1 Scope

China's mandatory energy efficiency standard for fluorescent lamps used in general lighting - the tubes and compact lamps that lit offices, schools, factories and homes for a generation, and which this standard has progressively squeezed out of the market as LED sources overtook them. It specifies the minimum allowable values of energy efficiency, the energy conservation evaluation values, the energy efficiency grades, the test methods and the inspection rules for fluorescent lamps for general lighting. The efficiency is expressed as the initial luminous efficacy in lumens per watt, tabulated by lamp type, rated power and correlated colour temperature - the last of these mattering because a warmer lamp is inherently less efficacious than a cooler one and would otherwise be judged unfairly against it. The minimum allowable value is the compliance threshold below which a lamp may not be manufactured, imported or sold; the energy conservation evaluation value is the higher threshold used for the energy saving certification; and the grades are what the purchaser reads on the energy label. What gives a standard of this kind its force is that it is not a target but a floor, revised upward each edition: each revision removes the least efficient products from the market outright, and it is that ratchet rather than any subsidy that has done most to change what is actually sold. The test methods refer the measurement of efficacy, and the lamp life and lumen maintenance that go with it, back to the product standards, so that the label figure and the compliance figure are obtained in the same way. Issued on 29 December 2022 and in force since 1 January 2024, it replaces GB 19044-2013.

This document specifies the energy efficiency grades, minimum allowable values and test methods of fluorescent lamps for general lighting. This document applies to the following types of fluorescent lamps: -- Self-ballasted fluorescent lamps with a rated power of 3 W ~ 60 W and self- ballasted electrodeless fluorescent lamps with a rated power of 10 W ~ 60 W, both of which are of rated voltage 220 V, frequency

50 Hz AC power supply, using screw lamp cap or bayonet lamp cap, integrating control, start and stable ignition components. -- Preheated cathode lamps (hereinafter referred to as double-capped fluorescent lamps) that work on lines with starters at AC power frequency and can work on high-frequency lines, and work on high-frequency lines; -- Single-capped fluorescent lamps with preheated cathodes; -- Single-ended electrodeless fluorescent lamps of rated power 30 W ~ 400 W. This document does not apply to self-ballasted fluorescent lamps with shades.
