HLG 550 v2 Quantum Board vs. Green Sunshine ES300 LED Grow Light
Horticulture Lighting Group
Horticulture Lighting Group is credited with designing the “quantum board” LED grow light. A quantum board design is simply LEDs spaced evenly in rows on a LED panel. The idea is to spread light more evenly across the canopy.
The company currently offers a product line of quantum boards ranging from the small HLG 65 to the large HLG 550 V2. They also offer DIY quantum board kits if you’d prefer to use their boards to make your own setup.
In contrast to COB LED grow lights and red/blue spectrum LED grow lights, the quantum board has no cooling fans, no intensifying lens, and produces a complete white spectrum. Quantum boards are typically more efficient when considering power usage to light output.
Quantum boards are now one of the most popular options when it comes to LED grow lights. Many people who switched from red/blue spectrum LED grow lights claim to notice a considerable increase in yield. HLG Quantum Board is popular with growers.

This unit is dimmable, with wattage output from 200 to 480 watts.
The Green Sunshine Company offers a smaller line of LED grow lights, but man are these light high quality! The design of the Electric Sky ES300 is similar to a quantum board design in some ways, although I don’t know that I’d classify it as a quantum board. At least The Green Sunshine Company doesn’t classify it that way.green sunshine logo
With that said, growers are migrating more quickly towards Green Sunshine’s lights as word spreads and as people learn more about quality light spectrum from growing cannabis.
I usually provide a bit of background on these companies so people are more confident about the product they’re inquiring about. There are a lot of cheap LED grow lights on the market that simply don’t provide the whole spectrum or level of light intensity that’s needed to maximize your yield. When you get to the higher end companies like Green Sunshine and Horticulture Lighting Group, you really don’t need to worry about that.
Green Sunshine Electric Sky ES300 V2
The Electric Sky 300 (ES300) is The Green Sunshine Company's flagship 300 watt LED grow light – a triumph for the indoor garden. Each Electric Sky evenly illuminates a rectangular grow area with a special recipe of color that grows plants bigger and faster. It has no moving parts, is easy-to-use and grows with excellent results from seed to flower. Plants like exotic flowers, peppers, and leafy greens will flourish under the Electric Sky with a wideband spectrum geared for high yield.
Which spectrum is better?
While there may not be an answer on the absolute best spectrum design, it’s fair to say both these lights emit a high quality spectrum. The HLG 550 v2 emits an impressive white spectrum that customers really speak highly of. The Green Sunshine ES300 also has an innovative and quality spectrum design that its customers really love. It’s a tie on spectrum.
Which light intensity is better?
When comparing the light intensity charts above, the ES300 was measured inside a grow tent, which increases light intensity due to reflective mylar inside the tent.
In comparison, the HLG 550 was not measured inside a tent. So if you’re planning to use the HLG in a grow tent, you can consider that those intensity readings shown above will come in slightly higher, which really makes the HLG a closer competitor to the ES300.
Final thought
These are both really great lights. If I had to pick between the two I’d be tempted to go with the Green Sunshine ES300, simply because the even spread of intense light over the entire canopy is a rare feat. At the same time you’re saving on the price compared to the HLG 550 v2 quantum board as well.
No matter which you pick, both grow lights have very enthusiastic owners so I think you’ll be happy either way.
