Producing 1,594 µmol\/s of total PBAR output, it is designed as a direct lighting replacement for traditional 1000W HPS fixtures while drawing substantially less power.\u003c\/p\u003e\n\u003cp\u003eAt the center of the PhytoMAX-4 12S is Black Dog LED's Phyto Genesis Spectrum, which uses eight LED colors spanning ultraviolet, visible PAR wavelengths, and infrared. Rather than optimizing the fixture around PAR output alone, Black Dog designed the spectrum to influence both photosynthesis and photomorphogenic plant responses throughout the growing cycle.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eVeg Footprint: 4.25' x 4.25'\u003c\/li\u003e\n\u003cli\u003eFlower Footprint: 3.5' x 3.5'\u003c\/li\u003e\n\u003cli\u003eWatts: 750W\u003c\/li\u003e\n\u003cli\u003eSpectrum: Full Spectrum\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 12S combines this specialized spectrum with 15% to 100% dimming, active LED cooling, 336 LEDs, multiple voltage configurations, and a rated mean time before failure exceeding 70,000 hours.\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\u003eTotal PBAR output from 280 to 800 nm is rated at 1,594 µmol\/s, consisting of:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUV (280–400 nm):\u003c\/strong\u003e 47 µmol\/s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePAR (400–700 nm):\u003c\/strong\u003e 1,428 µmol\/s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIR (700–800 nm):\u003c\/strong\u003e 119 µmol\/s\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis approach provides ultraviolet and far red wavelengths directly from the primary fixture rather than relying 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. Black Dog incorporates UV throughout the fixture so it is distributed across the illuminated growing area rather than being concentrated in separate UV bars.\u003c\/p\u003e\n\u003cp\u003eUV wavelengths can trigger photomorphogenic responses in plants and are included by Black Dog to encourage compact growth, 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 it separately within the fixture's broader 280 to 800 nm 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 the 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 to encourage tighter plant structure and improved canopy penetration.\u003c\/p\u003e\n\u003ch3\u003eGreen and Yellow Light\u003c\/h3\u003e\n\u003cp\u003eBroad spectrum white LEDs provide wavelengths throughout the green and yellow portion of the spectrum from approximately 480 to 600 nm.\u003c\/p\u003e\n\u003cp\u003eThese wavelengths contribute to photosynthesis while also providing more natural visual illumination, making it easier to inspect plant color and overall condition under the fixture.\u003c\/p\u003e\n\u003cp\u003eBlack Dog intentionally 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\u003c\/h3\u003e\n\u003cp\u003eRed wavelengths from approximately 600 to 700 nm provide a major contribution to photosynthesis. The Phyto Genesis Spectrum incorporates two distinct red peaks, balanced against blue light to help control excessive stem elongation.\u003c\/p\u003e\n\u003cp\u003eFar red wavelengths between approximately 700 and 750 nm extend the spectrum beyond conventional PAR. These wavelengths can contribute to photosynthetic efficiency through interactions commonly associated with the Emerson Effect.\u003c\/p\u003e\n\u003cp\u003eThe result is a spectrum that extends from ultraviolet through visible wavelengths and into far red rather than ending at the traditional PAR boundaries.\u003c\/p\u003e\n\u003ch3\u003e1,594 µmol\/s From 750 Watts\u003c\/h3\u003e\n\u003cp\u003eThe PhytoMAX-4 12S produces 1,594 µmol\/s of PBAR output while consuming 750 watts.\u003c\/p\u003e\n\u003cp\u003eBlack Dog positions the 12S as a drop in lighting replacement for traditional 1000W HPS fixtures, providing high photon output while reducing fixture power consumption by approximately 250 watts compared with a 1000W HPS lamp.\u003c\/p\u003e\n\u003cp\u003eThe fixture is designed for a vegetative footprint of approximately 4.25' x 4.25' and a flowering footprint of approximately 3.5' x 3.5'.\u003c\/p\u003e\n\u003ch3\u003e15% to 100% Dimming\u003c\/h3\u003e\n\u003cp\u003eThe PhytoMAX-4 12S supports industry standard 0 to 10V dimming and can be adjusted from approximately 15% through 100% output.\u003c\/p\u003e\n\u003cp\u003eThis gives growers the ability to reduce intensity for younger plants, acclimation periods, or lower light requirements, then increase output 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\u003ePhytoMAX-4 uses active cooling to manage LED operating temperatures. Keeping LEDs cooler can improve operating efficiency and help preserve output over the fixture's service life, particularly for specialized ultraviolet and violet LEDs.\u003c\/p\u003e\n\u003cp\u003eThe cooling system incorporates multiple redundant fans so cooling is not dependent on a single fan.\u003c\/p\u003e\n\u003cp\u003eBlack Dog rates both the fans and the fixture's mean time before failure at more than 70,000 hours.\u003c\/p\u003e\n\u003ch3\u003eCompact High Output Design\u003c\/h3\u003e\n\u003cp\u003eDespite its 750W power draw and 1,594 µmol\/s PBAR output, the PhytoMAX-4 12S measures only 15\" x 15\" x 4.5\".\u003c\/p\u003e\n\u003cp\u003eThe fixture weighs 28 lb, making proper overhead mounting important. A pair of V hooks and ratcheting rope hangers are included for installation.\u003c\/p\u003e\n\u003cp\u003eThe compact fixture format can also simplify replacing existing HID fixtures where available overhead space is limited.\u003c\/p\u003e\n\u003ch3\u003eSP vs SC Models\u003c\/h3\u003e\n\u003cp\u003eThe PhytoMAX-4 12S is available in SP and SC configurations. Light output, spectrum, power consumption, dimensions, and core lighting performance remain the same.
