At 1220 actual watts and 2622 μmol/s total photon flux PBAR, the patented PhytoMAX-3 24SP LED grow lights are our most powerful grow lighting solution for all applications, with up to 7+ pounds of dried and cured  per light.

With PhytoMAX-3, we have delivered the most powerful and reliable, truly full-spectrum (350-750nm, UV to NIR PBAR) LED plant grow lights! The PhytoMAX-3 24SC uses only the highest-quality, latest-technology, top-bin LEDs to deliver Black Dog LED's proprietary full-cycle Phyto-Genesis Spectrum® evenly over the entire footprint, with unprecedented PAR levels, canopy penetration and yields!

NEW Features

  • Dimmable, from 15% - 100% with industry-standard 0-10V dimming controllers.
  • More Powerful Spectrum, 3.4% ultraviolet (< 400nm) and 20% violet (400 - 450nm) light provides better canopy penetration; Photon Flux Efficacy (PBAR 280 - 800nm): 2.13 μmol/J
  • Bigger Yields, Up to 7+ pounds per light

The Phyto-Genesis Spectrum

Don’t be fooled by the imitations with their limitations.
Many lighting companies claim to offer UV and IR in their spectrum. The fact of the matter is the vast majority of the grow lights on the market have completely insignificant UV output.

Go BEYOND PARTM with our Phyto-Genesis Spectrum. Our targeted spectrum with 3.4% UV and 4.9% IR give your plants increased  content (+26%) including minor like CBC, CBN, and Delta 8. Our spectrum also gives you increased yields at more than double the industry standard, with 80 to over 120 grams per square foot.
