The Slim 320S Dimmable LED Grow Light is a top of the line LED Fixture that is sure to amaze.

This all aluminum fixture is lightweight, sleek, and built to provide maximum passive cooling capabilities for the Optic Double Row LED Strips.

It is powered by a "Best in Class" Meanwell Dimmable Driver, giving you many years of reliability and top of the line efficiency.

Samsung's horticulture specific LM301H white LEDs are in the class of "Most Efficient" from Samsung and they go through a special lens treatment to stand up to high humidity environments.

The Samsung LH351H are the most efficient "mainstream" Multicolored LED used today. The Slim 320S features 450 nm deep blue and 660 nm deep red, plus UV.

This gives you the perfect balanced spectrum that can be absorbed in ultra-high intensities, and results in the best possible flower quality and density.

 

Optic Slim 320S Features

  • Samsung LM301H LEDS: 1344 diodes with a mix of 3000K and 3500K white light
  • Samsung LH351H: 16x 450 nm royal blue and 24x 660 deep red
  • LG UV LED: 4x UV for increased resin production and potency of oils
  • 120 degree lens: each diode has a 120 degree lens for protection and to focus the beam for better efficiency
  • Meanwell driver: top of the line MeanWell dimmable driver (remote mountable)
  • Large coverage: 2 by 4 foot coverage area
  • Dimmable: 2x dimmers go from 0 to 100% - one for red and warm white, the other for blue and cool white
  • Yield: Up to 768 grams / 27.42 oz /  1.71 lbs (2.4 grams per watt)
  • Highly efficient: 320 watt power consumption (at 100%), but is equivalent to 600 watt HID; 2.1 umol/joule
  • 10-year warranty: you'll see other stores call it a lifetime warranty, but read the fine print...it's 10 years
  • Controller Port: use Optic's 7" Touchscreen Optic LED Master Controller to control light(s) remotely (but not required, you can also use the settings directly on the fixture); add the controller option above to save $100 over buying it separately
