Slim 650S - Dimmable LED Grow Light - 650w - (UV/IR) With Spectrum Control

650 Watt Dimmable LED Grow Light

International Orders: (Ships by Dec.2nd)


           Slim650S is engineered to give you performance far beyond what any other LED Grow Light company has in the market today including the new Samsung LH351H Deep RED LEDs rated at 3.1 umols/J Paired with the Samsung White LM301H LEDs which are above 3.0 umols/J with a 3way dimmable system. Slim 650S is by far the most advanced LED Grow Light ever manufactured. Slim 650S gives growers the power to recreate mother nature with precision accuracy.

          Slim 650S is the first-ever Bar Light Fixture to deliver 3 Way Spectrum Control with Independent Dimmers for Red, Blue, and White LEDs. Early in VEG when you're looking to get that extra lush and vigorous growth you can crank up the blue dimmer to give you thicker stems, tighter nodes, and bushier plants. Early in flower if your plants are stretching too much you can also turn up the blue LEDs for less stretching. Then you can unleash the Samsung Deep Red LEDs to give you amazing flowering production, Dense buds & heavyweight yields. The list of benefits goes on, Slim 650S is in a very special class of LED Grow Lights that offer true spectrum control. 

          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 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 partnership with Samsung and using their newest record-setting technology with full transparency.
