Designed for large indoor growing areas that require substantial intensity and canopy penetration, the 24S combines Black Dog LED's eight color Phyto Genesis Spectrum with integrated ultraviolet, visible PAR wavelengths, infrared, active cooling, and precise 0 to 10V dimming.\u003c\/p\u003e\n\u003cp\u003eRather than measuring performance only within the conventional 400 to 700 nm PAR range, Black Dog evaluates the fixture across a broader 280 to 800 nm photobiologically active range. This allows the PhytoMAX-4 24S to deliver ultraviolet and far red wavelengths alongside its primary photosynthetic output.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eVeg Footprint: 6' x 6'\u003c\/li\u003e\n\u003cli\u003eFlower Footprint: 5' x 5'\u003c\/li\u003e\n\u003cli\u003eWatts: 1500W\u003c\/li\u003e\n\u003cli\u003eSpectrum: Full Spectrum\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWith 672 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 24S is built for growers who need the highest output available within the PhytoMAX-4 family.\u003c\/p\u003e\n\u003ch3\u003ePhyto Genesis Spectrum\u003c\/h3\u003e\n\u003cp\u003eBlack Dog LED's Phyto Genesis Spectrum incorporates eight LED colors spanning ultraviolet, visible light, and infrared wavelengths.\u003c\/p\u003e\n\u003cp\u003eThe PhytoMAX-4 24S produces 3,187 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 94 µmol\/s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePAR (400–700 nm):\u003c\/strong\u003e 2,856 µmol\/s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIR (700–800 nm):\u003c\/strong\u003e 237 µmol\/s\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis broad spectral approach incorporates ultraviolet and far red wavelengths directly into the primary fixture instead of depending on 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 so ultraviolet wavelengths reach the illuminated growing area alongside the rest of the spectrum rather than being concentrated through separate UV bars.\u003c\/p\u003e\n\u003cp\u003eUV wavelengths can influence photomorphogenic responses associated with plant structure, pigmentation, and natural defense mechanisms.\u003c\/p\u003e\n\u003cp\u003eBecause ultraviolet sits outside the conventional 400 to 700 nm PAR range, Black Dog reports its output independently as part of 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.\u003c\/p\u003e\n\u003cp\u003eViolet 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 to chlorophyll driven photosynthesis and also influence plant morphology.
