           GMax 300 is an incredible light and is alot of fun to add 1 of these fixtures to any grow space. The Double Dimmer so you have Control of your Red Spectrum and Blue Spectrum independently is extremely convenient and it makes happier plants. Works with the Optic Touchscreen controller for multiple units and the auto sunrise and sunset thats a true game changer in the garden. 

        You will love the way this light looks and operates. The LED Array is super cool, very few lights even have Blue LEDs the Gmax 300 not only has the BLUE Samsung LH351H Chips but has an independent dimmer for them. Dimmer#2 for the RED LEDs, Warm white, Ultra Violet and Infrared can be adjusted right on the fixture itself but also on the touchscreen controller. Amazing Intensity and PAR output shows that you can raise this light up and cover a bigger grow space of 8 or 9 square feet which is 3x3 or 2x4 grow spaces.
