Optic LED Slim 650S Dimmable LED Grow Light 650W (120 Degree) 3500K

The Optic LED Slim 320S has been discontinued. Check out these other great Optic LED Grow Lights instead.

Optic LED’s Slim650S has been designed and engineered to be one of the highest-performance LED grow lights on the market. It features Samsung's all-new LH351H version 2 660nm Deep Red LED Chips at 3.75 umols/j and LH351H 450nm Royal Blue LEDs paired with the Samsung White LM301H LEDs which are above 3.0 umols/J! Pair this with a 3-way dimmable system running 3,096 LEDs and you get ground-breaking efficiency and tuning capabilities. Slim 650S when combined with our touch screen master controller gives growers the power to recreate mother nature with precision control. The Slim 650S could be called the most advanced LED Grow Light ever manufactured.

The Slim 650S is the first grow light of its kind to offer 3-way spectrum control with independent dimmers for Red, Blue and White LEDs. Early in the vegetative growth stage, you can turn up the blue dimmer to encourage tighter node spacing so your plants produce higher yields when flowering. Early in the flowering stage, if your plants are stretching too much because of decreased light intensity then go ahead turn up those deep reds! Samsung Deep Reds will help bring out amazing blooming production as well as dense buds that grow into heavy yields. Perfect for any indoor garden enthusiast or professional indoor farmer looking for high quality results every time without compromise.

The Slim 650S has all the best components in the industry but is also designed to last twice as long as all other grow lights today. Dimmers come standard with the Optic LED Slim series lights as well as the industry's most overbuilt cooling system & top quality, long-lasting Meanwell Drivers. Optic LED was the first mainstream LED Grow Light company to begin using LM301H and now we are the first to publicly disclose our collaboration with Samsung and using their newest record-setting technology with full transparency from their Horticulture Specific Line of LEDs.
