Saving energy at home: 10 tips for saving electricity with LEDs

Lighting accounts for around 12 percent of your private electricity bill. You can easily save electricity here. The most important step: replace all lights that burn for more than half an hour a day with energy-saving LEDs. Your investment will quickly pay off again in times of rising energy prices. In addition to your wallet, you also relieve the environment through lower CO2Emissions. Read here how you can save a lot of electricity on lighting with our energy saving tips.

1.) Switch to LED

Those who replace their conventional lights with LEDs can save up to 80 percent of the power consumption for lighting. This is mainly due to the fact that LEDs convert the energy used into light much better than conventional light sources. A white incandescent lamp, for example, only converts five percent of the energy it consumes into light. In the case of LEDs, this value is seven times higher.

As a rule, you can simply continue to operate your previous lights with LED light sources without conversion or rewiring. This is made possible by so-called LED retrofits, a special LED light source that can perfectly replace incandescent and halogen lamps as well as fluorescent tubes.

When you switch, also think about your outdoor lighting. Here you can also rely on LEDs, which draw their energy from solar cells.

Switching to LEDs can save a lot of electricity not only in private life, but also in companies. Use this free quick check to check your LED savings potential and how quickly the switch to LED will pay off for you.

2.) Pay attention to the service life

The additional costs for purchasing LEDs also pay off over their longer service life: 50,000 hours or more are no problem for high-quality LEDs. For comparison: an incandescent lamp only lasts 1,000 hours, a halogen lamp about 2,000 hours and a fluorescent tube about 18,000 hours on average.

It is therefore best to only buy bulbs from well-known manufacturers and with the highest energy efficiency class. They shine many times longer and use less electricity than cheap products. The energy efficiency is determined from the emitted light output (luminous flux, unit lumen) per power consumption in watts. A indicates a very high energy efficiency, G a very low one.

You can read the service life of an LED on the packaging as follows:

Example 1: 50,000 h L70B85

  • After 50,000 hours of operation, the luminaire must still emit 70% of the original light. However, only 85% of the LEDs need to be functional.

Example 2: 50,000 h L70

  • After 50,000 hours of operation, the luminaire must still emit 70% of the original light. No LEDs may have failed due to a defect.

3.) Illuminate parts of the room in a targeted manner

When choosing your lamps, make sure that you can use them to specifically illuminate different areas of a room. A single luminaire shouldn't have to bathe everything in a bright light. So you can consciously switch on the light where you need it. The ideal combination for reading: Dimmed general lighting and bright, directed light on your reading.

4.) Avoid festive lighting in the whole house

Only leave the light on in rooms that you actually use. Turn off the lights when you leave the room.

5.) Motion detectors for corridors and stairwells

In the hallway and stairwell in particular, the light often stays on for hours without being noticed. A motion detector can help here: it is simply installed in place of the light switch and automatically switches the light on or off as required. That saves electricity and is very convenient.

6.) All lights off with Smart Home

Let smart home systems help you save electricity: many devices work with default settings such as programmable lighting moods. If you want to read the newspaper on the sofa, you can switch the reading lamp on and all other lamps off at the push of a button.

7.) Dimming helps save electricity

You can dim many LED lamps. This creates a nice atmosphere and you save electricity with LEDs.

8.) Choose bright lampshades

Bright and reflective lampshades increase the luminosity. In most cases, a lamp with a lower power consumption is sufficient.

9.) Paint the walls and ceilings light

Pay attention to the color when painting: light walls reflect light better than dark ones - you need less energy to illuminate the room. This also saves electricity.

10.) Free lampshades from the shadowy existence

Regularly clean your lamps and luminaires from dust and dirt with a damp cloth: This is how these light sources maintain their luminous efficacy. Make sure that the lamp is switched off and cold beforehand.


When it comes to lighting, you can save a lot of electricity and thus money with energy-saving lamps and your own behavior. Switching to LED lights offers the greatest potential for energy savings - they can't be beaten when it comes to energy efficiency. Avoid cheap products when buying LEDs: They often have a significantly shorter lifespan than products from well-known manufacturers. You can also use modern technology to help you save energy: for example, motion detectors and smart home products.
