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

Optic LED’s Slim 650S is engineered to give you performance far beyond what any other LED grow light on the market today can offer The Slim 650S features Samsung LH351H Deep RED LEDs (rated at 3.1 umols/J) that are paired with Samsung White LM301H LEDs (rated above 3.0 umols/J) with a 3-way dimmable system running a total of 3,098 LEDS for groundbreaking efficiency and tuning capabilities. The Slim 650S is by far the most advanced LED grow light Optic LED has ever manufactured.

The Slim 650S is the first-ever bar light fixture to offer 3-way spectrum control with independent dimmers for red, blue, and white LEDs. Early in the vegetative stage when you're seeking extra lush and vigorous growth, you can crank up the blue dimmer to give you thicker stems, tighter nodes, and bushier plants. Early in the flower stage, if your plants are stretching too much for example, you can also turn up the blue LEDs to minimize stretching. Then you can unleash the Samsung Deep Red LEDs to give you amazing flowering production, dense buds, and heavyweight yields. The list of benefits is endless with the Slim 650S - a very special class of LED grow light offering true spectrum control.

This LED grow light has all the best components in the industry, but has also been designed to last twice as long as other grow lights. Dimmers come standard with Slim series lights, as well as the industry's most overbuilt cooling system and top quality, long-lasting Meanwell Drivers. Optic LED was the first mainstream LED grow light company to begin using LM301H and they are now the first to publicly disclose their partnership with Samsung and use their newest record-setting technology with full transparency.
