The Optic 1 XL Dimmable 3500 K COB by Optic LED is a precision-engineered 100-watt grow light built around a high-output CREE XLamp CXB3590 COB with 3500 K full-spectrum white light. Its ultra-efficient design pushes nearly 2 µmol per joule while delivering up to 549 µmol/m²/s PPFD over a 2' x 2' flowering area and full coverage up to 4' x 4' in the vegetative phase. Designed for whisper-quiet performance, the fixture operates passively cooled via a robust anodized pin-fin heatsink, eliminating the need for noisy fans. Power is driven by a premium Meanwell dimmable driver, offering smooth, quiet adjustment from 10% to 100% to suit all growth cycles. If you’d prefer to try out something different from them, don’t hesitate to check out their Slim 320S LED Grow Light or Phantom 1XL Dimmable systems.
