The term “quantum board” was first introduced by Horticulture Lighting Group (HLG for short), a relatively new supplier of LED grow lights. It referred to a new style of light where a large number of small LED diodes are affixed to a flat board.

In simple words, Quantum boards are small pieces of boards that are lined up with the LED chips. These chips are spread all over the boards. This way that they get their power supply simultaneously from the same source. Most indoor growers buy quantum board LED grow lights to illuminated their plants and ensure they blossom well.

A quantum board LED is a newer alternative to the more expensive COB grow lights. The quantum board is a large circuit board in which a string of LEDs are connected forming “intelligent spectrum string” resulting in a broader spectrum and bigger plants. True full spectrum is the result.

If you’re in the indoor grow industry, there is a high chance that you’ve heard of “Quantum Board LED Grow Light”. Quantum Board LED grow lights have continued to grow in popularity since the Horticultural Lighting Group first introduced them in the market.

Or if you are one of those people who tirelessly follows trends and knows everything about them, then you have surely heard of the quantum board led grow lights.

The whole medicinal plants growing community is buzzing about these led lighting boards. You can read incredibly good reviews and experiences with these lights on forums, blogs, and you can even see them on YouTube videos.

The point is that everyone is thrilled with these quantum lights and guaranteed to work miracles!


Some benefits of quantum boards are:

  1. Efficiency

Quantum board give you more output while consuming fewer watts. 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.

  1. Light Spread

Because the light emanates from many points across a large board, it has a more direct path to the canopy on the outside of the coverage area than a light that comes from a smaller fixture and has to emanate further outward.

This results in less intensity in the middle of the coverage area and more intensity around the outside.

  1. Spectrum

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. 

  1. Simple Heat Management

Some grow lights emit a lot of heat and end up causing leaf burn, but, quantum boards are generally mounted to a to a thin piece of aluminum (or sometimes a heatsink), which suffices to passively cool the diodes. No fans are needed (note that the fixtures do still get hot; see disadvantages below).

  1. Low Price

On average, quantum board lights cost less than traditional LEDs or COBs that produce a similar output. Yes, there are far cheaper lights, but those lights do not come close to giving you the output of a quantum board.


If you have been in the growing business for a while, you must have become interested in quantum board grow light at some point. Below some of the best quantum led grow lights are here which can give you necessary information for buying grow lights for your indoor grow rooms.


ECO Farm 110W/220W/460W/600W Full spectrum Samsung 301B Quantum Board With Daisy Chain For Indoor Plants


Upgraded ECO Farm 10W/220W/460W/600W quantum board have a dimming knob and light switch. A single light can be adjusted the light intensity at liberty. Multi-light Connection with unified dimming especially beneficial for large area of indoor growing and commercial planting.

Excellent full spectrum provide more  light. The light is especially useful during bloom, where it speeds up flowering time and boost yields. Uniformly across the surface and deep into the roots and bottom of canopy for consistent, highest quality flowers.

Proper use of UV IR containing luminaires to ensure your plants grow better and increase the amounts of THC, and terpene production in medicinal plant.

The importance of UV: UV can have positive effects. It improves the colouring of ornamental crops. And, very importantly, it improves their resistance to diseases.

The importance of IR: IR light gives your plants a little bit of heat radiation that actually stimulates plants' growth.

High performance

Full Spectrum: close to natural sunlight

Quick heat dispersing made by aluminum

Suitable for all the growth stage of plants.

UVIR can be controlled separately

Back wiring is waterproof
