Requirements on  Minimum Energy Performance Standard, Energy Efficiency Indication , and 
Inspection for Double -Capped LED Lamps  
 
Subject：Announcement for the Requirements on Minimum Energy Performance Standard , 
Energy Efficiency Indication , and Inspection of`  Double -Capped LED Lamps  
 
Legal Basis： Paragraph 4, Article 14 of the Energy Administration  Act 
Announcement s： 
1. The double -capped LED lamps (LED lamps) herein this Announcement are those meeting the 
definition of LED lamps in National Standards of the Republic of China (CNS) 16027, and 
promulgated by the Bureau of Standards, Metrology and Inspection (BSMI) of the Ministry 
of Economic Affairs (MOEA) as products requir ing inspection. However, this Announcement 
and the Requirement do not apply to LE D lamps that the rated value and the measured 
value of Color Rendering Index (CRI) are both above 95.  
2. LED lamps shall comply with the following requirements:  
(1). Initialization va lue of measured power consumption of LED lamps shall be examined in 
accordance with the relevant regulations set forth in CNS 16027, and it shall be rounded 
off to the first decimal place. The initialization value of measured power consumption 
shall be bet ween 90% and 110% of the rated value. However, for LED lamps with the 
rated power below 5.0W, the initialization value of the measured power consumption 
shall be between 80% and 120% of the rated value.  
(2). Initialization value of measured luminous flux of LED  lamps shall be examined in 
accordance with the relevant regulations set forth in CNS 16027, and it shall be rounded 
off to the nearest integer. The Initialization value of the measured luminous flux shall be 
between 90% and 120% of the rated value.  
(3). Measur ed Luminous Efficacy of LED lamps shall be examined in accordance with the 
relevant regulations set forth in CNS 16027, and the measured value of Luminous 
Efficacy shall be rounded off to the first decimal place. The measured value shall not be 
lower than 95% of the rated value and the value mentioned in the minimum energy 
performance standard (MEPS) of LED lamps (Table 1).  
3. The rated power consumption, rated luminous flux and rated luminous efficacy shall be 
marked on LED lamps or the smallest package of LE D lamps.  
4. The Central Competent Authority may conduct annual product sampling in accordance with 
Guidelines for Energy Efficiency Labeling Inspection and Energy Efficiency Sampling of 
Designated Energy Using Equipment and Devices while conducting energy eff iciency 
inspection. The model number and quantity of testing sample shall be designated by the 
Central Authority, and manufacturers shall send product samples to designated testing 
laboratories within allowed time limit.  
For products fail to meet the requirements in section 2, the Central Competent Authority 
will request related manufacturers to re -submit samples for re -testing. The re -tested 
samples shall be of the same model and twice as many as the first -tested samples. All the 
incurred cost associa ted with the re -testing shall be borne by manufacturers.  
If manufactures do not conduct re -testing, or not all re -tested samples meet the energy 
efficiency requirements, actions will be taken according to Article 21 and Article 24 of the 
Energy Administrat ion Act.
