One of the main benefits of growing plants inside is the amount of control you can exercise over the growing conditions of your crop. By carefully controlling temperature, moisture, and, as we’ll focus on in this article, light, you can ensure great growth and excellent yields for whatever kind of plant you’re growing.

The best LED grow lights enable you to precisely control the amount and the wavelength of the light your plants are getting. This means that you can dial in certain types of light while your plants are young, and then switch to another wavelength once they start to flower. Whether you’re growing some flowers in pots or setting a hydroponic system, you can benefit from adding a grow light to your setup.

In this article, we’re going to take a look at 6 of the best LED grow lights you can buy online. There are great options to support a number of different growing projects!

Let’s get started!

Key Takeaways

After searching the internet for great products to help indoor growers get their plants the light they need, I settled on the RDJ Bouns 720W LED Grow Light as the overall best LED grow lights. It’s a simple and no-frills product that can help growers provide the ideal lighting conditions for a large 4-foot-by-4-foot growing area. And, since many home growers are looking for lights that provide great value and cover a lot of ground, it will be an excellent choice for a lot of people.

However, if you’re looking for a smaller lamp, I’ve also included a couple different options like the GooingTop LED Grow Light and the KEELIXIN Grow Lights for Indoor Plants.

Buying Considerations for The Best LED Grow Lights


When considering LED grow lights, your first priority should be checking out the total PPFD (photosynthetic photon flux density) that each of them can produce. PPFD indicates the total usable light that a grow light delivers per square meter, which means that it tells you how well a grow light can effectively support photosynthesis.

If you’re all about performance, then you should opt for a higher PPFD, but for other growing projects you might want to consider plant-specific needs. In many cases, a lamp that offers a lower PPFD but more efficient energy usage might be preferable.

Wattage and Average PPE

Another crucial factor for indoor gardeners when selecting a grow light is the wattage and efficiency of the system. Wattage is the amount of energy required for the grow light’s operation, and PPE (photosynthetic photon efficiency) gauges how effectively it converts that electrical energy into light.

Choosing a lamp that offers superior PPE to an alternative ensures cost-effective and efficient operation. However, it’s essential to strike a balance, as the highest PPE option may not provide sufficient PPFD to support the growth of your plants. Finding the optimal combination of adequate PPFD and high PPE is key to getting the best LED grow lights for your needs.


Lastly, whether or not you need a grow light that has lots of adjustability is a crucial factor to consider. Going for an adjustable grow light enables you to modify the emitted light’s wavelength and can help you create optimal conditions for plants at various growth stages.

Young plants benefit from more blue light (400–500 nm) while they’re getting established in soil or a hydroponic setup, whereas plants require abundant red light (620–780 nm) during the flowering stage. Although this adaptability can ensure tailored conditions for your plants, some gardeners will prefer a grow lamp that puts out light in the middle range and will always be appropriate.

How I Choose These Products

I definitely understand that grow lights represent a significant investment for many home gardeners—I just have to look at some of my own credit card statements. That’s why I worked hard to find products that are high-quality and reliable. It’s crucial that products like these not only support your gardening projects, but also do so for a long time.

As a result, I focused on recommending the best LED grow lights for plants from brands that you can trust. To do so, I relied on my own experiences but also reached out to some of my coworkers here at Gardening Product Reviews, who have also written about grow light technology.

Final Verdict

Overall, I rated the RDJ Bouns 720W LED Grow Light as the best LED grow lights you can buy online. They have the power and size necessary to make a big impact on any indoor grower’s setup, whether hydroponic or conventional. Although its power and price might be a bit too much for some gardeners, this list luckily contained lots of other options. I hope you found something that works for you!


Which LED light is best for plant growth?

There isn’t any one product that I’d be comfortable calling the best LED grow light for plants full stop. Exactly which product is best for supporting plant growth depends on a variety of factors, such as the types of plants you’re planning to grow and how large your growing environment is. In general, it’s best to go for an adjustable LED grow light that can pump out enough light to cover your entire growing area.

What LEDs do commercial growers use?

Commercial growers use LED grow lights that are based on the same technology that home growers use. They are usually full-spectrum and tend to be highly energy-efficient, since commercial growers are sensitive to costs.
