Best LED Grow Lights Of 2024


Quick Navigation

When you have decided to upgrade 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. It's hard to find good brands and models among the many cheap and low-quality options available.

And with the price of some of these grow lights, it's crucial that you do your research before purchasing. Lucky for you, we have curated a list of our top picks for various applications.

Before you buy an LED, you should make sure it's the right light for your indoor garden.

Before we get started with our list of the best LED grow lights, we will cover some basics of this technology.

What Are LED Grow Lights?

LED stands for light-emitting diodes. LED grow lights have recently come down in price. This has allowed home growers everywhere to make the switch to using them as their lighting option.

These lighting systems produce low heat, come ready to plug and play, and 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 many different forms. Let’s look at each type so you can find the right LED light for you:

Multi-Rail/Bar Fixtures

Multi-rail, also known as multi-bar fixtures are the newest and greatest fixture type for many reasons. These are the main types of fixtures you will see on the market nowadays.

Their larger form factor means better PAR distribution/uniformity and higher coverage. These fixtures have spaces between each set of light bars. This allows them to disperse heat passively without the need for fans. This makes them more reliable.

Another benefit of the multi-bar design is better airflow through the canopy. Since there is no full panel that blocks the airflow from circulation or exhaust fans in your room.

These features among others make them the best option for grow tents, grow rooms, commercial applications, vertical growing, and greenhouses.

Another benefit to this type is many of them are built on a folding platform, making shipping less expensive and safer! Below you will see why many of our favorite LEDs feature the new multi-bar designs.

LED Grow Light Panels

Panels were once the most common type of LED grow light. However, recently they have been overtaken by the multi-bar fixtures mentioned above.

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, these often come to mind. However, these heavy fixtures are being replaced by their lighter multi-rail counterpoints that have many more benefits to growers.

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).

Besides being used as supplemental lighting, many growers use specific low-wattage clone LED bars to start seedlings and for cloning.

Grow Light LED 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 bulbs. This will give you all the added benefits of LED grow lights.


What Makes The Best LED Grow Lights For Plants?

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

Grow Light Coverage/Footprint

The footprint is an important factor when selecting a grow light for plants. You want to fill your growing space with plenty of light maximizing your growth potential.

PAR, PPF, and PPFD

The best full-spectrum LED grow lights will show their PAR, PPF, and PPFD specifications. These will help you determine the performance of a grow light ro choose the right one for your application.

This topic can be overwhelming for new growers, and many dont need to dive deep into it. For those with a strive for knowledge, we have a helpful blog category for all things grow light education.

Spectrum/uniformity

The best LED grow lights have an even spectrum. This way, if you have 4 plants under your light, they all get the same spectrum.

Most LEDs now use white LED diodes, but they still include other colors not easily noticed by the human eye.

It is important to mention that the best spectrum consists of not just white light. They also include red light, blue light, infrared (IR), and Ultra-violet (UV).

Full spectrum LED grow lights allow you to grow from seed to harvest with the same light.

Efficiency

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.

Power

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

Reliability/Durability

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.

That isn't an issue with the Gavita CT. It's designed to perfectly replace any HPS fixture you currently have in your facility or grow room.

If you're concerned about switching because you think your HPS is more powerful, think again. This fixture puts out an impressive 1930 µmol/s output of optimized lighting at up to 20% energy savings vs. 1000 W DE HPS fixtures. It does this with an insane efficiency of 2.47 µmol/J PAR rating.

With a wide, even light distribution, you still get the HPS light throw you're used to - but with improved coverage, so less light gets wasted.

Why Trust What We Have To Say?

We have been in the business for a long time, and have learned a ton about it during our growth. Hydrobuilder Holdings is a leading omni-channel retailer of specialty agriculture and hydroponics equipment and supplies.

Hydrobuilder Holdings was initially formed through the acquisitions of Hydrobuilder.com, GreenCoast Hydroponics, Elevated Equipment Supply, Way to Grow, Home Grown Ventures (HGV) Nutrients, and New England Hydroponics.

Together, the six businesses create a leading omnichannel retailer of specialty agriculture and hydroponics equipment and supplies with over 200 employees.

Our acquired businesses have been operating for approximately 85 combined years and are integrated through an omnichannel model, which includes a large retail and distribution network and a scalable eCommerce platform, providing us with a unique competitive advantage.

This experience has brought us a wealth of knowledge about grow lights, and specifically LED grow lights which continue to be by far our top-selling type of grow light we offer.

Our industry experts are also growers themselves, so we not only know what our customer experiences have been, but we have our own as well that we factor into this list.

LED Grow Light FAQ’s

Can I use any blue and red LED light to grow plants?

There is no exact spectrum that plants need to grow. Rather, plants prefer a ratio of various colors, including red, blue, white, IR, UV, etc. that help provide a plant with energy to increase growth rates, overall plant health, and the rate of photosynthesis.

Any grow light on this list, and others on our website were designed specifically to grow plants, so make sure to choose a brand we sell to be sure you are getting a quality product with a proper spectrum for growing plants.

How much does it cost to run an LED grow light?

The cost it takes to run a grow light depends on the wattage of the light and your average kilowatt-hour in your state. This can vary greatly depending on what state you live in. Below is a basic example of the equation.

We use the 12-hour light on time during flower for the equation since your plants will be in flower longer than in veg.

How we estimate energy costs

The displayed energy cost per month was calculated at the national average of $0.17 per kW/hr used.

Total watts * how many hours 'on' per day / 1,000 to get the total kW hours in the 'on' period

Total kW hours in period * cost of kW hr * days in month = $TOTAL MONTHLY COST

3x3 Grow Tent Package Example:

600 watts * 12 hours on / 1,000 = 7.2

7.2 * $.17 per kW/hr * 30 days per month = $36.72
