Taiwan Formulates LED Lamp Energy Efficiency Benchmarks Recently, the Ministry of Economic Affairs of Taiwan issued an announcement setting out the “ballast energy efficiency benchmark for built-in light-emitting diode (LED) bulbs”, which will take effect on July 1, 2014.

The announcement pointed out that the ballast built-in LED bulbs (hereinafter referred to as LED bulbs) that are applicable to this benchmark should meet the standard CNS 15630 specifications and be declared by the Ministry of Economic Affairs and Standards Inspection Bureau as the scope of the inspection products. However, if the rated color rendering index (CRI) is above 95, the benchmark is not applicable.

According to the announcement, the luminous efficiency of LED bulbs should be above the value of the attached table. The measured input power of the LED bulb is calculated to the first digit after the decimal point, and the second digit after the decimal point is rounded off; the measured luminous flux is calculated to the whole digit, and the first digit after the decimal point is rounded off; the luminous efficiency is calculated to the first digit after the decimal point. The second digit after the decimal point is rounded off.
