chips offer the most effect on the spectrum (colors) and photon flux (“brightness”). Manufacturers can select which they use in their lamps as they need to know the type of devices which can fit the specific application. These can fulfill the light to the requirements of plants, but the traditional lighting solutions don’t.

What is the Effect of LED Grow Lights on Plants?

A few colored models have a direct connection to the intended purpose. According to some studies, a few specific colors can influence plant growth, affecting root and flower formation. For example, it indicates that most plant sorts complete a normal growth cycle while exposed to blue and red models. Adding other colors to the spectrum like green, far-red, and deep-blue will help you add the process.

A spectrum containing all colors is known as a full spectrum, and it looks like the sunlight. When it has high proportions of green, you will see white light. LED grow light’s full spectrum help to make a visual inspection of the plants possible.

Which One Will You Use— LED Grow Light or Fluorescent Grow Light?

Both can create full-spectrum light. However, it is better for plants, the environment, and your wallet than fluorescent. These are perfect for plants and can fulfill the proper needs of indoor plants. It can enhance photosynthesis and make sure peak growth. In addition, these give off very little heat.

These cost a bit more but are super-efficient. Besides, these take the help of half the electricity and can last five times longer than fluorescent bulbs. Moreover, these are earth-friendly. Mercury-free tubes usually do not shatter like glass. As a result, a few ones end up in landfills.

On the other hand, Fluorescent ones come at a reasonable price. Therefore, these are a good option if you are a beginner at indoor gardening or grow just a few plants.

Types of LED Grow Lights:

These are available in different forms. When you learn about the most famous ones, it helps you to select the correct type for your indoor garden.

Spread-Style Grow Light:

These come with multiple small individual lights which can spread out over the whole surface area. It helps to offer light to a large number of plants. The spider-style and quantum board are the two major subcategories of these types.

Smaller Spaces Convenience:

You can set them closer to the plants. However, the growing space should not be extremely high or wide.

Energy Efficiency:

Using them, you can optimize the spectrum while concentrating energy on the wavelengths. These are lucrative for every application and plant. Moreover, the decreased heat production lets you put LED fixtures near plants, ensuring that you have lost less light elsewhere.

Fire Safety:

You can use them safely as these don’t become warm as the conventional HPS lamps.


Mostly, HPS lamps use the full light intensity, whereas these dim. It is possible with a remote control or via an app. As a result, you can handle it easily apart from consuming less power.

Better Crops:

LED grow lights for seedlings can generate better crops to get bigger plants and allow them to grow fast than the HPS ones. In addition, these consist of a spectrum aimed at a specific goal, including anthocyanin accumulation, flowering inhibition, enhanced rooting, etc.

More Environment Safety:

These emit less heat. Besides, you can add UV light to these lamps, reducing bacteria and mold formation probability. It indicates that you will have fewer pesticides and less environmental pollution.

Best LED Grow Lights Buyer’s Guide:

Go through these aspects before purchasing the best LED grow light. It helps you to make an important decision.


Manufacturers use different metrics for power measurement and light amount. Therefore, it is pretty challenging to compare them. Lumens are the unit of measurement of brightness. For example, seedlings usually need about 2,000 lumens per square foot to thrive, whereas flowering plants can require 10,000 lumens.

It can measure visible light. However, biologists can take the help of the photosynthetic photon flux (PPF) or its density to measure light intensity absorbed by indoor plants. You can measure PPF in μmol/second (or micromoles per second), and it is photons number of light emitted every second.

You can measure PPFD in micromole/m2/s, distributed per square meter per second. Try to use a model with higher PPF and PPFD to get more effective use.

Heat Output:

While using these models, the heat the bulbs emit may damage your plants. In this case, you should use LED types. These give off little heat compared to the amount of light they generate. However, they create some heat, for which you can find multiple models featuring built-in cooling systems to ensure proper temperature regulation.

A few models contain aluminum heat sinks, whereas a few contain fans. In this case, a fan can be loud. Therefore, you must consider noise levels while choosing such models.

Coverage and Wattage:

If you’re willing to select the correct model, you have to know the coverage required of you. In this case, your job is to group plants together and then measure the square footage. Mainly, these list the area of coverage.

If you want to set up the amount of electricity a light uses, you must find its “actual power draw” or “actual power consumption.” Then, you can measure it in watts, letting us know about the power. However, you should not use bulb wattage as it isn’t a good indicator. These are manufactured and designed primarily to be energy efficient.


There are many models designed to link to other units. These help to cover more extensive areas, like “daisy-chain connectivity.” If you use a model with such ability, you need to connect it. After that, your job is to connect it to one outlet, reducing the number of cords required for setup.


Ensure that the product you will buy must have adjustable features.


Plants usually require different color lights in every life cycle step. You should choose the best model to provide you with red, blue, and white color options.


When it comes to color adjustability, these come with knobs to adjust the brightness of their bulbs.


You can increase the length of the rope/ chain or reduce for adjusting the distance between plants and lights.


These enable you to mount to the ceiling with a chain or rope. But you may need thirty minutes to install it or a couple of hours.
