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

We have an entire post on choosing your grow light that can help you compare the different lighting technologies so you can arrive at the right conclusion.

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 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.

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.

It comes with a 1-year warranty and is by far the best LED for under $250.

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.

HLG 65 V2 LED Grow Light

HLG 65 V2 LED Grow Light

The HLG 65 V2 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.
