What Are COB LEDs?

COB stands for chip-on-board and refers to how the LED chip is mounted onto the board and is the newest generation of LED technology and boasts some impressive stats.

For a start COBs have a much higher lumen per watt ratio than traditional HID lights, which means that you can get more light for less power consumption as well at using bulbs with an average lifespan up to 50 times longer!

The Differences Between COB LEDs And Traditional SMD LEDs

While both COB LEDs and traditional SMD (Surface Mounted Device) LEDs have a whole host of things in common, there are a few key differences.

COB LEDs are much more powerful than SMD LED lights and emit a wider spectrum of light, meaning that they offer the best performance for plant growth.

COBs also have better thermal properties which mean less power is required to cool them when in operation so you can get away with using smaller fans!

All this combined really helps plants grow that bit better!

Why Choose COB LED Grow Lights?

There are a number of reasons that many growers are switching to COB LEDs in their setups, we’ve listed a few below:

Light Intensity

COB LED’s produce the perfect intensity for plant growth. For example, as COBs emit a wider spectrum of light they are better at penetrating through and reaching those deep-rooted plants that would otherwise be shaded by traditional bulbs with limited spectrums.

Heat Output

COB LEDs produce an amazing light output without generating significant heat unlike say CFL grow lights. COBs produce less wasted electricity which equates in higher energy efficiency – saving you money with your power bills!

Conclusion

COB LEDs are the future of indoor plant growth and many growers have already made their switch. There is no need to search anymore, we’ve done all your research for you!
