National Standard of the P.R.C., Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades of LED Flat Panel Luminaires (6 page(s), in Chinese)

This standard specifies the energy efficiency grade, energy efficiency limit value and test methods of LED flat panel luminaires. This standard is applicable to LED flat panel luminaires for common lighting with LED as light source, with rated voltage 220V, frequency 50Hz, thickness not exceeding 85mm, including LED light source and its control devices. The thickness of external control device is not calculated in the thickness of lamps. This standard is not applicable to LED flat panel luminaires with energy-consuming non-illumination additional function, LED flat panel luminaires with dimming/coloring adjustment function, or LED flat panel luminaires with color, pattern or decoration on continuous luminous surface.
