Quick Overview

The PhytoMAX-3 16SH LED grow lights are 815 watts and 178 μmol/s total photobiological photon flux, perfect for small commercial spaces. They deliver full-spectrum plant grow lights with high-quality top-bin LEDs, delivering PAR levels, canopy penetration, and yields.


At 815 actual watts and 1748 μmol/s total photobiological photon flux (PBF), the patent-pending PhytoMAX-3 16SH LED grow lights are ideal for any large vegetative space, although it is an excellent as a flower production light with 2.75 to 5+ pounds of dried, cured, and trimmed flower per light.

With PhytoMAX-3, we have delivered the most powerful and reliable, truly full-spectrum (350-750nm, UV to NIR) plant grow lights! The PhytoMAX-3 16SH 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!

Bigger Flowering Footprint

PhytoMAX-3 16S has a larger area of coverage with up to 7.25' x 7.25' per light.


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): 2.14 μmol/J

Bigger Yields

2.75 to 5+ pounds per light

(Depending on strain, environment and growing skills)

Standard Power Inlet

IEC standard power inlet, allowing cords to be sourced worldwide.



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 cannabis targeted spectrum with 3.4% UV and 4.9% IR give your plants increased cannabinoid content (+26%) including minor cannabinoids like CBC, CBN, THCv, 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.
