YR-HB220 Series (50W/80W/100W/120W/150W/200W) LED high bay lights from Yaorong Technology are affordable, reliable LED lighting solutions designed to replace up to 600 watt metal halide and high pressure sodium fixtures. Engineered to provide dependable performance and remarkable energy savings in warehouses, manufacturing facilities, gyms, garages, general task areas, and many other industrial, applications, YR-HB220 Series deliver up to 22,000 lumens of high quality light while drawing only 200 watts. A rock solid heat dissipating design in conjunction with OSRAM 3030 SMD LED technology allows the luminaire to last substantially longer than the rated 50,000 hours. The high performance LEDs are mounted to an aluminum heat sink which works with heat pipes to ensure proper thermal management of the system. The combination of thermal conduction and radiation technology will help to sustain maximum light, life and color consistency. A high efficiency Mean Well driver operates within a wide 100-277 VAC range and provides accurate constant current control. YR-HB220 Series utilizes anodized aluminum reflectors to narrow the beam angle to 60 or 90 degrees. Optional PC refractors are available. These lights are ETL, DLC, SAA, C-Tick, CE and RoHS certified to meet U.S. and international safety standards and are qualified for utility rebates, tax credits and energy loan programs in some markets.
