The fourth phase of mandatory energy labeling in Hong Kong, with the addition of LED lights, will be implemented from September 1, 2023 and will be fully implemented on December 1, 2024!

 

In September 2023, the Hong Kong Department of Electrical and Mechanical Services released the fourth phase of the mandatory energy efficiency labeling program, the Code of Practice for Product Energy Labeling. The program includes products such as air conditioners, refrigerators, compact fluorescent lamps (CFL), washing machines, dehumidifiers, televisions, storage water heaters, induction cookers, LED lights, gas cooking stoves, and instant gas water heaters.


The fourth phase of Hong Kong's mandatory energy efficiency labeling program includes three new products: LED lights, gas cooking stoves, and instant gas water heaters, which will be implemented on September 1, 2023, with a 15 month transition period and will be fully implemented on December 1, 2024. The energy label divides the energy efficiency of the same type of product into five levels, with the first level indicating the highest energy efficiency and the fifth level indicating the lowest energy efficiency. Since its launch, the mandatory labeling program has seen an increasing number of energy-efficient product models on the market, providing consumers with more choices.

 

 

The detailed technical requirements for LED bulbs in this regulation are as follows:

15. Energy efficiency label for light-emitting diode (LED) lights

15.1 Scope

15.1.1. Unless otherwise specified by the Director, paragraph 15 of the Code applies to LED lights as defined in the Regulations (i.e. products specified in paragraph 15.1.2)
15.1.2 LED lights refer to lights that comply with the following instructions——
(a) Using light-emitting diode technology (but not organic light-emitting diode technology) to emit light; and
(b) This lamp——
(i) Can provide general lighting;
(ii) Using mains power as the sole light source; and
(iii) Rated wattage value does not exceed 60W

 

15.3 Required tests

The tests specified in this paragraph must be conducted in accordance with IEC62612 or other equivalent international standards approved by the Director to verify the energy efficiency and functional characteristics of LED lights. According to Article 6 of the Regulations, the test report required to be submitted to the Director shall reflect the results of the following tests:
(a) Measure luminous flux (initial value);
(b) Measure power consumption (initial value);
(c) Measure standby power consumption (initial value);
(d) Measurement of color rendering index (initial value and value at the end of 6000 hours)
(e) Measure color consistency (initial value and value at the end of 6000 hours)
(f) Measure displacement factor (initial value);
(g) Measure the number of switch cycles;
(h) Test the lumen maintenance rate after 6000 hours; as well as
(i) Test the survival rate after 6000 hours.

 

15.4.2 Division of Test Series

(d) If multiple LED lights have the same characteristics but different color temperatures, they must be tested separately due to their different energy efficiency. If multiple light-emitting diode lights have the same energy efficiency and functional characteristics (including color temperature), but have different lamp heads, they can be considered as the same model series and can use the same test report.

 

15.5 Energy Efficiency Rating

15.5.1 The energy efficiency level of light-emitting diode lamps shall be determined according to Table 15.1, with the first level performing the best and the fifth level performing the worst.

15.5.2. The energy efficiency level should be determined according to paragraph 15.5.3 of the code. The measured luminous efficiency (Em) obtained in paragraph 15.4 of the code must be compared with the rated luminous efficiency (Er), which is determined based on the rated luminous flux and rated wattage of the same product model——

The energy efficiency level is determined using the measured luminous efficiency (Em) or rated luminous efficiency (Er) of the electric lamp, whichever is lower.

 

15.5.3 The above measured luminous efficiency refers to the average value (including luminous flux and power consumption) measured by the light-emitting diode lamp at the end of its stable period.

15.5.4 The lumen maintenance rate measured above refers to the average value measured by the LED lamp at the end of its stability period.

15.5.5 Unless otherwise instructed, the provisions of the code apply to light-emitting diode lights that operate at maximum power without adjustable dimming and/or light-emitting diode lights with adjustable colors.

 

15.6 Relevant regulations

15.6.1 In the test report submitted to the Director in accordance with Article 6 of the Regulation, the results of the test conducted in accordance with CIE84, IEC62612, IEC62301 or other equivalent international standards approved by the Director must show that the relevant model of light-emitting diode lamp meets the following performance requirements:

(e) The chromaticity distribution (initial value and value at the end of 6000 hours) measured by each individual tested LED lamp in the sample must be maintained within a 6th order Mac Adam ellipse.
(f) If the rated power exceeds 2 watts and is less than or equal to 5 watts, the average displacement factor shall not be less than 0.4; If the rated power exceeds 5 watts and is less than or equal to 25 watts, the average displacement factor shall not be less than 0.7; If the rated power exceeds 25 watts, the average displacement factor shall not be less than 0.9.
(g) For light-emitting diode lamps with a rated lifespan exceeding or equal to 30000 hours, each individually tested light-emitting diode lamp must have a switching cycle of more than or equal to 15000 times. For LED lights with a rated lifespan of less than 30000 hours, the number of switching cycles for each individually tested LED light must exceed or equal to half of the rated lifespan (in hours).
(h) The average lumen maintenance rate measured after 6000 hours shall not be less than 80%.
(i) The survival rate of the electric lamp measured after 6000 hours shall not be less than 90%.

15.6.2 The rated power consumption, rated luminous flux, rated chromaticity coordinates, rated color rendering index, rated displacement factor, and rated lamp life claimed by the manufacturer or manufacturer must comply with the requirements of paragraph 15.6.1 of the code.

 

15.8. Number of test samples

15.8.1 When submitting product information for a certain model in accordance with Article 6 of the Regulations, multiple test reports of the model must be submitted. Table 15.2 shows the minimum number of test samples.

 

15.8.2 The test results of the sample must be determined in accordance with the provisions of Table 15.3 and comply with the performance requirements of paragraph 15.6 of the code.

 

15.8.3. The measurement of luminous efficiency must be determined by the ratio calculated based on the average value of luminous flux and the average value of power consumption (both determined according to paragraph 15.4 of the code). The quotient obtained must be adjusted to the nearest integer (lumens/watt).
