1) When is a company required to Test LED Energy Efficiency and the  Declare LED Energy Labeling?

Based on the minimum Energy Efficiency level for the list of means and equipments subject to Energy Labeling according to regulations and implementation schedule (Decision No. 04/2017/QD-TTG).

  • In Clause 1, Article 1, Decision No. 04/2017/QD-TTG clearly states that LED lights are on the list of means and equipment subject to energy labeling and application of minimum energy efficiency.
  • Quote from point b, Clause 1, Article 2 of Decision No. 04/2017/QD-TTG regulates the implementation schedule of energy labeling with the content: “Implementation of voluntary energy labeling until the end of December 31st, 2019 for: LED products, hot water heaters with reserve tanks”

=> This means companies are allowed to Test LED Energy Efficiency and Voluntary LED Energy Labeling until December 31st , 2019. From January 1st , 2020, companies are required to Test Energy Efficiency and Declare Energy Labeling for LED lights.

2) Does the Ministry of Industry and Trade have any documents guiding companies to implement the Energy Labeling Declaration for LED lights?

On December 27th, 2018, the Ministry of Industry and Trade issued Decision No.4889/QD-BCT regulates the Publication of Technical Standards and issues guidelines for Declaration of Efficiency and energy labeling applicable to the program of Energy labeling for LED lighting products. Including the areas of application, testing standards, subjects must carry out energy labeling procedures, as well as technical requirements for LEB lights involving in the energy labeling program …

3) Which LED lights are under the National Energy Labeling Program?

Pursuant to Decision No. 4889/QD-BCT, Article 2, Chapter I regulates energy efficiency testing standards of LED lights labeled as:

Quote from Section 1 (Areas of application) of TCVN 11844:2017 has the following provisions:

 “This standard regulates energy efficiency levels for self-ballasted LED lights with E27 and B22 heads and double-headed LED lights designed to replace tubular fluorescent lights with G5 AND G13 heads, used for general purposes, with a power of up to 60 W, a nominal voltage not exceeding 250 V.”

Therefore, the LED lights of the energy labeling program must meet all 3 following factors:

  • LED lights with lamp head code is one of the following lamp head codes: E27, B22, G5 and G13
  • LED lights with power up to 60 W
  • LED lights with nominal voltage not exceeding 250 V

If LED lights lack at least one of the three criteria above will be part of the voluntary energy labeling program and no mandatory declaration and labeling is required.

4) Which laboratories are designated by the Ministry of Industry and Trade to Test Energy Efficiency of LED Lights?

Phuc Gia – Vilas 1212 Laboratory is one of the units designated by the Ministry of Industry and Trade to test Energy Efficiency of LED Lights under the certificate of registration of energy efficiency testing No. 2181/GCN-BCT.

To find out if the Laboratory that you are planning to test there is designated or not, please contact the lab to ask for the Ministry of Industry and Trade’s decision for that lab. Or you can go to the official website of the Ministry of Industry and Trade to check

5) What technical requirements are required for LED lights in the Energy Labeling Program?

According to section 5, chapter II, Decision 4889/QD-BCT – Technical requirements for LED lights in the energy labeling program:

Technical requirements for led lights in the energy labeling program include:

5.1. Capacity: The measured average value cannot exceed 108% of the nominal value. The measured value of all samples shall not be greater than 115% but not less than 85% of the nominal value.

5.2. Lights luminous flux: The measured average value shall not be less than 90% of the nominal value, and the measured value of all samples shall be greater than or equal to 85% of the nominal value.

5.3. Minimum life time is: 12,000 hours

5.4. Safety requirements

Products participating in the energy labeling program must ensure safety requirements according to current regulations:

5.5. Energy efficiency

The energy efficiency is calculated as the ratio of the measured initial luminous flux to the measured initial power.

For self-ballasted LED lights with E27 and B22 heads and double-headed LED lights designed to replace tubular fluorescent lighst with G5 and G13 heads, the Energy efficiency levels shall not be lower than those specified in Tables 1 and Table 2

Table 1. Luminous efficacy values for self-ballasted LED lights

Energy efficiency level Initial luminous efficacy (lm/W)
Color temperature ≥ 4 000 Color temperature < 4 000
MEPS 70 60

Table 2. Luminous efficacy values for double-headed LED lights

Energy efficiency level Initial luminous efficacy (lm/W)
Color temperature ≥ 4 000 Color temperature < 4 000
MEPS 90 80

Other types of LED lights: No minimum energy efficiency level regulated.

In addition, according to Section 4 – TCVN 11844: 2017, LED lights should ensure the following technical standards:

  • Initial power: The measured value should not exceed 107.5% of the nominal value & The measured value of all samples must not be greater than 110% but not less than 90% of the nominal value.
  • Initial luminous flux: The average value measured should not be less than 92.5% of the nominal value, and the measured value of all samples must be greater than or equal to 90% of the nominal value.
  • Energy efficiency: The calculated average value of all samples must be greater than or equal to the values ​​specified in Tables 1 and Table 2, respectively.
  • Color rendering index (CRI): The color rendering index must be greater than or equal to 80 & The measured value of all samples must be greater than or equal to the nominal value minus 3.
  • Lumen Maintenance Factor: The luminous flux value measured at 25% of nominal life time (with a maximum of 6000 hours) shall not be less than the luminous flux value relative to the lumen maintenance factor corresponding to the maximum life time as determined and provided by the manufacturer or authorized dealer
  • Life time: The manufacturer must declare the life of the product, with a minimum value of 20,000 hours.

6) How many samples does it take for company to bring to the Testing Laboratory for Energy Efficiency Testing?

According to Table 1, Section 4.1 – TCVN 11844: 2017, the minimum number of typical test samples is 5.

Therefore, to test the Energy Efficiency of LED lights, company needs to bring a minimum of 5 samples to the Testing Laboratories to conduct Energy Efficiency Test for LED lights.

7) Fees for Energy Efficiency Testing of LED lights ?

Depend on the listed prices of each Lab, the Testing Fee at Phuc Gia Lab is listed at:

8) Time for Energy Efficiency Testing of LED lights?

Testing time will depend on each unit you want to test, usually it takes from 2 to 10 days / model. However, at Phuc Gia Testing Lab, Phuc Gia Lab always supports customers with the best testing time, so Phuc Gia Lab tests LED lights for 1-2 days / model.

9) 14 Required Information Must Be Displayed On LED lights Packaging?

According to Section 7, Chapter II, Decision No. 4889 / QD-BCT, all LED lighting products registered to participate in the energy labeling program, the packaging of LED lighting products must shows 14 following information:

1) Manufacturer

2) Model

3) Origin

4) Power (W)

5) Voltage (V)

6) Frequency (Hz)

7) Luminous flux (lm)

8) CCT, CRI indicators (applicable to modules, LED lights emit white light)

9) Color temperature (°K)

10) Life time: calculated in hours (h)

11) Energy efficiency (lm/W)

12) Power factor

13) Power consumption after 1000 hours: (kWh)
