Who This Is For

  • You are upgrading to high-intensity LED because your current HPS setup generates too much heat to keep a stable canopy.
  • You are scaling up your footprint because your smaller fixtures cannot deliver the light penetration needed for yield.
  • You are choosing the SC model because your greenhouse environment requires water-tight power locks to prevent shorts.

What We Found

  • The active cooling fans are quiet enough that you can actually hear yourself think while working in the room.
  • We suggest the SC model for greenhouses because the locking power cord stays put during heavy cleaning.
  • The 45-pound weight is significant, so we tell buyers to double-check their rack ratings before hanging.

What Users Say

  • Facilities that replaced DE HPS lights say their cooling costs dropped enough to pay for the upgrade in a year.
  • Operators who switched to this spectrum report more consistent resin quality across their entire harvest.

Black Dog LED PhytoMAX-4 20S Full Spectrum LED Grow Light

Scaling up your indoor garden requires more than just power; it requires precision. The Black Dog LED PhytoMAX-4 20S is engineered for professional-grade results, delivering a massive 2657 µmol/s to ensure your plants thrive in large-scale environments. Using 1250 watts of high-efficiency power, this fixture outperforms traditional DE HPS lights while maintaining lower operating costs. With the proprietary Phyto-Genesis Spectrum®, you get a complete light profile that triggers optimal plant responses from seed to harvest. If you need even more power for larger commercial footprints, consider the Black Dog LED PhytoMAX-4 24S, or for slightly smaller setups, the PhytoMAX-4 16S offers the same high-efficiency technology.
