In June 2022, the Hong Kong Electrical and Mechanical Services Department issued a consultation document on the revision of the "Code of Practice for Energy Labeling of Products" for the fourth phase of the mandatory energy efficiency labeling scheme, The document states that the revised fifth edition of the "Code of Practice on Energy Labeling of Products" will come into effect in the second quarter of 2023, the fifth revision will add energy efficiency labeling requirements for light-emitting diode (LED) lamps.

The detailed technical requirements for Light Emitting Diode (LED) Lamps in this regulation are as follows:

15、Energy Efficiency Labelling for Lighting Emitting Diode Lamp.

15.1、Scope.

15.1.1、Clause 15 of the Code, unless the Director provides otherwise, applies to a lighting emitting diode (LED) lamp defined in the ordinance, that is, the products specified in clauses 15.1.2 and 15.1.3.

15.1.2、“Lighting emitting diode lamp”, subject to clause 15.1.3 of the Code, means a product –

(a) that is a type of directional or non-directional lighting emitting diode lamp which has a single lamp cap;

(b) that is of integrated type;

(i) uses mains electricity as the only power source; and

(ii) has a rated lamp wattage up to 60 watts, whether or not having a dimming feature.

15.1.3、“Lighting emitting diode lamp” does not include –

(a) lighting emitting diode tubes;

(b) lighting emitting diode lamps that solely produce tinted or coloured light; or

15.3、Tests Required to be Carried Out.

The tests specified in this clause are required to be carried out, in accordance with IEC 62612 or other equivalent international standards approved by the Director, in order to find out the energy efficiency and performance characteristics of a light emitting diode lamp. A test report required to be submitted to the Director under section 6 of the ordinance shall contain the results of these tests:

(a) Measurement of luminous flux (initial);

(b) Measurement of power consumption (initial);

15.4.2、Family Grouping.

(d) For LED lamps of the same characteristics but with different colour temperatures, they shall be tested individually as their energy efficiency performances are different. For LED lamps with the same energy efficiency and performance characteristics (including colour temperature), but with different lamp caps, they may be treated as belonging to the same family of models and adopt the same test report.

15.5、Energy Efficiency Grading.

15.5.1、The energy efficiency grading of an LED lamp shall be determined as shown in Table 15.1, with Grade 1 having the best performance and Grade 5 having the worst performance.

15.5.2、In order to determine the energy efficiency grading according to clause 15.5.3 of the Code, the measured luminous efficacy (Em) obtained in clause 15.4 of the Code shall be compared with the following rated luminous efficacy (Er) which is determined and calculated based on the rated luminous flux and the rated wattage of the same product model –

The energy efficiency grading is determined by using the measured lamp luminous efficacy (Em) or the rated lamp luminous efficacy (Er), whichever is smaller.

Table 15.1 – Derivation of Energy Efficiency Grades.

Note: X = measured lamp luminous efficacy (Em) or the rated lamp luminous efficacy (Er), whichever is smaller.

15.5.3、The aforesaid measured luminous efficacy refers to the average values (both luminous flux and power consumption) measured after stabilisation of the LED lamp.

15.5.4、The aforesaid lumen maintenance refers to the average value measured after stabilisation of the LED lamp.
