Black Dog LED PhytoMAX-4 20S Grow Light

Description

1250 W full‑spectrum LED delivers 2657 µmol/s and 8‑wavelength Phyto‑Genesis Spectrum for elite commercial yields.

The Black Dog LED PhytoMAX-4 20S delivers 2657 µmol/s PPF with 1250W of power, ensuring maximum light intensity and efficiency for high-yield cultivation. Designed with the proprietary Phyto-Genesis Spectrum, this full-spectrum LED grow light optimizes photosynthesis, terpene production, and plant structure. Whether you’re managing a commercial grow or an advanced indoor setup, the 20S delivers superior canopy penetration, even light distribution, and industry-leading performance.

Is the PhytoMAX-4 20S Energy-Efficient?

At 2.1 µmol/J, the 20S operates with higher efficiency than traditional HID fixtures, offering 30-40% HVAC savings while providing higher PPFD levels for maximum yields. With dimmable control and optimized cooling, it ensures consistent performance with lower energy costs, making it an excellent investment for serious cultivators.

Features

• Optimized yield per watt to maximize harvest quantity and quality while enhancing terpenes, pigments, and resin production.
• Dimmable from 15% to 100% with industry-standard 0-10V dimming controllers for precision light adjustment.
• Advanced active cooling system ensures efficiency and extends LED lifespan with multiple redundant fans.
• Specialty UV and violet LEDs designed for superior plant growth and long-term performance.
• Over a decade of expertise from one of the longest-running LED grow light manufacturers, delivering proven reliability.

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.

SP versus SC Models

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