In 2012, the European Commission issued Regulation (EU) No874/2012 on energy labeling of electric lamps and lamps, which officially replaced the 98/11/EC directive on energy labeling of household electric light sources. Regulation (EU) No 874/2012 officially stipulates the energy label requirements for the following four types of electric lamp products: tungsten filament lamps, fluorescent lamps, high-intensity gas discharge lamps, and LED lamps, and clarifies the responsibilities of suppliers and distributors.
Products that do not apply to this regulation are:
(a) Products with luminous flux less than 30lm;
(b) Lamps and LED modules sold on the market with batteries as the main power source;
(c) Lamps and LED modules whose light source's visible light range is within the range of 380~780nm that are not sold on the market;
(d) Lamps and LED modules sold on the market that are installed in lamps and consumers cannot replace the light source;
(e) Lamps and LED modules sold on the market that are part of the product and whose main purpose is not to illuminate;
(f) According to the implementation measures of the Eco-Design Directive 2009/125/EC, lamps and LED modules that did not meet the relevant requirements in 2013 and 2014;
(g) Design lamps and lanterns specially installed with the lamps and LED modules listed in (a) to (c).
In addition to meeting the general requirements of the Directive 2010/30/EU, the regulations also stipulate examples of energy efficiency labels and information requirements for electric lamps and lighting products. The details are as follows:
1. Electric light label

                                                 

in:

I is the supplier’s name or trademark
II is the supplier’s model identifier, that is, the code, usually alphanumeric, to distinguish the model of a particular lamp with the same trademark or supplier’s name
III is the energy efficiency level determined according to Table 2
IV is the weighted energy consumption EC per 1000 hours, expressed in kWh, and rounded to the nearest integer as required.
If the label is printed on the package, and the information of I, II, and IV appears elsewhere on the package, then this information may not be included on the label. The label of the product should be selected from the examples shown in Figure 2 below.
如果标签打印在包装上，且I、II、IV的信息出现在包装的其他位置，那这些信息可不包含在标签上。产品的标签应从以下图2示例任选其一。

2. Lamp labels displayed at the point of sale
The label should have a reference English translation, as shown in Figure 3:

                                       

                                        Figure 3 Examples of energy efficiency labels for electric lights
in,I is the supplier’s name or trademark
II is the supplier’s model identifier, that is, the code, usually alphanumeric, to distinguish the model of a particular lamp with the same trademark or supplier’s name
III describes whether the lamp installed in the luminaire can be replaced by the end user, the integral LED module cannot be replaced by the end user, or both.
IV is the range of energy efficiency rating
V is the content of the sentence displayed under applicable conditions. For example, if the lamp installed on the luminaire can be replaced by the end consumer, the energy efficiency level of the lamp should be included in the package of the luminaire. If necessary, the sentence can be adjusted to one lamp or several lamps, and several energy efficiency levels are listed. If the lamp contains only one integral LED module that cannot be replaced by the end consumer, the lamp should be marked with a warning to inform the consumer that the lamp cannot be replaced.
In addition, Figures 4 to 8 also provide typical lamp labels that are different from Figure 3. These labels do not need to show all possible combinations.
此外，图4-图8还提供了不同于图3的典型灯具标签，这些标签不需要显示所有可能的组合。

Pref——The reference power obtained from the common luminous flux (Φuse) of the module, calculated with the following formula:
For the module with Φuse＜1300lm, Pref =0.88√Φuse +0.049Φuse
For the module with Φuse≥1300lm, Pref=0.07341Φuse
The weighted energy consumption (EC) can be calculated by the following formula:
EC = Pcor×1000h/1000
The energy efficiency grade of the lamp can be determined according to Table 2.
