FAQ

Q. What is a Quantum Board?

 

A. The Quantum board is a large circuit board with several LEDs mounted to it. The LEDs are then linked together in a series to create strings, and these strings are later joined in parallel configurations to make them compatible with normal high-powered constant current drivers.

Q. Which light spectrum should I choose from these three – 3000k, 4000k, and R-spec?

A. This solely depends on what kind of results you want for your plants. Different spectrums are great for different growing stages. The 3000k spectrum is ideal for all plant growth levels, i.e from seeding to harvest.

The 4000K spectrum is great for vegetation level only because it delivers a much higher blue light spectrum.

Last but not least, there is the R-spec variant that was created to replace the 3000k spectrum. Just ensure that you pick the right spectrum for your plants to get the best yields.

Q. What are the advantages of Quantum Board (QB) LED Grow Lights over Chip on Board (COB) Grow Lights?

A. Many people have been asking why they should select QBs over COBS. First of all, the QBs have easier thermal management than COBs. This is because the board can be installed to a small piece of aluminum without active cooling and the diodes remain cool.

Also, these boards are very efficient as they produce more than 180 lumens by using just 50 watts. This is unlike the COBs that produce around 160 to 170 lumens using the same 50 watts. Another advantage is that these boards produce a more evenly distributed light than the COBs.

Q. What is the difference between the Quantum Board and Chip on Board?

A. If you’re new to LED grow lights, differentiating between the Quantum Board LED grow lights and Chip on Board LED grow lights may be somehow challenging. These because they all feature hundreds of individual diodes mounted to a little board.

The main difference is that light diodes on COBs are tightly packed together unlike diodes on QBs which are spread much further from one another. Also, the idea of drawing the power of several small lights to deliver one powerful source of light is the same, but the Quantum Board lights do it on a bigger scale.

Conclusion

Picking the best quantum board LED grow light is important if you want to increase your grow yields. An efficient grow light will provide even coverage and deeper penetration for excellent growth.

In this review, we’ve conducted thorough research and included all the vital information that you need to select the most ideal quantum board LED grow light for your plants.

I hope you’ve found a grow light that not only meets your needs but as well as budget. If you’re a small grower, ensure that you pick a nice QB LED light that offers full-spectrum and covers your plants abundantly. For professional growers, pick the best LED grow light with great power.
