The Optic LED Optic 1 XL 3500 K COB is a compact and high-efficiency grow light built around a single CREE XLamp CXB3590 COB LED, engineered to deliver powerful output with minimal heat and no fan noise. Operating at a true 100 W draw with a commercial-grade Meanwell dimmable driver, it achieves a photon efficacy near 1.97 µmol/J and generates average PPFD values of approximately 549 µmol/m²/s at 16.5″ in a 2x2 ft flowering footprint. Designed for clean performance and long life, its overbuilt anodized black pin‑fin heatsink improves thermal control and extends COB lifespan by over 25%, while a precision 90° glass lens directs light deep into the canopy for better quantum efficiency and even coverage. Optic LED provides many lighting solutions for growing environments.
