When you walk in the grow lights industry, you come to see that initially, the COBs were ruling the light industry. Afterward, the quantum boards took the lead. If you want answers to some of your queries regarding quantum boards and COBs? There are several brands of COBs and quantum lights. You just have to check the price and performance of your interested brand. Let us start the comparison for COB Vs Quantum Board.
Quantum Board
Quantum Board LED Grow Light is a large circuit board that has hundreds of mid-power LEDs mounted to it. The LEDs are connected together in series to form strings, and these strings are then combined in parallel configurations to make them compatible with common high-powered constant current drivers.
A quantum board LED is a newer alternative to the more expensive COB grow lights. The quantum board is a large circuit board in which a string of LEDs are connected forming “intelligent spectrum string” resulting in a broader spectrum and bigger plants. True full spectrum is the result. Actually, a full spectrum LED grow light are best for plants growth!
COB LED Grow lights
A COB is known as the Chip on Board appears to the scene when thousands of lumens are required from a single source. A COB led array involves multiple chips mounted on a single common board made up of sapphire or silicon carbide as compared to the multiple chip configuration. COB technology mounts several thousand LED chips within a single metal or ceramic-based board. This innovation allows you to have greater packaging densities of the LED array. Some other advantages of COB lights include low energy consumption, constant uniform light output, and minimal footprints. The COB lights arrangement comprises two contacts and only one circuit.
Key differences between Quantum Board Lights and COB lights:
As both COBs and quantum boards use LEDs but they both vary in the white color spectrum scale. Some other differences are as follows:
Area coverage
The main thing that distinguishes between a COB and a quantum board is the area covered by these lights. A COB light has a single source of light, hence the light does not reach the outside area completely as compared to the middle section. On the other hand, a quantum board comprises diodes that cover the complete area uniformly. It does not cover the center part only. Quantum boards have more light spread, while the COBs only provide the central light spread.
Penetration Power
This difference comes out from the first one. As COB has strong light emission, it penetrates deeply below the canopy, especially in the middle part. The light penetrates slowly as it moves towards the outer part. Quantum board lights also have great penetration power but this is not as good as the COBs.
Heat Management
The main difference that comes for COB Vs Quantum Board is heat management. In the case of COBs, the small diodes, mounted on a small board, emit a great amount of heat. Single COBs are cooled down by heat sinks, however, multiple COBs use fans. On the contrary, a single aluminum board is used to cool down the quantum board led grow light. These lights emit the same amount of heat as COBs, but the individual diodes are kept safe from overheating through passive cooling and a heat sink.

Should I Get A COB Or A Quantum Board?
Either light works great to grow marijuana or any other type of plant, so you can’t go wrong whichever way you decide to go. But for most people, one type will be more advantageous than the other. Your decision will come down to a few key factors.
Advantages of Quantum Board Light over COB light
There have been several questions on which type of light one should opt to.
According to the statistics available, many are advised to go for Quantum Board lights over COB LED grow lights.
The main reason why many people prefer Quantum lights in indoor gardening is that they provide more even light distribution and require less vertical distance from the canopy.
Here is a list of advantages of using Quantum Board lights over COB lights:
Thermal management is so simple as compared to COB lights by putting a thin piece of aluminum with no active cooling making the diodes be in place and in excellent condition.
Quantum Board light will enable you to achieve light uniformity, unlike COB lights that will blasts their lights all over.
Looking for a light type that will consume less energy? Quantum Board light will averagely consume 50 watts for 180+ lumens, while COBs will do 50 watts for 160 to 170 lumens.
Did you know human beings can directly observe Quantum Board lights without being susceptible to health hazards? This, again, one of the significant advantages of using Quantum Board lights.
Disadvantages of Quantum Board Lights
Using Quantum Board light does not guarantee 100% efficiency.
You are likely to experience some disadvantages, just like other commodities.
Here are some of the demerits of using Quantum Board lights:
You will experience more difficulty if you are to build the boards yourself. This operation is smoother in COBs.
With the current only one supplier of Quantum Board lights, they are often out of stock.
With the uniformity of light in Quantum Board lights, some areas receive low light intensity.
With the mass production of COBs, they have relatively dropped in price as compared to Quantum Board lights.
Do you want to specialize in Indoor Gardening?
Are you want to find a best LED grow light? Are you in the process of trying to launch indoor gardening? Or are you disappointed with the previous results of indoor gardening?
To make it short and straight to the point, the best advisable option to opt to is Quantum Board lights.
You also need to know that the best quality yields need capital. Quantum Board lights are quite expensive as compared to their rivals in the market, such as COB light.
With its immediate competitor-COB lights, many are usually confused on which one to choose. COB lights are always cheap, small, and straightforward in structure. COB lights are massively produced since they have many producers hence leading to a massive fall in terms of their prices.
