HLG 550 v2 Quantum Board vs. Green Sunshine ES300 LED Grow Light
I wanted to compare two of the more modern LED grow lights that’re popular among the indoor growing community. Word of mouth from growing forums is enough to convince many people to buy a grow light, but here I’ll lay out the differences between the HLG 550 V2 quantum board LED grow light and the Green Sunshine Electric Sky ES300 LED grow light.
What attracted me to these two lights? They’re both modern and among offer the most value for your buck if you have the ability to shop in this price range. You’ll also each light offers solid coverage that doesn’t fade intensity at the edges.
HORTICULTURE LIGHTING GROUP GROW LIGHT
Horticulture Lighting Group actually came up with the “quantum board” grow light design and started the trend among the indoor plant growing community. HLG Quantum board LED grow lights are now one of the most popular grow light choices among dedicated growers. The Horticulture Lighting Group grow light is ETL certified, meaning it meets North American safety standards. The light is put through various electrical, mechanical, normal and abnormal temperature testing to ensure it’s durability and safety.
HLG 550 V2 LED Grow Light
Horticulture lighting group's HLG 550 V2 indoor horticulture Led lamp is designed to replace a single ended 1000W HID. Each lamp uses 4 of our custom designed high efficiency which light quantum boards made by Samsung. 500 watts with 1152 highest output Samsung LM301B Led. Comes in either 3000K (flowering and full cycle) or 4000K (Veg only) spectrums.
TOP FEATURES
- High-efficiency custom-designed white light quantum boards with Samsung LM301B diodes
- 3000K white-light full spectrum for optimal canopy penetration and easy viewing
- Ideal for seedling to harvest growth
- Reliable passive-cooled design (no cooling fans required)
- Optimal canopy penetration with diffused light via a large form factor

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.

- 1x ES300 – Flower 2’x4′ – 3’x5′ Grow Tent / Veg 3.5’x7′
- 2x ES300 (Replace 1000W HPS) – Flower 4’x4′ – 5’x5′ Grow Tent / Veg 7’x7′
- 3x ES300 – Flower 5’x5′ or 4’x6′ / Veg 7’x7′
- 4x ES300 – Flower 4’x8′ – 5’x10′ / Veg 6’x12′
Spectrum
HLG 550 v2 & Electric Sky ES300
Features Compared:
The HLG 550 has four boards, each containing 288 top bin Samsung LM301B chips. So there’s a total of 1,152 on the whole light.The four boards are placed on a larger aluminum panel with a Mean Well driver on the back side. The shape of this board is a square. If you already have a square 4x4 grow tent, the HLG 550 v2 may be more suited for you.
The Electric Sky ES300 has a rectangle design, measuring in at 3 feet long by 1 foot wide. The LEDs are aligned in strips, If you have a 2x4 grow tent, this light is likely the better option.The Green Sunshine ES300 has a full body heat sink, and no cooling fans. Just like the HLG 550 doesn’t need cooling fans, neither does the ES300.
Both of these grow lights are dimmable, although personally I don’t think I’d ever want anything less than full power.
Spectrum Comparison:
Spectrum is one of the most important factors when picking a grow light. With that said, it’s still not a completely settled science, especially when it comes to growing medicinal plants. But high end grow light manufacturers like these have been moving away from the basic red/blue spectrum for what they believe are better spectrums. The comparison of these two grow lights’ spectrum are a prime example.
The HLG 550 v2 and the Green Sunshine ES300 both claim to emit a full spectrum. The HLG 550 v2 is a white spectrum.Studies have shown that white light spectrum (yellow, orange and green wavelengths) added to red and blue wavelengths are more beneficial than red and blue alone.
Don’t worry, white spectrum lights actually include blue and red wavelengths, so you aren’t losing those important wavelengths. You’re simply gaining yellow, orange and green wavelengths along with it.
If I had to pick between the R-Spec and 4000k HLG 550 v2, I’d take the R-Spec based on the spectrum, but they’ll both do a fine job.
The Green Sunshine ES300 utilizes a proprietary wide spectrum light. They say the wavelengths are 420nm to 800nm, which means this light is heavy on infrared. The color breakdown is as follows: Approximately 10% blue, 25% green, 55% red, and 10% infrared. It’s a highly customized spectrum, far from the ‘typical’ blue + red combo you see on most LED grow lights.
Michigan State University ran an experiment to see how useful the inclusion of green light is for plant growth, compared to other common spectrum makeups. Not only did they find that green light *is* useful in photosynthesis, but the salvia plants grown with a majority Green/Red spectrum similar to the Green Sunshine Electric Sky ES300, actually grew 2nd tallest out of 6 different spectrum combinations.
No matter which you pick, both grow lights have very enthusiastic owners so I think you’ll be happy either way.
