Most conventional LED grows lights don’t produce enough lumen and PAR to effectively help your plants grow.
You need the best Cob LED Grow Light to improve lumen density, greater focused light, and lower heat. Apart from giving your plants a more uniform spectrum, Cob beads help focus the energy on the canopy to improve penetration and expedite the growth cycle.
The choice of Cob LED grow light, however, is huge on the market, and not every indoor grower knows what to look for.
What Is COB LED Grow Light?
Chip-On-Board widely known as COB is a latest technology used for LED Packaging in LED Light Engine. Yeah, in COB lights multiple LED chips are packaged together as a single module. Yeah, it’s part of electronic packaging and It generates intense light because of multiplied potential of multiple LEDs.
What Makes COB LEDs Better?
Before we get to the reviews, let’s take a look at why COB LED chips are better. I’ll keep this brief, since you’ve probably already done the research on this, or you would not have found yourself on this page. This article has more info.
The advantages of chip-on-board LEDs are:
Compactness: far more LEDs fit into a much smaller space, meaning more output from a smaller area
High-Intensity: since more LEDs are packed into a smaller space, the light is more intense, meaning deeper canopy penetration
Design simplicity: only use 1 circuit with 2 contacts to energize all the chips on the COB array, reducing the number of components needed
Lower failure rate: due to lower heat generation and better heat dissipation and fewer welding points (since each chip is mounted directly on the substrate, instead of soldered in place), quality COBs have a lower failure rate
The primary disadvantage is the fact that COB LEDs are not yet available in every color spectrum. Luckily, they are available in the colors best suited for growing plants (white and pink). The first 4 lights below use warm white and cool white COBs, while the final fixture uses pink ones.

Things to Consider When Looking for Cob LED Grow Lights
Here are the most important factors to take into consideration:
Rich Full Spectrum
What makes Cob LED grow lights special is their ability to deliver a super bright full-spectrum and high PAR output. So, make sure the lamp contains all lights your plants need to thrive in each growth stage. Choose full spectrum led grow lights with the Veg and Bloom modes and each mode should have the appropriate wavelengths.
Efficient Heat Dissipation
You can choose a fixture with an integrated cooling system (made up of high-speed cooling fans and heavy-duty heat sinks). Alternatively, you can consider a model with an independent cooling system. Regardless of what you choose, make sure the lamp can efficiently dissipate heat.
Final Thoughts
For this roundup, the winner is ECO Farm Cob LED Grow Light. What makes this light stand out is the third-generation full-spectrum Cob beads. The fixture is extremely bright and the PAR output is exceptionally high. So, you should expect it to do a great job of expediting the growth cycle. It is also very effective at dissipating heat and maintaining optimal temperatures.
