Chip-On-Board LED grow lights are a type of LED light where the integrated circuits are built directly onto the circuit board.
This allows for more LEDs to be accommodated, making these lights more compact, lighter, and less expensive.
4 Advantages of COB LEDs
- Since more LEDs can be accommodated in the same sized circuit board, the device emits more light in less space. This makes COB LEDs compact.
- They’re also lightweight.
- They’re high-powered with strong light intensity and PAR values.
- However, they’re less costly than their surface-mounted counterparts.

COB LED Grow Lights: Final Thoughts
COB stands for Chip-On-Board, a technology in which the LED lights are mounted directly on the circuit board. This leads to better space efficiency than conventional surface-mounted LEDs.
This leads to compact light systems that occupy less space and output a huge amount of powerful light.
COB LEDs offer several advantages over traditional LED lights:
- Space-efficiency
- Powerful output.
- Better intensity and concentration
- More lightweight
- Less expensive
COB LED lights aren’t as common as surface-mounted LEDs, so there aren’t a lot of COB lights on the market.
As COB systems have lights packed densely, they need effective heat dissipation systems to run at reasonable temperatures, and effective reflectors also increase both the efficiency and concentration of the lights.
