Optic LED Optic 8+ 3500k COB Full Spectrum LED Grow Light

Featuring the most advanced COB LED setup from Optic LED, The Optic 8+ 3500k COB LED Grow Light seamlessly integrates eight of CREE's highest yielding COBs (XLAMP CXB3590) with industry leading glass optical projection lenses to give the best light penetration results in the market.

The three independent dimmer functions can make switching from veg to bloom with ease making this the only light setup you would need. In addition, the proprietary blend of 3 watt Osram LEDs will produce greater photosynthesis resulting in significant grams per watt yield.

This combination of features produces an increase in bud density, coloring of your flowers and overall quality of trichomes.
