GB20054-2015
Minimum allowable values of energy efficiency and energy efficiency grades for metal-halide lamps
金属卤化物灯能效限定值及能效等级
GB 20054-2015 is a current mandatory Chinese national standard for Minimum allowable values of energy efficiency and energy efficiency grades for metal-halide lamps. It appears in the Construction compliance cluster with a energy efficiency focus and has an implementation date of Jan 1, 2017.
Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.
Compliance overview
Scope and applicability
This standard applies to transparent glass shell scandium-sodium series metal-halide lamps (single-ended 50W~1500W, double-ended 70W~250W) and ceramic metal-halide lamps (20W~400W). It is not applicable to powder-coated bulbs or explosion-proof metal-halide lamps. Manufacturers must verify their product categories against these specific wattage ranges to ensure proper compliance.
Technical requirements
The standard classifies the energy efficiency of metal-halide lamps into three grades, with Grade 1 representing the highest efficiency. It specifies the minimum allowable values for initial luminous efficacy for each grade. The mandatory minimum allowable value of energy efficiency corresponds to Grade 3. Additionally, the standard outlines requirements for lumen maintenance, referencing performance criteria from GB/T 18661 and GB/T 24458. For ceramic metal-halide lamps, specific correction factors are applied to the initial luminous efficacy based on correlated color temperature (CCT) and color rendering index (CRI). Manufacturers must calculate these corrections to determine the exact compliance threshold for their specific lamp models.
Testing methods
To determine initial luminous efficacy, the lamp must be aged for 100 hours before measuring the initial luminous flux and power consumption, as specified in GB/T 13434. The efficacy is then calculated as the ratio of luminous flux to power. Lumen maintenance testing procedures follow the respective requirements outlined in GB/T 18661 or GB/T 24458.
FAQs
What products are regulated under GB 20054-2015?
It regulates transparent glass shell scandium-sodium series and ceramic metal-halide lamps within specific wattage ranges. It excludes powder-coated and explosion-proof types.
What is the mandatory minimum energy efficiency requirement?
The mandatory minimum allowable value of energy efficiency is defined as Grade 3. Products must meet this threshold to be legally sold in the Chinese market.
Are there any updates from the previous version of GB 20054?
Yes, the 2015 version expands the scope to include double-ended scandium-sodium series and ceramic metal-halide lamps, and it has generally raised the efficiency indicators for all grades compared to the 2006 version.
