Regulations Governing Amendments to Energy Efficiency Standards and Marking Methods of Energy Conservation Label for Indoor Lighting Neng-ji-zi No. 10805010700 was announced on August 23, 2019 and became effective on September 1, 2020.

I. The applicable scope, energy efficiency test conditions and methods, and energy efficiency standards for certification of energy conservation label for indoor lighting (hereinafter referred to as ‘lighting’) should comply with the following regulations:
(I) Applicable scope: Lighting that comply with the National Standards of the Republic of China (CNS): CNS 14335 and CNS 14115, exclusive of counter, table, bed and floor lighting or those considered as non-compliant by the Bureau of Energy, Ministry of Economic Affairs
(II) Energy efficient test conditions and methods:
1. Candlepower distribution: tests are conducted in accordance with the International Commission on Illumination (CIE) standards: CIE 70, CIE 84, and CIE 121; the spacing between test angles for curve measurement should be below 2.5°.
2. Color temperature and color rendering index (CRI):
(1) Light-emitting diode (LED): tests are conducted in accordance with CNS 15437 “Recessed LED lighting for T-bar ceiling systems.”
(2) Fluorescent lamp: tests are conducted in accordance with CNS 691 “Fluorescent lamps (for general lighting service).”
(3) For light sources not specified in the CNS, similar light source standards shall apply.
3. Unified glare rating (UGR): tests are conducted in accordance with CIE 117. Coefficients for test conditions are as follows:
(1) Ceiling reflectance is 0.5.
(2) Wall reflectance is 0.5.
(3) Floor reflectance is 0.2.
(4) Simulated indoor climate coefficients are 4H in length and 3H in width (H stands for height).
(4) Test conditions and methods for lighting with adjustable light/color point are the same as those for CNS 16027 G5/G13 “Double-capped LED tubular lamps” or CNS 15630 “Self-ballasted LED lamps with adjustable light/color point.”
5. Flicker: tests are conducted in accordance with CIE TN 006:2016.
(III) Commonality requirements:
1. The actual measured input power should be within ± 10% of the rated input power. Rounding to the first decimal point is adopted for calculation.
2. The actual measured power factor value should be greater than or equal to 0.9, and more than 95% of the marked value. Rounding to the second decimal point is adopted for calculation.
3. The actual measured CRI value should be greater than or equal to 80.0 and not lower than the marked value after subtracting 3 from it. Rounding off to the first decimal point is adopted for calculation.
4. When the light source is LED, the CRI R9 is greater than 0.
5. The actual measured UGR value should be less than or equal to 19.0. Rounding off to the first decimal point is adopted for calculation.
6. Light types:
(1) For the plane of C=0° to C=180° in Figure 1, the reference axis is the axis across from the pivot of the light-emitting areas for lighting; it is vertical to the light-emitting areas. The candela of its vertical angle 0° is 0.65 to 0.85 times the maximum candela of said plane.
(2) For the plane of C=0° to C=180° in Figure 1, the angles for the maximum candela of its half: ϴ1 and ϴ2 are greater than 38°, with a sum greater than 80°.
(3) The accumulated luminous flux within 80° solid angle of the reference axis in Figure 2 should be more than 80% of the total luminous flux. Luminaires with upward light output are not subject to the rule.
(4) Rounding off to the first decimal point is adopted for the above calculation of the actual measured luminous flux value.
7. The upward light ratio (ULR) of suspension lighting with upward light output should be between 7% and 14% after performing the calculation according to the following equation:
ULR = (upward luminous flux of lighting (> 90°))/total luminous flux of lighting × 100%
8. The actual measured luminous flux should be between 90% and 120% of the rated luminous flux. Rounding off to the nearest integer is adopted for calculation.
9. Rounding off to the first decimal point is adopted for the calculation of the actual measured lumen maintenance. The results should comply with the following:
(1) Pass a 1,000-hour test with the actual measured lumen maintenance value of more than 97%.
(2) Pass a 3000-hour test with the actual measured lumen maintenance value of more than 95%.
10. Photobiological safety must comply with CNS 15592 “Hazard free.”
11. All lighting must be smaller than or equal to 0.02 of the flicker index (FI), as well as smaller than or equal to 2% of the percent flicker (PF), regardless of their light output frequency.
(4) Energy efficiency standards: rounding to the first decimal point is adopted for calculation of the actual measured luminous efficiency value. After performing the calculation according to the following equation, the actual measured luminous efficiency value should be more than 125.0 lm/W, and more than 95% of the marked value.
Actual measured luminous efficiency (lm/W) = total luminous flux (lm))/total input power (W)
II. Energy conservation labels should be obtained for light sources and ballasts used by lighting that are required to meet energy conservation requirements. However, this rule does not apply when no certified products in the categories of said light sources and ballasts are available.
III. A vendor shall attach the following safety specification documents when applying for energy conservation labels for lighting.
(1) A CNS 15438, CNS 15983, or CNS 62931 test report shall be attached for lighting with a LED tube as their light source. Also, the LED tube model should be displayed.
(2) Other safety specification documents pursuant to the resolutions of the Energy Conservation Label Application Review Committee.
IV. The energy conservation label’s energy efficiency marking for lighting shall comply with the following:
(1) The name and address of the user must be clearly marked on the product or package.
(2) If the user is an agent, the name and address of the manufacturer must be clearly marked on the product or package.
(3) The rated power, total luminous flux, CRI, color temperature, luminous efficiency, power factor, photobiological safety, FI, and PF of a product should be displayed in the product catalog.

Actual measured luminous efficiency (lm/W) = total luminous flux (lm))/total input power (W)
