500 W full‑spectrum LED delivers 1063 µmol/s with 8‑wavelength Phyto‑Genesis Spectrum for powerful medium-area yields.

For growers who refuse to compromise on yield and quality, the Black Dog LED PhytoMAX-4 8S Grow Light delivers unparalleled performance with its Phyto-Genesis Spectrum. Unlike traditional LED grow lights that rely on basic white or red diodes, this powerhouse combines 8 wavelengths—including UV, violet, blue, red, and infrared—to maximize photosynthesis, terpene production, and overall plant health. Designed for hobbyists and commercial growers alike, this 500W full-spectrum grow light offers a 15" x 15" footprint with industry-leading active cooling to ensure long-lasting efficiency and reliability.

Is the PhytoMAX-4 8S Energy-Efficient?

Absolutely. Unlike HID lights that waste energy as heat, this LED fixture is optimized for maximum light absorption with minimal power draw. Its 0.99 power factor ensures efficiency across all voltages, while cooler-running LEDs increase longevity and maintain high performance. Whether you’re growing 4 plants or managing 40,000, the Black Dog LED PhytoMAX-4 8S is the ultimate choice for serious growers looking to push their harvests to the next level.

Features

  • Optimized for maximum yield per watt while enhancing terpene, pigment, and cannabinoid production.
  • Dimmable from 15% to 100% with industry-standard 0-10V dimming controllers for precise light control.
  • Reliable active cooling system extends LED lifespan and improves efficiency, featuring multiple redundant fans for uninterrupted operation.
  • Designed and assembled in Colorado with premium components for long-lasting durability.
  • Over a decade of expertise from one of the oldest LED grow light manufacturers, providing top-tier customer support for all growers.

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.

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.
