- Increases yield over a 600W HPS while using 35% less electricity
- LED grow lights save on electrical, cooling, reflector and bulb replacement costs
168 High-Output 5-watt LEDs
- Every top-bin LED is selected from the industry leader for the particular wavelength, including Cree, Osram, etc.
- With glass lenses for durability and cleanability
- High light intensity and energetic spectrum, crucial for canopy penetration to nourish lower leaves and flowers
- Even, edge-to-edge coverage eliminates leaf burn and hot spots
- 420 True Watts - 840 LED Watts
Large Coverage Footprint
- Up to 4.25' X 4.25' (18 square feet!) of flowering footprint coverage!
- Proven by independent spectroradiometer testing
- The most efficient light spectrum for growing plants, based on over 6 years of research and testing, outperforming HPS, MH, CMH (LEC), induction, fluorescent, and "white", so-called "full-spectrum" LEDs in equal wattage tests
- One ideal spectrum for both vegetative and flowering stages eliminates stalling associated with spectrum changes such as switching from MH to HPS
- True full spectrum ranging from UVA to NIR (365-750nm) goes Beyond PAR™ for ultimate flowering and vegetative plant cycles
- Appears white to human eyes, allowing easy determination of plant health
- Targets not only photosynthetic (chlorophyll / carotenoid) peaks but also:
- Increases flavonoids, antioxidants / vitamins and pigmentation with UV light
- Includes near infrared (NIR) light to boost photosynthetic efficiency through the Emerson Effect
- Decreases internodal spacing to direct more of your plants' energy to flowers and leaves, instead of stems
Commercial Grade LED Grow Light Panels

Processing time is the time it takes from when you submit your order to when the product leaves the warehouse. The "Ships Within" time frame listed with each of our products on the website applies to this time frame. For example, if your order a product that reads "Ships Within: 2 Weeks", this means that the product typically leaves the factory within two weeks.
