What does the E stand for in light bulbs?

The E in light bulbs is an international standard that indicates the energy efficiency of household appliances. The E stands for energy efficiency and is used as a quality mark on light bulbs and other energy-efficient products. The E on light bulbs is part of the EU label that rates the energy efficiency of household appliances. Since 2021, all light bulbs and other energy-efficient products must bear the E-label. This label indicates how efficient the bulb is and informs the consumer how much energy it uses. The E-label on light bulbs consists of a seven-stage color coding system that shows the buyer the energy efficiency of the light bulb at a glance. The higher the class, the higher the energy consumption.

The color coding key is staggered as follows:

  • A++: The most energy efficient light bulb.
  • A+: Very energy efficient.
  • A: Energy efficient.
  • B: Moderately energy efficient.
  • C: Less energy efficient.
  • D: Low energy efficiency.
  • E: Very low energy efficiency.

The E-label is an important tool that helps consumers choose energy-efficient light bulbs. The aim is to help consumers buy the most energy efficient products to save energy and money. Light bulbs with the E mark are usually more expensive than traditional light bulbs because they are more energy efficient. However, these higher costs are offset by lower energy consumption in the long run. An E-marked light bulb can use up to 80 percent less electricity than a conventional light bulb.

For people who value energy efficiency, it is important to know what the E in light bulbs stands for. This label helps buyers find the most energy efficient bulb for their individual needs. It is an important tool for saving energy and money. The E-label is an important part of the EU energy efficiency label and an important tool for purchasing energy-efficient household appliances. It helps consumers choose the best products to save energy and money. Therefore, it is important to know what the E stands for in light bulbs.
