Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for LED Products for Indoor Lighting
1 Scope
This document specifies the energy efficiency grades, minimum allowable values of energy efficiency, test methods, and implementation of the standard for LED downlights, directional integrated LED lamps, non-directional integrated LED lamps, LED high bay lamps, and retrofit double-capped LED lamps (hereinafter referred to as double-capped LED lamps) for general indoor lighting.
This document applies to the following products:
a) LED downlights that use LED as the light source, with a power supply voltage not exceeding AC 250 V, a beam angle ≥ 24°, and a shielding angle ≤ 40°. This does not include LED downlights that use integrated LED lamps, LED downlights with adjustable beam angle, or LED downlights with diffuser covers.
b) Directional integrated LED lamps in the PAR16, PAR20, PAR30, and PAR38 series with a power supply voltage of AC 220 V and lamp caps complying with the requirements for GU10, B22, E14, or E27.
c) Non-directional integrated LED lamps with a power supply voltage of AC 220 V, utilizing screw-type lamp caps conforming to GB/T 1406.1 or bayonet-type lamp caps conforming to GB/T 1406.5. This does not include non-directional integrated LED lamps with an external heat-dissipating optical lens design.
d) LED high bay lamps with a power supply voltage not exceeding 1000 V. This does not include LED high bay lamps that use integrated LED lamps.
e) Retrofit double-capped LED lamps with a power supply voltage of AC 220 V, a rated power ≤ 125 W, a nominal length ≤ 1500 mm, and a beam angle ≥ 120°.
For indoor lighting LED products with additional functions, only the lighting function shall be assessed.
This document does not apply to LED lighting products with non-white light, nor to LED lighting products where the rated correlated color temperature includes parts below 2700 K or above 6500 K.
