discontinued. Check out these other great
Optic LED Grow Lights instead.
Optic LED’s Slim 720S LED grow light has been designed and engineered to deliver the best performance of any comparable LED grow light on the market today. For growers who are looking for industry leading results, the 720S features Samsung's latest horticulture series LED tech with 3000+ LEDs and a powerful Meanwell driver.
The Slim 720S is created specifically for 5’ x 5’ grow spaces or for a 4’ x 4’ space where the grower wants to be able to raise the light up for improved cross lighting and uniformity or even growers who just want power to spare in their 4' x4' space.
This LED grow light boasts the coolest running system yet! The Slim 720S is equipped with 3,096 of Samsung's all-new, record-breaking LH351H V2 660nm Deep Red LEDs at 3.75 umols/j and LH351H 450nm Royal Blue LEDs paired with the Samsung White LM301H LEDs. This is the only 700+ watt LED grow light with a efficiency rating of 3.0 umols/J or higher thanks to its 3,096 LEDs.
The Slim 720S is dimmable from 0 to 100%, with separate control for red, white and blue. Turn up the blue dimmer early in veg for thicker stems, tighter node spacing, and bushier plants with increased yields. Keep the blue turned up early in flower then crank up the Samsung deep red LEDs to give you incredible growth in the flowering phase with dense buds and high yields.
Pair the Slim 720S with Optic LED’s touch screen master controller for precision control to mimic natural light and light cycles. The fully programmable dimmer lets you set the light intensity you want when you want it. You also have the option to manually dim your lights simultaneously or adjust the red or the blue LEDs alone to make the most of this light’s innovative spectrum tunability. You also have the option to have use Auto Sunrise and Auto Sunset from the controller’s flexible option menu.
