What is a quantum board? A Quantum board is a lighting innovation devised by Horticulture Lighting Company (HLG) and adapted by other brands. It is also one of the newest concepts in the grow light industry, and its popularity is undeniably astounding, especially with indoor cannabis growers.
Quantum board LED grow lights differ from one brand to the next, with HLG quantum board models leading the pack with high-quality components. The grow lights mount on diode circuits in series containing powerful LEDs making a string of full-spectrum lights that mimic the sun’s natural sunlight. Quantum boards come with several other advantages and a few disadvantages, which do not prevent them from performing exceptionally well.
One of the reasons for its popularity is the high cannabis yields, which is much higher, compared to the yields realized when using the standard LED grow lights. Another reason for the popularity of quantum boards is its low energy consumption making it one of the best high-energy efficient grow lights.
We checked out and reviewed some of the best quantum board led grow lights on the market, and here is our take.
Our Top Picks
SPIDER MARS SF-4000 LED Grow Light
Spider Farmer is a leading LED grow light contender and manufacturer in the industry of quantum board grow lights. It is famous for its reliable technology and effective products that offer unbeatable quality at fair prices. However, the costs of the majority of spider Farmer products are steep for first-time growers.
The SF-4000 led grow light is one of the best contenders in the quantum board technology LED light market and the largest on the SF line of grow lights. One of its standout features is its efficiency and fantastic energy consumption, which is only 456 watts. Furthermore, it is also one of the most affordable quantum LED grow lights to operate irrespective of its high-quality features and efficiency.
During the vegetative phase, the grow light accommodates a footprint of 6 by 6 feet and 5 by 5 during the flowering stage, making a total coverage of 36 square feet. Samsung diodes LM301B, some of the grow light leading technology on the LED grow light market, are the primary light sources for the quantum board. The quantum board has a long lifespan of over 50,000 hours, which is the equivalent of five years.
Another feature that makes the quantum board an excellent asset for cannabis growers includes a protective coating on the chips board, making it waterproof. It has shockproof covers on its wires for added users’ safety, a dimmable MEAN WELL driver, and a three-year warranty covering craft and material defects. Lastly, the light does not include cooling fans among its features, giving it a quiet performance. It has an aluminum heat sink for heat dissipation instead.
Pros
- Quiet operation
- Provides full-spectrum light
- Energy efficient
- Waterproof
- High output
Cons
- It is costly, especially for beginners
