Who This Is For

  • You are upgrading to high-intensity LED because your small garden isn't hitting commercial-grade yields.
  • You are choosing an active-cooled light because your compact tent traps heat and shortens the life of passive units.
  • You are selecting the SC model because your greenhouse environment requires a water-tight power connection.

What We Found

  • The active cooling fans are quiet enough that you can still hear your pumps cycling in the background.
  • We suggest the SC model for high humidity spots because that locking power connection is genuinely watertight.

What Users Say

  • Growers who switched to this unit say they stopped seeing the leggy growth typical of lower intensity LEDs.
  • Users with height restrictions say the active cooling keeps the canopy cool even when the light is hung close.

Black Dog LED PhytoMAX-4 4S Full Spectrum LED Grow Light

Struggling to achieve professional-grade yields in a limited indoor space? The Black Dog LED PhytoMAX-4 4S provides the high-intensity light and precise spectrum needed to transform small gardens into high-output environments. Designed for passionate growers who refuse to compromise on quality, this fixture delivers the power of a commercial system in a compact, efficient package.

Running at 250 watts, the PhytoMAX-4 4S produces a remarkable 531 µmol/s of light using the proprietary Phyto-Genesis Spectrum. By utilizing eight specific LED colors, it triggers optimized physiological responses in your plants, leading to denser flowers and higher terpene profiles. Whether you are looking for a primary light for a small tent or supplemental lighting for a larger room, this fixture offers the versatility and power needed for success. For those requiring larger coverage areas, consider the Black Dog LED PhytoMAX-4 8S or the high-output PhytoMAX-4 12S.

FAQs

What is the Phyto-Genesis Spectrum?+

The Phyto-Genesis Spectrum is Black Dog LED's proprietary light blend that uses eight different LED colors. This spectrum is designed to maximize photosynthesis and trigger specific plant responses, such as increased terpene production and denser growth, compared to standard white or purple LEDs.

What is the difference between SP and SC models?+

The SP model uses a standard IEC power cord and is rated for 100-250V, making it perfect for most indoor grow environments. The SC model features a water-tight, locking power connection and is rated up to 277V, specifically designed for higher-humidity greenhouse applications.

Does the PhytoMAX-4 4S include UV light?+

Yes, the PhytoMAX-4 4S includes ultraviolet (UV) light. UV light is essential for building plant resistance to pests and pathogens while significantly increasing the production of secondary metabolites like terpenes and resins.

Is this light dimmable?+

Yes, this fixture is fully dimmable from 15% to 100% using a 0-10V controller. This allows you to reduce light intensity for seedlings or clones and ramp it up to full power during the flowering stage.

What is the expected lifespan of the LEDs and fans?+

Both the LEDs and the active cooling fans are rated for a Mean Time Before Failure (MTBF) of over 70,000 hours, ensuring years of reliable performance in your grow room.

What is the coverage area for the 4S model?+

The PhytoMAX-4 4S is ideal for small footprints. If you need coverage for a 2' x 2' or 3' x 3' area, this 250W light provides excellent intensity. For larger spaces, we recommend stepping up to the PhytoMAX-4 8S.
