SUNGROWN SERIES
The Sun, Engineered.
270W Grow LED Panel
We couldn't find the perfect grow light — so we built it. Samsung LEDs. Osram deep red. Real UVB. Zero compromises.
😤 Tired of LEDs that promise the sun but deliver a desk lamp?
Most "full-spectrum" LEDs skip the wavelengths that actually matter. No real UVB. Weak deep red. Generic diodes. The result? Pale harvests, muted flavors, and wasted electricity.
🌱 This is what happens when growers engineer their own light.
Every wavelength is deliberate. Every component is best-in-class. The result? Denser flowers, richer terpenes, and harvests that speak for themselves.
THREE CIRCUITS, ONE PERFECT SPECTRUM
Light that works the way nature intended
The Sungrown Series blends three precision-tuned circuits into a seamless, sun-mimicking spectrum — from deep UV to far red.
512 Samsung LM301H LEDs in a calibrated 3000K + 5000K blend. Full-spectrum power for every stage — from vigorous veg to heavy flowering.
SAMSUNG LM301HOsram 660nm deep red supercharges flowering. 730nm far red triggers the Emerson Effect — accelerating photosynthesis beyond visible light alone.
OSRAM 660nm + 730nmReal UVA + UVB from Seoul Semiconductor. UVB acts as a natural stressor — triggering the same responses plants develop at high altitudes.
SEOUL UVA + UVB
More Terpenes. More Aroma. More Flavor.
UVB isn't a gimmick — it's the secret weapon of high-altitude and equatorial growing. Our calibrated UVB triggers a cascade of adaptive plant responses, amplifying terpene production and unlocking the full aromatic potential of your harvest. Most LEDs only offer UVA. This one gives your plants what the sun actually gives them.
COMPONENT BREAKDOWN
Only best-in-class parts make the cut
Every diode was selected for a reason. No filler LEDs. No cheap drivers. Just the components professional growers trust.
LM301H
512× Samsung LM301H — The Gold Standard
The most efficient white LED in the grow industry. 352 warm-white (3000K) + 160 cool-white (5000K) for a rich, plant-optimized full spectrum that drives both vegetative growth and heavy flowering.
352× at 3000K 160× at 5000K
DEEP RED
60× Osram Supplementary LEDs
24 units at 660nm target the exact absorption peak for flowering, maximizing bud density and yield. 36 units at 730nm leverage the Emerson Effect — a proven photosynthetic boost that makes your entire spectrum work harder.
24× at 660nm 36× at 730nm
UV
20× Seoul Semiconductor UV LEDs
12 UVA + 8 UVB diodes deliver the ultraviolet wavelengths most grow lights completely ignore. This is what separates harvests that taste "okay" from harvests that rival outdoor, sun-grown quality.
12× UVA 8× UVB
BUILT FOR REAL GROWERS
Every detail, dialed in
🎛️ Full Spectrum Control
Stepless dimming knob (30%–100%) plus side-lever switches for independent channel control: Full Spectrum, Base + Deep Red, Infrared, and UV. Dial in the perfect light recipe for every growth stage.
🤫 Whisper-Quiet Operation
Enlarged passive cooling surface means zero fans, zero noise. Air-cooled design runs silent without sacrificing a single watt of performance.
❄️ Runs Cool, Saves Energy
Dramatically less heat than HPS. No need for oversized exhaust fans. Your tent stays cooler, your energy bill stays lower, and your plants stay happier.
📐 Compact, Plug-and-Play
At just 63 × 20.7 × 9 cm and 5 kg, it fits tight spaces with ease. Comes with hanging wire and EU plug — unbox, hang, grow.
Replaces Your 400W HPS — At Half the Power
Covers up to 1m × 1.2m with intense, uniform light. All the output, fraction of the heat and electricity.
