What are COB Grow Lights and How They Compare to Traditional LEDs

Postato da [[autore]] su [[data]]

LED lighting has itself only recently become a standard in the community, thanks to lower prices and their longevity. LEDs mimic natural light and provide a full, balanced spectrum of red, blue and green. They are composed of light-emitting diodes, their design features help make them more energy-efficient and longer-lasting, and often they are equipped with cooling systems, which improve brightness and longevity by keeping temperatures low.

A new technology for LED grow lights is stepping forward, increasing in popularity, and may soon become the industry standard. This technology is called COB, or “chips on board.” Let’s go ahead and take the time to learn a little more about it.

What Are COB LEDs?

The biggest difference between COB LEDs and regular LED panels is the architecture: COBs are wired and packaged into a single module so that they function as a single lighting source. By bonding the chips directly into the circuit board, extraneous components are avoided to maximize the LEDs potential.


A COB light incorporates a multitude of minuscule LED chips in one board, making them appear as a sole source of light. The chips are about the size of a quarter, allowing for much denser packing. The lights are usually housed in ceramic, copper or aluminum, creating a kind of “heat sink” for more efficient heat management.


The lack of extra materials decreases the heat generation produced by the LED chips, increasing the efficiency rate of the unit. COB units do not have as many welding points as traditional LEDs, and also do not use lenses. In essence, it is a simpler system that promises better efficiency rates due to the lack of additional parts.

Advantages of COB Technology

COB LEDs hold significant benefits for indoor growers, as the concentrated chips produce an intense white light, which is beneficial for plant development. Studies have shown that COBs offer a high Color Rendering Index, which is associated with a better quality of light.

In addition, the design of COBs is such that allows for much more compact units. This makes them an excellent choice for growers with limited space. Plus, the units run at relatively low temperatures, eliminating the need for extra ventilation.

Also, with a COB Grow light, you’re converting separate diodes into a single light source, which can be more energy efficient because they use up the wattage more efficiently, offering better light coverage and bigger PAR values. This way you can take full advantage of the LEDs powerful spectrum and let your crops reach their most bountiful yields.

Should You Make the Switch?

COBs are a great way to decrease temperatures, increase efficiency and gain space, all of which are significant issues in indoor growing. In our shop, you can find a wide selection of COB grow panels to choose from.
