As a fellow indoor grower, I’m sure you’ll agree with me there’s some kind of a satisfaction when choosing the most efficient and best grow lights out there.

Perhaps you’ve heard the fuss about the best cob LED grow light, and now you too want to start growing indoors.

Here’s the thing.

Somehow, we feel like those past and most commonly purchased grow lights are old-school and are not giving results that much.

Yes, they are perhaps not sufficient enough particularly for those who are trying to get an incredibly amount of yields and believe that only the most recent and latest technology would be able to suffice their highest expectations.

But, my friend, you must fret not because from this moment onwards, I swear that your dilemma will be solved.

Look no further because I’ve got a treat for you.

I’ll show you on why the Chip-on-Board Technology is superior among all the grow lights out there and how they provide essential development for indoor growing.

In addition I must also mention on why they are being quickly deployed into various indoor grow rooms across the world:

  • Its most notable design advantage
  • Its simplicity
  • Its electrical efficiency and improved lifespan
  • Improved spectrum
  • Improved Thermal Performance
  • Conveniences

Those are just some previews of how great COB LED grow lights are.

Now, before we even start to talk about some best cob led grow lights, let’s see what they are exactly…

What Really is This COB LED Grow Light?

Well, all we know is that COB stands for Chip-On-Board. It is an LED packaging latest advancement that shows mounting of multiple Light Emitting Diode Chips directly into a surface of a particular material in order for these chips to form a single module.

In other words, a miniscule wired, that is packed altogether into a piece of ceramic or copper board so that they exist as a sole light source.

It’s like this.

When a COB LED grow light is energized, it would appear more like of a lighting “panel” than multiple single lights just like on the other case of particular LED grow lights. For instance an SMD LEDs mounted altogether.

Yup, it’s most probably true.

While there are still various applications on utilizing HID bulbs, the benefits of using COB grow lights just outweighs its disadvantages.

But obviously, the question will always still occur.

Does this latest advancement justify the cost?

As we all know, all these things that are new in the market will literally get your wallet close to zero.

But since COB grow lights are proven just beforehand, what it gives you is nothing but advantages particularly in the long term use.

Here are some of those advantages that COB grow lights offer compared to those grow lights that precedes before our very own COB LEDs.

  • Improved Electrical Efficiency
  • Improved Lifespan
  • Improved Spectrum
  • Improved Light Quality
  • Permits replacement of HID bulbs without any loss of light intensity
  • Better Light Distribution
  • Superior Thermal Efficiency

Quite a lot if I must say.

COB grow lights have given us the highest usable lifespan that a grow light can offer due to its very modern technology structure and design.

Even if the first capital is obviously higher, what we really want to know is that a quality LED fixture will certainly last for about 30,000 hours.

In other words, it will pay itself off in the long run, implying that its quality is just superb.

In addition, one of the primary reasons that COB grow lights have made their way so fast in the market is that their HIGH Color Rendering index is normally over 80 and it possesses broad spectrum.

If you want to know, CRI tells how the color of a light source alters how an object appears to an individual’s eyes and how well fine variations in color are illustrated.

Meaning, the higher the CRI, the more realistic will things look.

We might also want to know that up until now LED grow lights were the most picked for those individuals who are in need of low power.

As of right now COB LEDs are more efficient at generating photons than any grow light technology. In other words, at the same power consumption, COB grow lights will always outweigh other grow light technologies at giving us high quality light for our canopy.

For the matter of light distribution, certainly HID grow lights and COBs are both single-focused light sources.

But because COB grow lights are relatively easy to utilize and position, we could say that we have an extremely different instance here.

Rather than using one single light root, COBs can be spaced for an ideal uniformity to preclude any hotspots or low intensity areas in your grow area.

With that said please take a look at the table below on where I’ve tried to compare my previous experiences on various lights that I’ve used in the past.

But before that, please take note that I got all these data by getting the average performance of the said type of grow lights since obviously it would take a book to write specific information of every certain kind of grow light, that’s why I’ve made this comparison based only on the “average” stuff of a particular grow light.

As you can see, without any kind of biases or business matters, in total my favor goes to COB LED grow lights.


Because that’s what my experience on using this grow light tells me. I’m telling genuine facts here.

Well, you can purchase one on your own to see whether I’m telling the truth or not.

But before introducing you to my Top 10 COB LED grow lights, I might want to clarify the misunderstanding here.

I’m certain that you’ve now noticed that I am suffixing COB grow lights with LED (i.e. COB “LED” grow light).


Here’s the reason.

COB vs LED Grow Light

For all you know, there are no actual definite discrepancies between the two because “COBs” are merely a product of LED grow lights.

Meaning, they are one of the latest technology that the LED grow light products offer.

So the next time you encounter stuff such as comparison between the two in the internet, don’t be confused.

Let’s put it this way; COBs are the children of LED grow lights.

Yep that’s a more fun way and interesting analogy to get rid of your confusion.

Now, let’s go on to my TOP 7 list of my all-time favorite COB LED grow lights if ever you are thinking of getting yourself one.

Well, I highly suggest you to get one for the better and optimal yields. And take note, the following COB grow lights are the best COB LED 2019, so what are you waiting for?

Without further ado, here they are:
