Black Dog LED PhytoMAX-3 24SC Commercial LED Grow Light

The Black Dog PhytoMAX-3 24SC Commercial LED Grow Light is their most powerful and reliable LED plant grow light with unparalleled PAR levels for canopy penetration as well as spectacular plant yields. You'll enjoy unbeatable performance from Black Dog's proprietary full-cycle Phyto-Genesis Spectrum thanks to top-bin LEDs (350-750nm, UV to NIR PBAR) and with their generous warranty coverage there are no other LED lighting solutions like it.

Maximum Flowering Space - 8.75' x 8.75'
Up to 7+ pounds per light

The latest in grow lighting technology 

  • Increased Yields: Higher yields with lower energy costs equal more profit
  • Plant Specific Spectrum: The Phyto-Genesis Spectrum helps increase terpene production with the world's only true complete spectrum
  • Double The Coverage: The PhytoMAX-3 flowering footprint is double the industry standard, cover more area with fewer fixtures

Daisy Chainable

Being able to run up to 20 amps on one outlet means less infrastructure costs for you. 

Massive Flowering Footprint

PhytoMAX-3 24S has an impressive flowering coverage area of up to 8.75' x 8.75' per light.


Dimmable from 15% - 100% with industry-standard 0-10V dimming controllers.

Powerful Spectrum

3.4% ultraviolet (< 400nm) and 20% violet (400 - 450nm) light delivers impressive canopy penetration - Photon Flux Efficacy (PBAR 280 - 800nm): 2.15 μmol/J

Bigger Yields

Spectacular yield capabilities of up to 7+ pounds per light.

Better Coverage

Photon Flux Efficacy 2.15 μmol/J PBAR (280-800nm)
Total Photon Flux 2622 μmol/s PBAR

  • Minimum Vegetative Area: 6.0' x 6.0' (36 ft2)
  • Maximum Vegetative Area: 10.75' x 10.75' (120 ft2)
  • Minimum Flower Area: 5' x 5' (25 ft2)
  • Maximum Flower Area: 8.75' x 8.75' (77 ft2)

The Phyto-Genesis Spectrum

LED grow lights that offer UV and IR as part of their spectrum are popular, but the majority of them don't actually offer any significant level of UV output, unlike the PhytoMAX-3 24S.
The Black Dog Phyto-Genesis spectrum is the answer for your indoor garden plants. With 3.4% UV and 4.9 IR it will give you increased levels of desired compounds, which can lead to higher yields of 80 to 120+ gramms per sq ft - more than double industry standard!
