Introducing the 1050W GH Top Light LED (Red + Blue), the latest addition to Lumatek’s commercial greenhouse lighting range. As the most powerful unit in the lineup, this advanced fixture delivers an exceptional photon efficacy of 3.5 μmol/J and a total PPF output of 3675 μmol/s, making it ideal for professional growers seeking maximum efficiency and light intensity in large-scale operations.
This high-output LED top light is specifically engineered for flowering crops that require high PPFD levels. It is tailored for industrial-scale growers who demand robust, reliable lighting that enhances plant development and optimizes yield. When compared to traditional 1000W HPS units, the 1050W GH Top Light provides double the light levels with a more balanced, finely tuned Red + Blue spectrum. In fact, it matches the output of two 1000W HPS fixtures while delivering superior spectral quality for healthier, more productive crops.
Designed with both innovation and efficiency in mind, the fixture features a slim and compact form factor with passive thermal management. Precision-crafted gaps between the cooling fins promote convective airflow, ensuring efficient heat dissipation without the need for active cooling systems. This design guarantees low maintenance, exceptional longevity with an L90 rating of over 50,000 hours, and consistent world-class performance even under demanding conditions.
Built with only the highest-grade components, the 1050W GH Top Light LED is IP65-rated for protection against water and dust, making it perfectly suited for greenhouse environments. The unit supports external dimming from 20% to 100% and is compatible with Lumatek and universal 0–10V controllers, offering seamless integration into existing control systems. Daisy chain capability adds further convenience for scalable installations.
Weighing 13 kg and measuring 730 x 325 x 112 mm, this fixture delivers uniform light distribution with a wide 120° beam angle. It operates efficiently across a wide voltage range (208–400V AC, 50–60Hz), drawing 1061W at 230V AC or 1054W at 400V AC. The power factor exceeds 0.98 for both voltage options, reflecting its energy-efficient design. With a 3-year warranty and compliance with CE, EMC, LVD, and key industry standards including IEC 60598-1/-2-1, EN IEC 62031-2, EN 62471, and EN 62493, this fixture represents a dependable, high-performance lighting solution for year-round greenhouse cultivation.
