the efficiency with a class from A to G the energy consumption in kW·h the volume in litres the type (small/medium/large) Air conditioners For air conditioners, the directive applies only to units under 12 kW. Every label contains the following information: the model, the energy efficiency category from A+++ to G, the annual energy consumption (full load at 500 hours per year) the cooling output at full load in kW the energy efficiency ratio in cooling mode at full load the appliance type (cooling only, cooling/heating) the cooling mode (air- or water-cooled) the noise rating in dB (where applicable) Labels for air conditioners with heating capability also contain: the heat output at full load in kW the heating mode energy efficiency category Light bulbs From 1 September 2021 Every label of light sources, including light bulbs (halogen, compact fluorescent, etc.) or LED modules/lamps, contains the following information: the energy efficiency category from A to G the electricity consumption of the lamp in kWh per 1000 hours Where the energy efficiency category is given by this table: Where, , is defined as the total mains efficacy, calculated as: Where is the declared useful luminous flux (in lm), is the declared on-mode power consumption (in watts), and is a factor between 0.926 and 1.176 depending on the light source being or not directional and being or not powered from mains. Until 31 August 2021 Every label of light bulbs and tubes (including incandescent light bulbs, fluorescent lamps, LED lamps) contains the following information: the energy efficiency category from A to G the luminous flux of the bulb in lumens the electricity consumption of the lamp in watts the average life length in hours According to the light bulb's electrical consumption relative to a standard (GLS or incandescent), the lightbulb is in one of the following classes: Class A is defined in a different way; hence, the variable percentage. Since 2012 A+ and A++ classes are added and are introduced different classes for directional lamps and non-directional lamps. Directional lamps are defined as "having at least 80% light output within a solid angle of π sr (corresponding to a cone with angle of 120°)". These lamp classes correspond roughly to the following lamp types: Since September 2009, household light bulbs must be class A, with the exception of clear (transparent) lamps. For the latter category, lamps must be class C or better, with
