 Requirements on Minimum Energy Performance Standard , Energy 
Efficiency Indication and Inspect ion for Fluorescent Lamps(Draft) 
 
Legal Basis ：Article 14 of the Energy Management Act 
Announcement ： 
1. Scope of the Announcement ：The fluorescent lamps denoted in this 
announcement means those lamp s 1.) defined by CNS 691as 
Fluorescent lamps(for general light ing service); 2.) whose general 
color rendering index (Ra) is less or equal to95; and 3.) belong to 
products category that requiring in spection before marketing by the 
Bureau of Standards, Metrol ogy and Inspection (BSMI) of the 
Ministry of Economic Affairs (MOEA) . 
2. Inspection method ：The luminous efficacy and Ra of fluorescent lamps 
shall be inspected according to CN S 691. The result of which shall be 
rounded to the nearest integer. 
3. Energy efficiency indication: Fluor escent Lamp shall be marked with 
luminous efficacy on product itself or its packaging. 
4. Minimum Energy Perfo rmance Standard (MEPS) ：The measured 
luminous efficacy for fluorescent lamps, either imported or 
manufactured locally, shall not be less than the energy efficiency 
requirement indicated in the Table below. Those lamps whose Ra is 
above 90 and but below or equal to  95 will be allowed 10% deduction 
of applicable luminous efficacy requirements in the Table. 
5. Compliance inspection scheme: Compliance shall be checked by 
annual sampling test. The model number  and quantity of testing sample 
shall be designated by Central Authority. Manufacturers shall deliver 
testing samples to designated laborat ory for compliance testing within a 
prescribed time limit. The testing results of luminous efficacy of samples shall be equal to or greater than 95% of marked value and shall 
be incompliance with applicable  luminous efficacy requirements 
indicated in the Table. 
Central Authority may notify the manufac turers for retesting if the first 
testing results fail to comply with the standard indicated in preceding 
paragraph. Retesting samp le shall be double in amount and identical in 
product type to samples for the first test. All expenses for retesting shall 2 
 be paid by manufacturers. 
Penalties indicated in Article 24 of  Energy Management Act will apply 
if 1.)manufacturers fail to conduct sa mpling test ; 2.) manufacturers fail 
to conduct retesting; or 3.)all retes ting results fail to meet standard 
indicated in preceding paragraph.

Note: 
1. The definition of types and classifications in the above Table follows the definition 
of CNS 691. T5 fluorescent lamps in the above Table means T15 glass tube type indicated in CNS 691.

 2. The range of Color Temperature shall be referred to the range indicated in CNS 
691： 
(1) D：5700K~7100K 
(2) CW or N ：4600K~5400K  
(3) W：3900K~4500K 
(4) WW：3200K~3700K 
(5) L：2600K~3150K 
3. According to CNS 691, the measured lumi nous efficacy (lm/W) means the ratio of 
initial luminous flux (lm) to power (W).  Initial luminous flux (lm) and power (W) 
shall be rounded off to the one decimal place.  
4. Those lamps used for hastening plant gr owth, insect repelli ng, semi-conductor use, 
and bactericidal use shell be ex empted from this announcement. 
5. If the lamp classification of products is unfit for the above Table, it shall be 
subjected to the classificati on of same type, same size and similar power (W). If 
the lamp classification of pr oducts is able to fit between two type s, it shall be 
subject to the higher requirements of lu minous efficacy of the nearest two types. 
If the numerical value of products exceeds the largest value numerical of type, it 
shall be subject to the highest luminous efficacy of same types.
