Optic Led Slim 650S – Dimmable LED Grow Light – 650w (Triple Dimmer)


Optic Led Slim 650S – Dimmable LED Grow Light – 650w (Triple Dimmer) 3500K (UV/IR) LH351H V2


Optic Led Slim 650S is engineered to give you performance far beyond what any other LED Grow Light company has in the market today including Samsungs all-new record-breaking 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 with a 3way dimmable system running 3,096 LEDs total for next-generation efficiency and tuning capabilities. Slim 650S is by far the most advanced LED Grow Light ever manufactured. Slim 650S when combined with our touch screen master controller gives growers the power to recreate mother nature with precision control.


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, you can crank up the blue dimmer to give you thicker stems, tighter node spacing, and bushier plants that yield better in flower. 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 collaboration with Samsung and using their newest record-setting technology with full transparency from their Horticulture Specific Line of LEDs.
