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.
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:
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
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
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
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.

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
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.
It pulls just 65 watts from the wall, and you honestly won't notice it on your energy bill.
We estimate most growers will spend under $3 a month using this light!
It uses a super high-efficiency, high-intensity white light quantum board with a total of 120 pcs Samsung LED's, so you know you are getting a quality light.
While this is a smaller LED, it still puts out an impressive amount of light.
