The Best LED Grow Lights 2020 0

Light-emitting diodes (LED) have been around for over 50 years, even though it may seem as if they are a new technology. 

This is because it has only been in recent years that the advantage of using LED light has been noticed by both professionals and enthusiast growers.

There are several reasons why LED grow lights are so popular. A big plus for LED's is that they are energy efficient. 

LED's are up to 75% more efficient than incandescent lighting, and last about 25 times longer.  That is a big plus!

Other advantages of LED light are that they:

  • Can stimulate growth in plants
  • They have adjustable wavelengths
  • They are energy efficient
  • They are compact in size
  • They are very durable and long-lasting

Things To Consider

When looking for a set of LED lights, it is best to get a set that is quality and will suit your needs. 

If you choose a set based solely on a lesser cost, you may end up with a product that costs you more in the long run. 

Time and effort and your original plants could be ruined if you don't have the right lights. 

It pays to research the types of lights available and what you need regarding your growing. Set your goals and educate yourself on what you need to get there. 

It is seldom a good idea to skimp on costs thinking that you will upgrade at a later date when you can afford it. 

If you don't set up your process correctly from the beginning, you may not have a later date to count on.

When looking for LED lights, consider the following important information:


You want your grow lights to be durable. It can be extremely frustrating to have to replace lights a short time after purchase, or in the middle of a grow cycle. 

A quality LED light should last about ten years. We may be biased, but we believe that a product manufactured in the United States according to high industry standards, is the place to start looking. 

Four of the five LED grow lights mentioned in this article are made in the United States.

Brand Name

When you start looking, you will find numerous brands and manufacturers on the market today. 

If you are looking at different lights that are comparable, check out the brand. 

As with most other items, go with a brand that has a good reputation. If you have any difficulties, you want a company that will stand behind its product and provide excellent customer service.

Energy Efficient

You will be expecting a lot from your grow lights. They will need to be functioning for at least ten to eleven hours each day. 

That is a big draw on the amount of energy you will be using. You want a product that will be easy on your electricity bill. 

Check how many units the light is in total output. Anything less than 300W will cost you. 

Choose something that is on the higher end of 600W to 800W or more. The higher output will compensate for any wattage loss.


Because the lights are in constant proximity to your plants, you want to make sure that the lights will not be damaging the plants by the heat that they emit. 

Another thing to consider is that lights that have a higher heat output will also burn out faster. 

Semiconductor Chip

An LED’s light core converts electricity to light and determines the wavelength of that light.

The chip needs to have at least 3W to be able to provide sufficient illumination.


What will you be growing? Certain LED lights are made to supply the needs of specific plants. It is not always a one-size-fits-all with LED lights. 

Depending on the plant, it will need different wavelengths during each growth stage. Tomatoes will require a different type of light than flowers. 

It is also essential to consider if you are doing just vegetative cycles or if you are doing flowering and growing processes too.


This is a significant factor. What is the size of the area you will be growing in? As a general rule, you will need 32 watts of actual power per square foot. 

Again, it depends on the plants that you are growing. Some plants take less light (like lettuce), and others take more (like tomatoes). 

You will need to determine the amount of light your crops will need.

Easy to Use

There may be times when you need to adjust the position of your LED lights. If you get a quality light, it will also be able to be adjusted with ease. 

Look for lights that have both wavelength and light intensity adjustments. Ease of maintenance is another an important factor. 

Full Spectrum

An LED is not just an LED when you want the light to simulate the photosynthesis process. The process requires different wavelengths, as we mentioned earlier. 

You will want an LED that can deliver the full spectrum needed throughout every stage of the growth process. 

Some plants need a light in the red and blue range along with the light being infrared and ultraviolet. A quality LED grow light will be able to provide these variations.


Last but not least, you are going to want a light that has a good warranty. Whatever light you choose should have a decent warranty and even free return shipping. 

A reputable manufacturer will stand behind its quality built product. 

In Conclusion

There are a variety of things to think about when looking at what LED grow light you should purchase. Use the above factors as a guideline when considering what you need.

If you purchase a quality product, it will cost you upfront, but inferior products always end up costing you more in the long run.

The Top 5 Fan-less LED Grow Lights 1


LED grow light technology is still new and rapidly evolving. While LEDs are much more efficient than traditional HPS/HID grow lights, they still output heat.

To manage this, most LEDs have built-in fans to move the heat away from the diodes and keep them from overheating and getting damaged. While this method of heat management works, it has a few drawbacks.

First, the fans themselves have a lifespan and can break or be damaged. Every additional component in your light is a potential point of failure. If the fan breaks then it has to be fixed or replaced if you want to continue using the light during your grow.

Fans also accumulate dust, dirt, and other buildup from your grow room. This means they have to be regularly cleaned in order to operate effectively. Many grow lights don’t account for this in their design and make it difficult or impossible to easily clean the fans. If you’re using one light then this is a minor issue, but if you’ve got more than this can be a huge pain.

Finally, while most fans are advertised as “silent”, many end up being pretty noisy, which can be annoying.

Many LED manufacturers are catching on to these issues and some of their latest designs have eliminated the need for fans entirely.

They do this in a few different ways such as adding much larger heat sinks, opting for newer hyper-efficient low heat output diodes, and increasing the overall surface area of the light to reduce areas of highly concentrated heat.

On top of not requiring a fan, these lights tend to have a lower overall heat output, run more efficiently, and have a longer lifespan compared to LEDs with internal fans. 

Here are some of the best options for fanless LED grow lights: 

1) Spectrum King SK402

Wattage: 460 Watt

The Top 5 Best COB LED Grow Lights for Every Grower 0

COB chip on diode LED

As a grower you're always on the lookout for the best and brightest when it comes to new grow light technology. A good source of light is the best investment you can make for big healthy plants and huge yields. That's why you should be looking at COB LED grow lights, they don’t only blow traditional HPS  bulbs out of the water, they’re also a big step up over standard LEDs.

COB (Chips on Board), is a new technology of LED packaging for LED light. Multiple LED chips are enclosed together as one lighting unit. When turned on, they look like a single light source instead of multiple individual lights. Slowly but surely, these COBs are taking the grow light market by storm.

The main advantages of COB LED grow lights over regular HID and standard LEDs are:

  • Improved electrical efficiency so you save energy and reduce power costs.
  • Highest usable lifespan of any grow light technology so you won't be replacing them any time soon.
