People jump on trends and get pretty obsessed. And few things are as trendy in the cannabis growing community as quantum board LED grow lights.

But what are they exactly? And perhaps more importantly, are they as good as they say? And if they are, which brand is best?

We’ll tackle all those questions and more. By the time you get to the bottom of this page, you will know everything you need to know about quantum boards, and you’ll know whether they are right for you and exactly which one(s) you should get.

Benefits of Quantum Board LED Grow Lights Over LEDs

Quantum Boards LED grow lights are the favorite of many people among all the types of grow lights available.

That’s because of the many benefits that they bring along. We have sampled some of the most significant ones below.

Simple Heat Management
Heat management has always been a concern with many grow lights. Some grow lights emit a lot of heat and end up causing leaf burn.

You do not have to worry about any of that while using quantum boards. Quantum boards distribute heat over the board to ensure there isn’t too much heat on one spot. Also, an aluminum heat sink is easily mountable on the quantum board to ensure it stays cool.

Even Light Distribution
Quantum boards help to spread light over the grow room evenly.

Some lights will cause blind spots, or have most of the illumination concentrated on one spot. Quantum boards evenly distribute illumination, which means efficient energy use. Too much illumination can also cause leaf burn. The even distribution of light by quantum boards ensures you never have to deal with such cases. Also, it ensures the crops get just the right amount illumination an ensures they are healthy. Furthermore, quantum boards rarely have blinds spots.

All the light is evenly distributed over the coverage area of the grow light.


The Samsung diodes (and the cheaper alternatives many brands use) emit a full spectrum white light that contains every visible wavelength of light. They are available in several different color temperatures, but all are close to natural sunlight. This makes it an excellent spectrum for plants.

While blue and red LEDs were common in the past, the industry is coming to realize that white LEDs are better for plants, so more and more manufacturers are switching to white. This switch began with HLG and their quantum boards.

These days, quantum boards often have additional diodes mixed in among the white ones, most notably deep red and sometimes UV and IR.

All growers know that full spectrum LED grow light is best recommended for plant growth.

High Efficiency
Quantum boards are highly effective as compared to the other types of LED lights. At a power draw of 50 watts, a quantum board will be delivering over 180 lumens for every watt.

That is quite impressive as compared to what the other LED grow lights offer. That means that these lights will be consuming significantly less energy, and hence lowering your power bills.

As compared to the other types of LED grow lights, quantum boards are easier to make and are hence cheaper.

Setting up a grow tent and buying all the equipment can be quite expensive. Any equipment that will do the work and is pocket-friendly is always welcome. There are many other reasons why you should opt for quantum boards if you are seeking an appropriate grow light. The benefits we have highlighted above should be reasons enough for you to go for quantum boards. Quantum boards are not without some misgivings, though.

We’ll explore them in the sections below and find out whether they are significant enough to make you shy away from quantum boards.

Disadvantages Of Quantum Boards

There are no major disadvantages of quantum board lights, when compared to other types of LED grow lights, but there are a few minor ones.

Canopy Penetration

White light penetrates better into the canopy due to the presence of green wavelengths (read more about white light and plant growth), which gives quantum lights an advantage over “blurple” LEDs. But more powerful white LEDs, like COBs, get much deeper penetration than quantum boards.

Open Build

Quantum boards are very simple. LED diodes are affixed directly to a board. Nothing more. There are no covers or lenses.

The diodes are open and exposed and, in many cases, so are the wires. A few of the manufacturers have recently begun adding plastic covers over the exposed wires, but many still have the wires open. All of this means the components are less protected. But it does keep costs down.

Misconception About Heat

While LED lights run cooler than other types of lighting, they still emit large amounts of heat. And quantum boards are no exception.

There is a misconception that they run cool, because they do not need fans, but the diodes still heat up a lot. In general, you can expect about 30% less heat than the equivalent HID light.
