Producing 2,656 µmol\/s of total PBAR output, the 20S combines substantial photon output with Black Dog LED's eight color Phyto Genesis Spectrum, integrated ultraviolet and infrared wavelengths, active cooling, and precise 0 to 10V dimming.\u003c\/p\u003e\n\u003cp\u003eThe PhytoMAX-4 20S is designed around more than conventional PAR performance. Its spectrum extends from 280 to 800 nm, incorporating ultraviolet, visible PAR wavelengths, and infrared to influence both photosynthesis and photomorphogenic plant responses throughout the growing cycle.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eVeg Footprint: 5.5' x 5.5'\u003c\/li\u003e\n\u003cli\u003eFlower Footprint: 4.5' x 4.5'\u003c\/li\u003e\n\u003cli\u003eWatts: 1250W\u003c\/li\u003e\n\u003cli\u003eSpectrum: Full Spectrum\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWith 560 LEDs, a compact 19\" x 19\" housing, 15% to 100% dimming, multiple voltage configurations, and a rated mean time before failure exceeding 70,000 hours, the 20S is designed for growers who need high intensity lighting across a larger canopy.\u003c\/p\u003e\n\u003ch3\u003ePhyto Genesis Spectrum\u003c\/h3\u003e\n\u003cp\u003eBlack Dog LED's Phyto Genesis Spectrum combines eight LED colors to provide plants with wavelengths extending beyond the conventional 400 to 700 nm PAR range.\u003c\/p\u003e\n\u003cp\u003eThe PhytoMAX-4 20S produces 2,656 µmol\/s of total PBAR output from 280 to 800 nm, consisting of:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUV (280–400 nm):\u003c\/strong\u003e 78 µmol\/s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePAR (400–700 nm):\u003c\/strong\u003e 2,380 µmol\/s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIR (700–800 nm):\u003c\/strong\u003e 198 µmol\/s\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis approach integrates ultraviolet and far red wavelengths directly into the primary fixture rather than requiring separate supplemental lighting.\u003c\/p\u003e\n\u003ch3\u003eIntegrated Ultraviolet\u003c\/h3\u003e\n\u003cp\u003eApproximately 3% of the Phyto Genesis Spectrum is ultraviolet light below 400 nm.\u003c\/p\u003e\n\u003cp\u003eBlack Dog distributes UV throughout the fixture, providing ultraviolet exposure across the illuminated growing area rather than concentrating it through separate supplemental UV bars.\u003c\/p\u003e\n\u003cp\u003eUV wavelengths can trigger several photomorphogenic responses in plants. Black Dog incorporates this portion of the spectrum to encourage compact plant structure, pigmentation, and natural plant defense responses.\u003c\/p\u003e\n\u003cp\u003eBecause UV falls outside the conventional 400 to 700 nm PAR range, Black Dog reports its output separately within the fixture's broader PBAR measurement.\u003c\/p\u003e\n\u003ch3\u003eViolet and Blue Light\u003c\/h3\u003e\n\u003cp\u003eThe Phyto Genesis Spectrum incorporates two violet wavelengths within the 400 to 450 nm range. Violet light can penetrate dense plant canopies and provide useful light deeper within plant structure.\u003c\/p\u003e\n\u003cp\u003eBlue wavelengths from approximately 450 to 480 nm contribute strongly to chlorophyll driven photosynthesis while also influencing plant morphology. Black Dog balances these wavelengths with the rest of the spectrum to encourage tighter plant structure and improved canopy penetration.\u003c\/p\u003e\n\u003ch3\u003eGreen and Yellow Light\u003c\/h3\u003e\n\u003cp\u003eGreen and yellow wavelengths from approximately 480 to 600 nm are supplied through broad spectrum white LEDs.\u003c\/p\u003e\n\u003cp\u003eThese wavelengths contribute to photosynthesis while providing more natural visual illumination, making plant color and condition easier to inspect beneath the fixture.\u003c\/p\u003e\n\u003cp\u003eBlack Dog balances this portion of the spectrum against its blue and red output rather than relying primarily on broad spectrum white LEDs.\u003c\/p\u003e\n\u003ch3\u003eRed and Far Red Light\u003c\/h3\u003e\n\u003cp\u003eRed wavelengths from approximately 600 to 700 nm make a major contribution to photosynthesis. The Phyto Genesis Spectrum incorporates two red peaks and balances them with blue wavelengths to help control excessive stem elongation.\u003c\/p\u003e\n\u003cp\u003eFar red wavelengths extending beyond 700 nm can contribute to photosynthetic efficiency through interactions associated with the Emerson Effect.\u003c\/p\u003e\n\u003cp\u003eTogether, these wavelengths give the PhytoMAX-4 20S spectral output extending from ultraviolet through the visible range and into far red.\u003c\/p\u003e\n\u003ch3\u003e2,656 µmol\/s From 1250 Watts\u003c\/h3\u003e\n\u003cp\u003eThe PhytoMAX-4 20S produces 2,656 µmol\/s of PBAR output while drawing 1250 watts.\u003c\/p\u003e\n\u003cp\u003eIts high total output is designed for larger growing areas where substantial intensity and canopy penetration are required.\u003c\/p\u003e\n\u003cp\u003eThe fixture is rated for a vegetative footprint of approximately 5.5' x 5.5' and a flowering footprint of approximately 4.5' x 4.5'.\u003c\/p\u003e\n\u003ch3\u003e15% to 100% Dimming\u003c\/h3\u003e\n\u003cp\u003eThe PhytoMAX-4 20S supports industry standard 0 to 10V dimming and can be adjusted from approximately 15% through 100% output.\u003c\/p\u003e\n\u003cp\u003eThis wide adjustment range allows light intensity to be reduced for young plants, acclimation periods, or lower intensity applications and progressively increased as the canopy develops.\u003c\/p\u003e\n\u003cp\u003eA compatible 0 to 10V dimming controller is required for external dimming control.\u003c\/p\u003e\n\u003ch3\u003eActive LED Cooling\u003c\/h3\u003e\n\u003cp\u003eThe PhytoMAX-4 20S uses active cooling to manage operating temperatures across its 560 LEDs.\u003c\/p\u003e\n\u003cp\u003eKeeping LEDs cooler can help maintain efficiency and support longer component life, particularly for the specialized ultraviolet and violet LEDs incorporated into the Phyto Genesis Spectrum.\u003c\/p\u003e\n\u003cp\u003eBlack Dog uses multiple redundant cooling fans rather than depending on a single fan for thermal management.\u003c\/p\u003e\n\u003cp\u003eExpected fan life is rated at more than 70,000 hours, matching the fixture's stated mean time before failure.\u003c\/p\u003e\n\u003ch3\u003eCompact High Output Construction\u003c\/h3\u003e\n\u003cp\u003eDespite its 1250W power draw and 2,656 µmol\/s PBAR output, the PhytoMAX-4 20S measures only 19\" x 19\" x 4.5\".\u003c\/p\u003e\n\u003cp\u003eThe fixture weighs 45 lb, so mounting hardware and overhead support should be appropriately rated for its installed weight.\u003c\/p\u003e\n\u003cp\u003eBlack Dog includes a pair of V hooks and ratcheting rope hangers with the fixture for installation.\u003c\/p\u003e\n\u003ch3\u003eSP vs SC Models\u003c\/h3\u003e\n\u003cp\u003eThe PhytoMAX-4 20S is available in SP and SC configurations.\u003c\/p\u003e\n\u003cp\u003eBoth versions provide the same spectrum, wattage, photon output, dimensions, and core lighting performance.
