The Slim 320H Gen2 Veg 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 Veg 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.
