COB LED vs Quantum Board: Decoding The Battle Of Grow Lights

Today, the global population is fast exceeding the natural land’s ability to grow and produce food and plants. And, considering that land in itself is becoming more of a scarce commodity and people are only expanding, there has been a consistent need for everyone to produce more food. 

If we’re really going to get better at producing food, then it only means that our methods of production need to get better just as well. And, if that happens, it means we need to look at artificial production methods to see what benefits they might have for us. 

This is why both COB LEDs and quantum board lights have become especially popular. They provide a way for growers to essentially break free of the limitations of natural lighting methods, thus allowing us to artificially make the plants we need. In this article, we’ll look into the two options and how they might compare with each other. 

COB LED vs Quantum Board: Understanding the Different Lighting Technologies

What Is COB LED? 

Much has been said about “Chip-on-board” lighting technology. Known as “COB lighting” for short, this lighting variant is notable for one thing – its unique chip arrangement mechanism. You see, here, manufacturers arrange chips in a clustered format – instead of with other traditional LEDs where chips are arranged separately. With this format, you have different diodes in one unit, and this system provides a significant amount of uniqueness across the board. 

With the regular COB LED, you have different characteristics that make up its shape: 

  • A Sleek, Easily-Built Design: To begin with, COB LEDs are very compact. This is because instead of getting LED chips and placing them separately, you’re essentially combining them together into a single body. So, if you need a little more space for your grow lights, you can easily rely on COB LEDs
  • All Your Light In One Place: You should also remember the fact that COB LEDs essentially take all of your lights and concentrate them into one place. Considering that you need something that helps you grow plants, there is no way to overstate the importance of this benefit. 
  • Everyone Gets Light: The close packing of LED chips in COB LEDs also means that you can easily achieve uniformity when it comes to light distribution. Since you’ll need consistent lighting for your plant growth, we should also point out that this is very critical. 
  • Colors Are Mixed Better: The feature of enhanced color mixing means that you can use COB LEDs whether you want warm or cool colors in general. 
  • There’s Not Much Glare: Another interesting characteristic of COB LEDs is that they tend to significantly cut down on overall glare. This might mean little to growers, but it is worth pointing out anyway. 
  • Grow Whatever You Like: Of course, we should also note the fact that these lights make it possible to grow just about anything you’d like to. Because their color temperatures are so varied, you’re pretty much covered. 

A Look Into Quantum Board Lighting Technology 

Of course, before we go into the comparisons, it will help us to understand the other side of the spectrum a little bit more. And, this is why we have the quantum board lights. 

In a nutshell, a quantum board light is a lighting option that is actually built mostly to serve in growing plants. These lights are especially made to help improve the efficiency with which you can grow lights in internal environments, and they work with the “Quantum Board” design – essentially, a design scheme where you have an array of mid-power LEDs packed densely on a flat board. 

The lights in quantum board lights are specially designed to provide an enabling environment for plants to grow. And, for them to do that, they need to have several specific characteristics. A few of these include:

  • Seamless Energy Conversion: If you’re looking for a lighting option that converts energy into light easily, then quantum board lights are definitely among the top options. Now, you will need to incorporate high-quality LEDs into this mix, but these lights are known for being quite effective across the board.
  • Operating Across The Spectrum: You usually find these lights in full-spectrum LED mode. So, if you’re looking for any wavelength at all, there’s a considerable chance that a quantum board light will be able to achieve it easily. As you would imagine, this means that the lights help to support plants regardless of the stage of growth they are in. 
  • Supporting More Than One Board: We should also point out the modularity of the design of quantum board lights. Essentially, this means that you can add more boards to what you already have if you think that your existing setup doesn’t match up to your requirements. As you move into a larger space and change your plants, you can rest assured that these lights will be there for you. 
  • Control Your Own Brightness: At the same time, we should also note that quantum board lights make it possible for you to optimize dimmability as much as possible. If the light is too bright, then you can dim it and pretty much cut it. 
  • Use Them For Pretty Long: As you can imagine, longevity is another characteristic that you can enjoy with quantum board lights. This shouldn’t be surprising, especially since they are also LED lights too. 

Now, you need to remember that these characteristics will vary based on the brand and what they provide you. So, you might want to keep an eye out for that. 

COB LED vs Quantum Board: Comparing Their Light Intensity

Now, we’re into the thick of things – which of these lighting options is better, and what should you consider when you’re making a choice?

When you’re beginning on the comparison front, one of the first things you want to look at is which of the options provides a greater level of light intensity? At the end of the day, your plant will need impressive levels of light intensity if it really is to grow. So, which of these lighting options will be better for you? Here are a few things you might want to keep in mind: 

The Design Of The Light Fixtures

As we already pointed out, the design of COB LEDs incorporates the addition of different chips in a single place. The chips are mounted on one single substrate, and that design will affect the way the LED eventually distributes light. 

On the flip side, quantum board LEDs usually come with flat boards that are packed densely with entry-level LEDs. In terms of light distribution, uniformity is significantly higher with quantum board LEDs. 

How Many LEDs Do They Have? 

Next, we look at LED numbers. Generally, both LED options vary in this regard, with the total output depending on how many chips you have and how strong they are. Of course, this will depend on the manufacturer and model you’re working with as well. 

How Is Light Varied? 

The spectrum of light you’re working with will also play a considerable role here. Generally, different plants require different spectrums of light to work. And, if you’re working towards planting a specific type of plant, you will need to make sure that your light option has the right spectrum range. 

Both options are generally designed to operate with a full light spectrum. And, considering that this range also includes the wavelengths needed for photosynthesis, you can imagine that they are even more ideal for planting. 

Consistency In Generating Light 

When it comes to uniformity in light distribution, we would generally pip quantum board lights to take the prize here. With their flat, densely-packed design, these lights provide higher levels of uniformity over the area you need to cover. COB LEDs are highly ranked in this area as well, but you generally run the risk of distributing light more towards the center.

How Far Do They Cover? 

Next, we need to look into the coverage area. For quantum board lights, you get light options that are designed to specifically and effectively cover a specific area. On the flip side, COB LEDs tend to operate in different configurations, and their coverage isn’t the same. 

Can You Control Brightness? 

Finally, let’s look into the dimming capabilities of the lighting options. Both options generally offer dimming functionalities, so they are pretty even on this front. If you find that your light option is too bright, you can just dim it and cut its intensity. 

COB LED vs Quantum Board: Which Has Higher Spectrum and Light Quality? 

It’s one thing for a lighting option to be bright, and it’s another completely different thing for it to be of a higher quality. With COB LEDs and quantum board LEDs, it’s important to have a good handle on lighting quality and the spectrum of light you’re working with. So, how do they really compare here?  

How COB LEDs Perform 

What Spectrum Options Are Available? 

In general, COB LEDs are designed to be customizable in their spectrum range. You can choose different LED chip types based on the wavelength you’re looking to achieve, and this means that you’re pretty free to personalize as much as you want. So, flexibility is a pretty considerable benefit here. 

The High Color Rendering Index

Another notable feature of COB LEDs is the fact that their color rendering index (CRI) is pretty high. Since your plants will need light that closely mimics the sun, you shouldn’t have much of an issue in this regard when it comes to the functionality you get from COB LEDs.

You’re Free To Personalize  

You should also note that you can customize your COB LED setup as much as possible. This way, you can include different levels of red and blue wavelengths, as well as other wavelength options that you want based on your plant’s needs and their growth requirements. 

The Case For Quantum Board LEDs

The Spectrum Is Consistent 

Generally, the design of a quantum board LED allows them to achieve more uniform spectrums as you move from one end of the board to the other. Experts believe that this improves light distribution and bolsters the coverage of the light option generally. 

You Can Get Full Spectrum 

In many cases, quantum board LEDs also come with full spectrums that allow them to work like natural lighting. It’s almost literally like you have the sun itself warming your plants.  Plus, wavelengths are balanced here, so you don’t have much to worry about. 

The Spectrums Are Efficient, Too

Now, besides just having a broad spectrum range, we should also note that the spectrums available in quantum board LEDs are of the highest efficiency levels. Because of this, you can easily ensure that much of the light you get falls into the right photosynthetically active radiation (PAR) range.

COB LED vs Quantum Board: How Energy-Efficient Are They?

Regardless of what  you’re looking to achieve, as long as lighting is involved, energy efficiency is one metric you should always have your eye on. With an energy-efficient lighting option, you’re able to do so much – including save yourself a lot of money and still get the most out of your lighting in general. 

Since we’re looking into a comparison between COB LEDs and quantum board LEDs, let’s also consider how energy-efficient the two of them really are 

Where COB LEDs Shine 

The Chips Are The Magic

As far as the energy efficiency of COB LEDs is concerned, you really need to focus on the fundamental chips that make the entire lighting possible. Their luminous efficiency is impressive, and this means that they have a higher light output per power consumer. 

You’re Not Confirmed 

The design of COB LEDs also allows you to be more flexible when designing how many LED chips you want – as well as the type of chips, in fact. So, if you think that a specific design allows you to optimize energy efficiency, you’re more than free to try it out. 

They Don’t Get Hot

When there is light, there is heat. But, the goal should be to cut down on the generation of this heat as much as possible. This is one area where COB LEDs also do quite well. With their efficient heat dissipation, these LEDs can give you more functionality while still lasting as long as possible. 

What About Quantum Board LEDs?

The LED Structure

As we said earlier, the LEDs used in quantum board lighting are mid-powered LEDs. They are quite efficient, though – despite what their name says. And, they do a pretty good job of finding that sweet spot between light performance and power consumption. 

Light Distribution Is Consistent

Like COB LEDs, you get a considerable amount of uniformity in light distribution when it comes to quantum board LEDs. Since the LEDs are packed closely, they distribute light everywhere , ensuring that your plants are properly soaked. 

Credit To The Design

Of course, we should also point out that the very design of quantum board LEDs is done with efficiency as the goal. They don’t take in much power, and they still light up the entire room. 

COB LED vs Quantum Board: Important Cost Considerations

Finally, you also need to have consideration for your budget and how much you will end up spending on these lights. Planting indoors can be a cost-intensive process, and as much as possible, you want to make sure that your cost profile is cut. 

It is important to remember that the cheaper option might not necessarily be the best for you. However, if you’re really curious about which is more expensive, here is how both options stack up: 

How Much Do You Have To Pay?

In terms of upfront cost, quantum boards actually tend to be more affordable. This is especially great since they’re newer, and as we’ve already pointed out, they tend to be better for some specific planting operations. 

That said, much of this will depend on the type of light you’re getting and the manufacturer’s pricing policy. So, feel free to shop around to get the best quotes and rates. 

Paying For Upgrades

Next, you also need to consider the fact that your light might not necessarily fit your requirements from the start. If you need to customize or modulate the light, then you will need to throw in a few extra bucks. 

Generally, customizing COB LEDs also tends to be more expensive than modulating a quantum board LED. But, at the end of the day, the goal remains the same – making tweaks to your setup to ensure that it meets your specific needs. 

You Might Need A Driver

Generally, lighting drivers help to improve the overall efficiency of your lighting option. And, if you really care about brightness and lighting efficiency, then you should get one. 

Interestingly, drivers for quantum board lights actually tend to be costlier than those of COB LEDs 

Remember To Handle Heat

Finally, you have to ensure that your lighting option is able to take out any pesky heating issues. COB LEDs generally do well to dissipate heat on their own, but quantum board LEDs might need additional tooling to do this. So, you would need to factor that cost in. 


At the end of the day, artificial light is becoming the new in-thing when it comes to growing plants. And, both COB LEDs and quantum boards are standing at the forefront of this industry. As a manufacturer, choosing which is perfect for you requires a significant amount of consideration.
