The Slim 320H 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. Black Rails on both sides of the Light give it a really aggressive look with the white Slim 320h Logo and the Meanwell, Samsung & CREE Logos on both ends of the light.

It is powered by a "Best in Class" Meanwell HLG 320H Dimmable Driver, giving you many years of reliability and top of the line efficiency.

The Slim 320h Represents the integration of the best from CREE, the best from Samsung, and best from Meanwell.

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 CREE XPE LEDs are the most efficient "mainstream" Multicolored LED used today. The Slim 320H features CREE's 460 nm deep blue and 660 nm deep red for a balanced spectrum that can be absorbed in ultra-high intensities, and results in the best possible flower quality, and density.

  • Samsung LM301H LEDS: 1344 diodes with a mix of 3000K and 4000K white light
  • CREE XPE LEDs: 12x 460 nm royal blue and 24x 660 deep red
  • 120 degree lens: each Samsung and CREE diode has a 120 degree lens for protection and to focus the beam for better efficiency
  • Meanwell driver: top of the line MeanWell HLG Series 320 watt dimmable driver (remote mountable)

  • 10-year warranty: you'll see other stores call it a lifetime warranty, but read the fine print...it's 10 years
