Black Dog LED PhytoMAX-4 4S Grow Light

Description

High-output 250 W LED delivers 531 µmol/s full‑spectrum across 8 wavelengths for compact indoor grows.

The Black Dog LED PhytoMAX-4 4S Grow Light delivers cutting-edge Phyto-Genesis Spectrum technology for growers who demand maximum yield, potency, and efficiency. Unlike standard LED grow lights that rely on basic white and red diodes, this precision-engineered fixture incorporates 8 wavelengths, including UV, violet, blue, red, and infrared, to optimize photosynthesis, terpene production, and plant structure. Whether you’re a small-scale grower or managing a commercial setup, this compact yet powerful light ensures dense, high-quality flower production with industry-leading efficiency.

Is the PhytoMAX-4 4S Energy-Efficient?

Absolutely. By delivering targeted, high-efficiency wavelengths while eliminating excess heat and energy waste, the PhytoMAX-4 4S significantly outperforms traditional HID and LED alternatives. With a long-lasting LED lifespan of 70,000+ hours, redundant cooling fans for fail-safe operation, and Colorado-assembled quality, this grow light is the ultimate tool for growers serious about pushing their plants to the next level.

Features

• Optimized for high yield per watt while enhancing terpene, pigment, and resin production.
• Dimmable from 15% to 100% using industry-standard 0-10V dimming controllers for precise lighting control.
• Advanced active cooling system boosts efficiency and extends LED lifespan, featuring multiple redundant fans for reliability.
• Proven expertise since 2010 as one of the longest-standing LED grow light manufacturers.
• Specialty UV and violet LEDs designed for enhanced plant growth and consistent long-term performance.

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 minimizes 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.
