Go BEYOND PAR with our Phyto-Genesis Spectrum

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 colours to target specific responses from the plants, known as photomorphogenesis.

Our spectrum triggers plants' hormonal response to different colours of light and the ratio of these colours 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.


SP versus SC Models

The only difference between the SP and SC models is the power cord and the voltage it can handle.

SP model IEC power cord:

  • Rated for 100-250 Volts
  • Not recommended for greenhouse use

SC model locking, water-tight power cord:

  • Rated for 100-277 Volts
  • Locking, water-tight connection


Photon Flux (μmol/s)

  • PBAR 280-800nm: 1062
  • UV 280-400nm: 31
  • PAR 400-700nm: 952
  • IR 700-800nm: 79

Unparalleled Yield and Quality

  • The Black Dog PhytoMAX-4 LED Grow Lights are designed to cultivate crops of the highest quality and highest yields. Rather than solely pursuing the highest possible photon output, the PhytoMAX-4 is engineered to provide the greatest yield per watt while optimizing the production of terpenes, pigments, and cannabinoids. 


  • Black Dog has been refining grow light technologies and supporting customers since 2010, placing us among the most experienced LED grow light manufacturers in the industry. 

Unmatched Customer Support

  • We have cultivated thousands of unique plant varieties with our products and provide best-in-class customer support for questions about lighting setups and horticultural issues. Whether you are growing four plants or 40,000, our team offers the knowledge to assist.

Precision Dimming Control 

  • The lights are dimmable from 15% to 100% using industry-standard 0-10V dimming controllers for customized lighting profiles.

Reliable, Active Thermal Management

  • The Black Dog PhytoMAX-4 LED Grow Light increases efficiency and longevity through an active cooling system for the LEDs. Cooler LEDs perform more efficiently and last longer, especially specialized UV and violet LEDs. While fans are movable components, we have never experienced a failure across tens of thousands of units over 13 years of use. Furthermore, our patented design incorporates redundant fans to ensure continuous operation even if one were to malfunction.

Designed and Assembled in Colorado 

  • We utilize only top-tier components and have refined the Black Dog PhytoMAX design for over eight years to create a product built to withstand long-term use.

Hanging Hardware Included

  • Each light includes a set of V-hooks and ratcheting rope hangers for effortless installation.
