Focused Light, Deeper Reaching: The Micro-Lens Optic System uses curved, wave-shaped lenses to redirect and concentrate light, boosting PPFD by up to 20%; Light is then spread evenly and pushed deeper into the canopy, helping every plant photosynthesize efficiently and develop stronger

Optimized Full Spectrum: With white, blue, red, and far-red LEDs (3000K, 5000K, 660nm, and 730nm), this grow tent light provides full-spectrum illumination to support photosynthesis from early growth to harvest; It speeds up flowering time and increases yields

Sealed Protection & Longer Lifespan: Fully sealed light bars with an IP65 waterproof protect LEDs from dust, mist, and cleaning exposure, making maintenance easy; Integrated heatsink fins improve airflow and reduce heat buildup, helping extend lifespan up to 36,000 hours (Q90)

Upgrade your indoor grow with this high-performance LED grow lamp, available in 320 W, 500 W, and 750 W to perfectly match 3×3 ft, 4×4 ft, and 5×5 ft grow tents. Featuring the Micro-Lens Optic System, precision-curved lenses concentrate light for high-intensity output, while wave-shaped optics spread it evenly and drive light deeper into the canopy. This means stronger PPFD, fuller plants from top to bottom, and more consistent results every cycle. The bar-style design delivers smooth, edge-to-edge coverage with no harsh hotspots. Built for grow tents, the fully-sealed light bars resist spray, mist, and cleaning chemicals, so you can clean and maintain your space without interrupting operation.
