Details about the MEAN WELL HLG-120H-12B
The MEAN WELL HLG-120H-12B is a high-performance 120W LED driver engineered for advanced light control and maximum environmental resilience. As a "B-Type" model, it is distinguished by its integrated 3-in-1 dimming functionality. This allows users to seamlessly adjust light output using a 1–10V DC signal, a 10V PWM signal, or an external resistance, making it an ideal choice for automated smart lighting systems.
Built for extreme durability, the HLG-120H-12B features a fully potted metal housing with an IP67 rating. This ensures the internal electronics are completely sealed against dust and remain protected even during temporary immersion in water. Such robust construction is essential for high-exposure outdoor projects, industrial facilities with high moisture levels, and professional architectural installations.
The unit operates with a dual-mode constant voltage and constant current output, providing 92% efficiency and active Power Factor Correction (PFC). Its fanless design utilizes natural air convection for cooling, ensuring silent operation and a typical lifespan of over 62,000 hours, even at case temperatures up to +80 °C. Backed by a premier 7-year manufacturer warranty, the HLG-120H-12B is a top-tier solution for dimmable street lamps, industrial high-bay lighting, and large-scale horticultural systems.
