Black Dog LED PhytoMAX-4 2S Full Spectrum LED Grow Light
The PhytoMAX-4 2S LED Grow Light is a high-powered LED grow light that uses a unique Phyto-Genesis Spectrum to promote compact, bushy plants with high yields. The spectrum includes 8 different colors of light that target specific responses from the plants, known as photomorphogenesis. The light also includes 3% ultraviolet light (<400nm) that mimics the sun's natural UV light, keeping plants bushier and more compact, more resistant to pathogens and insects, and producing more terpenes and pigments. The light also includes infrared / far red light (700-750nm) that increases photosynthetic efficiency through the Emerson Effect.
PhytoMAX-4 2S Features
Unparalleled Yield and Quality
PhytoMAX-4 lights are designed to grow the highest-quality and highest-quantity harvests. Rather than striving for the highest-possible photons per watt, PhytoMAX-4 is designed to give the highest yeild per watt while maximizing terpenes, pigments and cannibinoid production.
Black Dog has been perfecting grow lights and supporting the industry since 2010 - they’re among the oldest LED grow light manufacturers still in existence.
Dimmable from 15% - 100% with industry-standard 0-10V dimming controllers.
PhytoMAX-4 increases efficiency and maximizes lifespan by actively cooling the LEDs. Cooler LEDs run more efficiently and have a longer lifespan, especially for the specialty UV and violet LEDs we use. While fans are a moving part, we've never had one fail in tens of thousands of lights over the past 13 years, plus our patented design includes multiple redundant fans. Even if one were to fail, your light will keep running just fine.
Designed and Assembled in Colorado
PhytoMAX-4 utilize only the highest-quality parts and have been perfecting the design for over 8 years- these lights are built to last!
Go BEYOND PAR with the Phyto-Genesis Spectrum
The Phyto-Genesis Spectrum has been finely-tuned to not just grow plants, but to grow more-compact, more-productive and higher-quality flowers, fruit and leaves. Unlike most LED grow lights that use white or white and red LEDs, we incorporate 8 different LED colors to target specific responses from the plants, known as photomorphogenesis.
Our spectrum triggers plants' hormonal response to different colors of light and the ratio of these colors to minimize stem growth while maximizing flower and fruit production. Compact, bushier plants are not only easier to work with but also maximize yield per square foot.
3% Ultraviolet light(<400nm) mimics the sun's natural UV light, keeping plants bushier and more compact, more resistant to pathogens and insects, and producing more terpenes and pigments.
Unlike supplemental UV light bars, PhytoMAX-4 evenly distributes UV light across the entire growing area, and at a concentration that gives your plants the benefits of ultraviolet throughout the entire growing cycle, not just restricted to the last couple weeks of flower.
Infrared / Far Red
Infrared / far red light (700-750nm) increases photosynthetic efficiency through the Emerson Effect. Too much can cause stem elongation but when paired with the right ratio of red and blue light as in the Phyto-Genesis Spectrum, it increases yields.
Violet light (400-450nm) better penetrates dense plant canopies to nourish lower leaves, allowing high-quality flowers and fruit to grow lower on the plant.
Blue light (450-480nm) triggers chlorophyll B photosynthesis more efficiently than green or yellow light, and helps keep leaves more compact for better canopy penetration.
Red light (600-700nm) drives photosynthesis, but can also cause plants to elongate their stems if not matched with an appropriate amount of blue light.
The 4S grow light is dimmable from 15% - 100% with industry-standard 0-10V dimming controllers.
This incredible light is capable of producing up to 7+ pounds per light (depending on strain, environment and growing skills).
Standard Power Inlet
The PhytoMAX 2S is equipped with an IEC standard power inlet, allowing cords to be sourced worldwide.
SP vs SC model
The only difference between the SP and SC models is the power cord and the voltage it can handle.
SP model IEC Power cord:
