The Slim 320S Gen3 Dimmable LED Grow Light is a top of the line LED Fixture that is sure to amaze. Now upgraded (July 2022) with triple dimmer.
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.
