  Optic 8+ 500 watt dimmable COB LED Grow Light. Optic LED has now seamlessly integrated eight of CREE's highest yielding COBs (XLAMP CXB3590) with industry leading glass optical lenses to give you unprecedented light penetration. The combination of these two technologies combined with proprietary blend of 3 watt Osram LEDs will give you significantly improved grams per watt yield and significant increases in bud density, coloring of your flowers and overall quality of trichomes.
