Selection Criteria television sets

Methodology

Topten.eu – Best Products of Europe – presents the most energy efficient television sets of Europe.

Technical criteria

In order to be displayed on topten.eu, television sets have to be declared according  to the Commission regulation on energy labelling of televisions from September 2010 and to IEC 62087:2008 and must comply the following criteria:
  • Energy efficiency class:
    • Class A (EEI < 0.3) or better for TVs with a screen diagonale of up to 100cm
    • Class A+ (EEI < 0.23) or better fot TVs with a diagonale > 100cm
  • Max. power consumption in On mode: 90 Watt
  • Max. power consumption in standby: 0.5 Watt
  • Available in at least one European country

Relevant values have to be provided by the producers. Producers who are not able to provide these values cannot claim to have their appliances displayed on topten.eu. All declarations can be verified by random measurements.

Data sources

  • Producers’ declarations
  • National data-bases and Topten-sites

Order of presentation

Products are ranked according to their efficiency index. The order of presentation can be changed by clicking the tables’ headings.

Glossary

Brand, Model, Similar Models

The brand names and model names are on the list. Products of similar construction and identical technical values are displayed only once. Similar models’ names are listed under ‘similar models’.

Electricity Costs

According to the following assumptions:
  • Product’s lifetime: 10 years
  • Energy consumption: daily 4 hours in On mode, 20 hours in standby mode
  • Tariff of electricity: 0.15 €/kWh (this should be understood as order of magnitude as there can be large differences depending on country or electrical utility)

Screen diagonal

Diagonal of the visible screen in cm. In shops the diagonal is often indicated in inches (1 inch = 2.54 cm, example: 102 cm = 40 inch).

High Definition

‚HD-ready‘, ‚HD-ready 1080p‘ and ‚Full HD‘ indicate the screen resolution in pixels:
  • HD-ready: at least 1280 x 720 pixels
  • HD-ready 1080p: at least 1920 x 1080 pixels
  • ·Full HD (True HD und Full HD 1080p): at least 1920 x 1080 pixels

Resolution

Maximum resolution in number of pixels (horizontal x vertical).

Brightness

The image’s typical brightness (luminance) in candela per square meter (cd/m2).

DVB-Receivers

Receivers for digital TV integrated in the TV set:
  • DVB-T: Terrestrial (for antenna)
  • DVB-S: Satellite (for satellite dish)
  • DVB-C: Cable (for cable)

Technology

In LCD TVs (LCD = Liquid Crystal Display) the LCD layer (=panel), which consists of millions of  red, yellow and blue pixels individually varying their translucence, produces an image by selectively filtering light from a backlight. The LCD layer does not glow by itself, but has to be illuminated by a backlight. Common backlight technologies for LCD TVs are CFLs (CCFL: Cold Cathode Fluorescence Lamp, HCFL: Hot Cathode Fluorescence Lamp). A new and efficient backlight technology is LED (Light Emitting Diode).

Power On

Power consumption in On mode in Watt according to IEC 62087:2008.

Power Standby

Power consumption in Standby mode in Watt according to IEC 62087:2008.

Efficiency Index and Energy class

According to the Commission regulation on energy labelling of televisions from 28. September 2010 and IEC 62087:2008. The energy efficiency index (EEI) is the ratio between annual consumption of the appliance and a standard consumption of a typical similar model. The smaller the index, the better is the energy efficiency of the appliance.

Countries available

Countries in which a product is available according to producers delarations; country codes according to ISO.
EU = available throughout the European Union
On demand = producers could not indicate the availability and consumers have to ask on their own
