The YR-FL340 Series high power LED floodlighting systems are ruggedly constructed to deliver an unprecedented combination of performance and reliability in high-intensity applications. Designed to address the critical concern in high power LED lighting, YR-FL340 features a large form factor cast aluminum heat sink that offers more surface area than other products in its class to dissipate the huge amount of heat generated during high current density operations. Superior thermal dissipation performance ensures the LED light sources have a lumen maintenance greater than 70% after 50,000 hours of operation (L70) while maintaining excellent color consistency. Modular configuration of YR-FL340 lighting systems adds application scalability and field maintainability. Utilizing high power Samsung 3030 LED packages and high reliability Mean Well LED drivers, YR-FL340 achieves a highly competitive system efficacy at 110 lumens per watt. The accurate and flexible optics packages create uniform photometric distribution across large areas. The electrical components and LED engines are enclosed at rated IP66 for wet locations and outdoor weatherproof operation.
