Physical Characteristics: - Color: White - Density: 3.1Mg/m^3 - Porosity: 22% - Flexural strength: 170Mpa - Coefficient of thermal expansion: 7.9×10^-6--/С (200～500℃) 9×10^-6/С (200～1000℃)

The YB-WPL-2 Series Full cut off LED wall pack light from Yibai is high-performance wall-mounted luminaires with a slim cut-off body. Engineered to create safe, brightly lit outdoor environments in parking garages and building exteriors with minimal energy consumption and maintenance, YB-WPL-2 Series Full cut off LED wall pack light delivers superior value in a low-profile, architectural style design. Superior thermal management is accomplished through a rugged die-cast aluminum housing with an effective heat sinking design. Samsung SMD3030 LEDs are mounted metal core PCBs which is thermally interfaced to the heat sink for efficient heat transfer. Advanced thermal control maximizes the reliability and lifespan of the LED light engine which delivers years of dependable performance with excellent efficacies and lumen outputs.
