Best LED Grow Lights Of 2021

Quick Navigation

When you make the decision to invest in your indoor grow, you'll definitely want to learn about the best LED grow lights.

LEDs are regarded as some of the best indoor grow lights on the market, but there are so many out there that it can be tough to weed out the cheap, unreliable brands and models from the legitimate ones.

And with the price of some of these grow lights, it's crucial that you do your research before purchasing.

Before you buy an LED, you should make sure its the right light for your grow.

Before we get started with our list of the best LED grow lights, we need to cover some basic information on this technology.

What are LED Grow Lights?

LED stands for light-emitting diodes. LED grow lights have rapidly come down in price and home growers everywhere are starting to make the switch to solely using them as their lighting option.

These lighting systems produce extremely low heat, come ready to plug-and-play, and can produce high yields with incredible energy efficiency.

Whereas HIDs require a reflector and ballast for operation, LED lights do not. They can last for decades, whereas HID bulbs will often need to be replaced every couple of years. But, one of the main reasons LED grow lights are regarded as the best is due to the spectrum they produce.

Different types of LED grow lights

LED grow lights are available in different forms, so let’s look at the pros and cons of each so you can find the right LED light for you:

LED Grow Light Panels

Panels are the most common type of LED grow light and most of our list will consist of LED panels.

They include heatsinks for removing heat, a driver (think of it as a ballast), and often come with a warranty.

When you think of LED grow lights, you are more than likely thinking of an LED panel, as these are the only type of LED really suitable for full state growth.


  • Full spectrum with switches for both the vegetative and flowering stage - can be combined
  • Comes ready to plug right into a standard house outlet
  • Incredibly long lifespan - the bulbs typically last for decades.


  • Most expensive type of LED grow light

LED Grow Light Bars

Many growers add LED bars as an easy way to expand their lighting footprint or change up their light spectrum. LED Bars are a single row of diodes that come in different spectrums.

You typically wouldn't use an LED bar to grow a plant from seed to harvest. Instead, think of these as supplemental lighting to a main light source (maybe HID).


  • Can replace T5 fixtures for increase PAR and less energy consumption
  • Some units come plug-and-play and can work with a standard 120V house outlet


  • Usually only one spectrum with no switching options
  • Can usually only be used for supplementing, and multiple bars will need to be purchased if using as sole light type

LED Grow Light Bulbs

An LED grow light bulb is exactly what it sounds like - a single LED bulb. Similar to LED bars, you wouldn't want to use one of these to grow plants through flower (usually).

But, they can be a great way to grow small leafy greens or start plants with a full spectrum. You can quickly replace all your old CFL bulbs with LED bulb, which will give you all the added benefits of LED grow lights.


  • They will fit into a standard light socket
  • Great for mixing and matching for creating your preferred spectrum


  • Multiple bulbs required
  • A reflective hood may be require

What makes the best LED grow light?

The best LED grow lights have a few things in common - a uniform spectrum, efficiency, high-power, and reliability/durability.


The best LED grow lights have a uniform spectrum, so if you have 4 plants under your light, they all get the same spectrum.

We already touched on spectrum a bit, but its important to reiterate that the best spectrum consists of not just red and blue light, but also infrared (IR) and Ultraviolet (UV).

Full spectrum LEDs allow you to grow from seed to harvest with the same light, as opposed to having to replace bulbs or use different grow lights for veg/flower.


The more light your LED actually gives off, the bigger yields you’ll get (for the most part). So, the best LED grow lights need to be incredibly powerful.


In general, LED grow lights are very efficient. But, the best LED grow lights tend to also be the most efficient. Operating at a high level, producing high power, and maintaining a low cost to run is very important.


Given the cost of LED grow lights, they need to be seen as an investment. Obviously, your investment needs to last you a long time for it to show a return.

Therefore, the best LED grow lights are reliable and durable, standing the test of time.

All of the lights we will be listing are from the most reputable brands and include some sort of warranty. This will give you peace of mind when you purchase, knowing you are protected.

Best Beginner LED Grow Light

When just starting out, you may not need the most powerful grow light, or even the best all-around grow light.

But, that doesn't mean you should buy some cheap Amazon LED that is going to disappoint you with a lackluster harvest.

Covert LED-X 250 Watt Full-Spectrum LED Grow Light

Best beginner LED grow light

The all-new Covert LED-X 250 watt grow light provides a full spectrum of high-powered LED light without costing an arm and a leg.

The modern open bar design minimizes heat and reduced hot-spots on your plants, while creating an even light footprint.

This is the best beginner LED because it features many of the same benefits of top-tier lights without the huge price tag. It costs just around $10 a month to operate, and is great for tents sized from 2' x 4' all the way to 4' x 4'.

From a spectrum standpoint, it features a perfect blend of white LEDs and far-red LEDs, contributing to the perfect spectrum for all phases of growth. The Covert LED-X is also very powerful, putting out 525 µmol s-1, and achieving an efficiency of 2.1 µmol s-1 per watt.

The Covert LED-X 500 Watt Full-Spectrum LED Grow Light

If you want this light in a bigger tent or grow room, check out the Covert LED-X 500 Watt LED Grow Light. It brings all the same value in a slightly larger, more powerful fixture.

This version of the LED-X series puts out an impressive 1050 μmol/s at 2.1 μmol/s, making it both powerful AND efficient. Just like the 250w LED-X, it puts out a full-spectrum white light with enhanced red (Seedling to Flower).

With the optional Covert Master Lighting Controller, you can manage on/off times, set a high-temp shutoff point, dim the light up to 50%, and control 2 separate zones or rooms.

Most Powerful LED Grow Light

When it comes to power, there are some incredible LED options. This was a tough choice because there are lots of very powerful LED grow lights, but one stood out to us at the best.

Black Dog PhytoMAX-2 1000 Watt LED Grow Light Fixture

Most powerful LED Grow Light

Back Dog LED is one of the most scientific and researched backed companies in the grow lighting industry, and they use this to produce the most powerful LED grow light on the market.

The PhytoMAX-2 features the largest heat sink in the industry, resulting in superior cooling and increased lifespan of the light. It also contains ultra-quiet and reliable fans to further control temperatures.

If you like the features of this light but don't need that much power, check out the other Black Dog LED models. The PhytoMAX-2 line ranges from 400 Watts - 1000 Watts.

Most Efficient LED Grow Lights

LED grow lights are incredibly efficient in general, but what is the most efficient LED grow light?

This was a tough choice as well, because smaller LED grow lights tend to run more efficiently than larger ones, so the playing field is not entirely level.

Even still, there is a newer LED light that operates at an INSANE efficiency, and once we thought it through was the obvious choice.

Gavita Pro 1700e Gen 2 LED Grow Light

Most Efficient LED Grow Light

Gavita took the industry by storm with their 1650e LED, and quickly made improvements upon it to come out with the Gavita Pro 1700e Gen 2 LED.

All of the lights on this list can be considered innovative to some degree, without a doubt. But, there is one LED that stands out as the most innovative of 2021 thus far.

Iluminar iLogic 8 630 Watt LED

Iluminar iLogic 8 630 Watt LED

The Iluminar iLogic 8 630 Watt LED Grow Light is easily one of the most innovative of the year - featuring a unique spectrum that we've yet to see on any other fixture that contains both UV and IR wavelengths. It covers a footprint of 4' x 4', and puts out a whopping 1800 µmol/s at a PAR Efficiency of up to 2.85 µmol/J.

Cutting-edge scientific research has revealed that plants can harness far-red radiation for photosynthesis when supplied in addition to full spectrum light.

Outdoors, plants have evolved to exploit a broader range of energy (incident solar radiation) than LEDs have historically been able to provide.

The iLogic™8 UV+FR builds on recent advances in LED technology to fill this gap, providing a quality of radiation that more closely mimics the Sun.

The iLogic™8 UV+FR moves growers beyond the paradigm of PAR and PPFD; its broadened spectrum represents a quantum leap forward for controlled environment agriculture.

The UV mitigates the risk of powdery mildew and pest infestations while simultaneously enhancing a broad range of quality metrics including terpenes and flavonoids.

A true win-win for indoor cultivators, the iLogic™8 UV+FR delivers the same high efficiency, light uniformity, and performance that growers have come to expect from ILUMINAR.

Best COB LED Grow Light

COB, or Chip On Board, is a newer technology that more and more LED grow lights are starting to employ.

California Lightworks SolarXtreme 1000 Full Spectrum 800w LED

Best COB LED Grow Light

The California Lightworks SolarXtreme 1000 is by far the best COB LED grow light currently on the market.

It comes in two options - with or without supplemental UVB light. If you are a serious grower, there is no reason not to add to your spectrum!

This grow light is super easy to use, and provides you with a full, balanced spectrum for all cycles of growing. It also features a new direct AC drive technology, eliminating the need for noisy, inefficient LED drivers.

The California Lightworks SolarXtreme pulls 800 watts from the wall, and only puts out 2550 BTU's of heat. For the power and size of this light, that is not very much!

This beast can fill a veg footprint of 8' x 8', or a flowering footprint of 5' x 5'. You can expect to pay around $34.56 per month to run this light. California Lightworks will appear in more than one instance on our list of the best LED grow lights.

Best Commercial LED Grow Light

The best commercial grow light will differ greatly from the best grow light for one plant. There is a lot that goes into commerial growing that hobby growers don't even think about, such as compliance, wet rating, etc.

But at the end of the day, a commercial grow light also needs to be super efficient, while producing HUGE yields - and there aren't many lights that check all these boxes.

Best LED Grow Light For One Plant

As we mentioned earlier, part of what makes an LED grow light the "best" for a given category is its size. So, it goes without saying that the Gavita Pro would not be the best LED grow light for one plant!

There are plenty of LED grow lights capable of growing just one plant, but generally, when growers focus on just one plant, they want it to be awesome.

They want it to grow huge, fill out with dense flowers, and be of the highest quality. So, the LED grow light used needs to be the best.

Covert LED-X 500 Watt Full-Spectrum LED Grow Light

Covert LED-X 500 Watt Full-Spectrum LED Grow Light

The Covert LED-X 500 Watt Full-Spectrum LED Grow Light is great for growing a single plant, but can also be used to start clones, vegging a few plants, or simply as supplemental lighting.

It pulls just 500 watts from the wall, and costs just around $20 a month to run it. If you're only growing one plant, this will be more than enough to grow a monster of a plant. It fills out a footprint of up to 6'x6'.

If you need to tune this down during the earlier stages of veg, you can dim it down to as low as 200 watts - saving you money and keeping your plant healthy and preventing light stress/heat stress.

From an output standpoint, you can expect to see about 1050 µmol s-1, with an efficiency of 2.1 µmol s-1 per watt. Four passively cooled LED bars provide great light coverage and keep heat low.

Just like the Covert 250 we discussed earlier, this can be paired with the Covert Lighting Controller for the ultimate automation and control over this fixture.
