Get to Know the Black Dog PhytoMAX-4 24S LED Grow Light

Meet the powerhouse of the PhytoMAX-4 line—the Black Dog LED PhytoMAX-4 24S. At 1500W and 3188 µmol/s PPF, this full-spectrum grow light delivers maximum intensity for high-yield, high-quality cultivation. Featuring Black Dog’s proprietary Phyto-Genesis Spectrum, this fixture optimizes plant growth with 8 wavelengths, including UV, violet, blue, red, and infrared. Whether you're maximizing a commercial grow space or fine-tuning an advanced home grow, the 24S ensures explosive yields and exceptional cannabinoid production.

Is the PhytoMAX-4 24S Energy-Efficient?

At 2.1 µmol/J, the 24S delivers one of the best efficiency-to-output ratios in the industry. Running at 1500W, it outperforms 2000W+ HID fixtures while using 30-40% less HVAC capacity. Plus, with a power factor of 0.99, it minimizes wasted energy, making it a cost-effective choice for serious cultivators.

Features

  • Optimized yield per watt to maximize harvest quantity and quality while enhancing terpenes, pigments, and cannabinoid 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.

What's Included?

  • PhytoMAX-4 24S LED Light Fixture

FAQs

How many watts do I need for my grow space?

The wattage depends on the size of your grow tent or room. A general guideline is 30-50 watts per square foot for high-light plants like cannabis. For example, a 2x2 ft area may need 100-200W, while a 4x4 ft area may require 400-600W for optimal coverage.

What is the difference between full-spectrum and red/blue LED grow lights?

Full-spectrum LED lights mimic natural sunlight, providing a balanced mix of blue (for vegetative growth) and red (for flowering and fruiting) light. Red/blue LED lights focus on specific wavelengths but may not support plants as effectively as full-spectrum lights.
