Specifically engineered for small or narrow grow layouts, this compact yet powerful member of the premium Zeus range features a linear multi-light bar configuration built on a slim, rigid aluminium chassis. Harnessing the latest top-bin diode breakthroughs from Samsung and Osram, it produces an impressive Photosynthetic Photon Flux (PPF) output of 965 µmol\/s while operating at an outstanding photon efficacy of 3.1 µmol\/s\/J. This advanced engineering yields intense light volume with minimal energy draw, making it a perfect tool for hobbyists and professionals who require uniform, single-source full-spectrum light without dangerous hot spots. Built for long-term commercial reliability, it boasts an incredible L90 rating, guaranteeing 90% of original photon output even after 60,000 hours of continuous operational service.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eBest For:\u003c\/strong\u003e Linear 1.2m x 0.6m canopy cultivation, narrow rectangular grow environments, vegetative staging, mother plant isolation, and space-restricted vertical multi-layer rack arrays.\u003c\/p\u003e\n\u003ch3\u003eKey Features \u0026amp; Technical Advancements\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Performance Samsung \u0026amp; Osram Chips:\u003c\/strong\u003e Utilizes premium, top-bin diodes to deliver a perfectly balanced full spectrum designed to fuel rapid crop transitions from vegetative growth through heavy flower development.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElite 3.1 µmol\/s\/J Efficacy \u0026amp; L90 Lifecycle:\u003c\/strong\u003e Maximizes electrical conversion efficiency while maintaining 90% light intensity at 60,000 hours, ensuring long-term commercial return on investment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced Clear Glue Protection Cover:\u003c\/strong\u003e LED bars are engineered with proprietary Clear Glue shielding technology, providing a highly moisture-resistant barrier that protects components without dropping photon transmissivity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModular Replacement Magnet Bars:\u003c\/strong\u003e Features replaceable 100W Pro 3.1 magnetic light bars that lock into place easily, offering effortless plug-and-play assembly and future-proof spectrum customization.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDetachable Smart Driver \u0026amp; Dimming:\u003c\/strong\u003e Equipped with a high-quality, fully dimmable Lumatek driver that can be unmounted and mounted remotely outside the cultivation area to reduce internal ambient heat loads.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Technical Specifications Matrix\u003c\/h3\u003e\n\u003ctable style=\"border-collapse: collapse; width: 100%; text-align: left;\" cellpadding=\"5\" border=\"1\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #f2f2f2;\"\u003e\n\u003cth\u003eSpecification Parameters\u003c\/th\u003e\n\u003cth\u003eEngineering Metric \/ Detail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand \u0026amp; Series\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLumatek Zeus Pro (Edition 3.1)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePower Consumption\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e300 Watts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePhotosynthetic Photon Flux (PPF)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e965 µmol\/s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFixture Photon Efficacy\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3.1 µmol\/s\/J\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOptimal Coverage Footprint\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.2m x 0.6m (Full-Cycle Staging)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePhysical Unit Dimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1180mm (W) x 491mm (D) x 70mm (H)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDiode Longevity Rating\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eL90 (90% Output Retention at 60,000 Hours)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eExternal System Control\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLumatek Control Panel Plus 2.0 or universal 0-10V controller link\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCommercial Warranty\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5-Year Manufacturer Warranty Protection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eNursery Layout \u0026amp; Environmental Optimization Tips\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure \u0026amp; Support Rigging Setup:\u003c\/strong\u003e The narrow 1180mm x 491mm footprint of this 300W fixture is an ideal linear match for narrow rectangular enclosures like the **SeaHawk Grow Tent 145R or 145RH**.
