Compact 125 W full‑spectrum LED delivers 266 µmol/s with an 8‑wavelength spectrum for maximum yield per watt.

Designed for small grow spaces that demand big results, the Black Dog LED PhytoMAX-4 2S is a 125W powerhouse with 266 µmol/s output, fine-tuned for maximum yield per watt. Unlike standard LED grow lights that rely on basic white and red LEDs, this full-spectrum fixture incorporates 8 wavelengths, including UV, violet, blue, red, and infrared, to enhance growth, resin production, and plant structure. Whether you're running a compact home grow or supplementing a larger setup, this high-efficiency grow light delivers deep canopy penetration and optimal light distribution.

Is the PhytoMAX-4 2S Energy-Efficient?

Absolutely. Operating at 2.1 µmol/J, this LED grow light outperforms most HID alternatives in efficiency. Its 0.99 power factor ensures minimal energy waste, while redundant cooling fans keep LEDs running at peak performance. Designed for 70,000+ hours of operation, the PhytoMAX-4 2S delivers commercial-grade results in a compact, ultra-efficient package.

Features

  • Maximized yield per watt with enhanced terpene, pigment, and cannabinoid production for superior harvests.
  • Dimmable from 15% to 100% using industry-standard 0-10V dimming controllers for customizable lighting.
  • Active cooling system improves efficiency and extends LED lifespan with multiple redundant fans for reliability.
  • Proven performance since 2010 from one of the longest-standing LED grow light manufacturers.
  • Specialty UV and violet LEDs designed to optimize plant growth and longevity.

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 vs. 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.
