Quick Overview

PhytoMAX-3 8SP LED grow lights provide a full spectrum of light so they are perfect for small commercial spaces or cloning areas. They are reliable and provide high PAR levels and canopy penetration, so they can produce high yields.



At 410 actual watts and 874 μmol/s total photobiological photon flux (PBF), the patent-pending PhytoMAX-3 8SP LED grow lights are ideal for any commercial vegetative or cloning space, although it will still hold its own as a production light with 5 to 12+ ounces 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 8SP 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!

Daisy Chain Compatible

Running multiple lights on one outlet means less infrastructure- up to 20 amps on one outlet.

Bigger Flowering Footprint

PhytoMAX-3 8S has a larger area of coverage with up to 5.0' x 5.0' 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): 2.13 μmol/J

Bigger Yields

1.3 to 2.5+ pounds per light

(Depending on strain, environment and growing skills)



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.
