Energy saving tips

Tips for saving energy in your home with the right lighting

Indoor and outdoor lighting is not only a comfort factor in both rented and owner-occupied housing but also a cost factor. Therefore, energy-efficient lighting has a great potential to save you money. Energy-saving light bulbs and lamps can be installed in no time at all. There are many energy-saving tips which you can implement immediately to reduce costs and protect the environment.

Important things to know

Energy efficiency class

Energy efficiency class

Energy efficiency must be understandable to the consumer. This is the purpose of the energy efficiency class. Since 1 March 2021, a new energy label has been in force, removing the confusing A+, A++, and A+++ classes and reassessing all light sources for the future.



The lifetime of light sources indicates how many hours the light source lasts. For example, an LED bulb with a lifetime of 25,000 hours will last over ten years if used for 6 hours; per day, saving you replacement costs and reduces waste production. Another easy saving tip is to remember to turn off the light when not needed.

Socket & Base

Socket & Base

All conventional lights have a light socket (E27, E14, GU10, etc.), and you can easily screw the appropriate LED light-bulb. Since lighting is a daily necessity, switching to LEDs offer great overall savings potential.

Quick check: How can you save energy in the household?

You can start saving home energy immediately with the help of lighting: a new light source for the conventional sockets. If you're looking for a new light, such as a pendant light for the dining room, we recommend a light with permanently installed LED lighting technology in the future. If you are currently renovating your home, you should consult a lighting planner - the correct placement of power outlets can make the lighting concept more application-oriented and thus more efficient.

Efficiency example

An incandescent lamp converted 95% of the energy absorbed into heat and only 5% into light. Therefore, the wattages had to be very high to achieve sufficient brightness. As a result, the bulbs became very hot, among other things. With newer lighting technologies, the watt-to-lumen ratio, known as luminous efficacy, is improving more and more. Therefore, more brightness is possible with less energy. The lumen value is there so the consumer can compare different lighting technologies.

Lighting Technology Comparison

The development of energy-saving light sources always focuses on sustainability and environmental aspects. Longer-lasting, more energy-efficient lighting technologies reduce CO² emissions. The most energy-efficient lighting technology on the market is LED. In addition to the high luminous efficacy (power to light ratio), LEDs have the longest lifespan and a high switching resistance - frequent switching on and off (switching cycles) hardly reduces the lifespan.

Replace bulbs and use LED

The easiest way to save energy in lighting is to replace the bulb. The most energy-efficient bulb is the LED bulb, which is available for all standard sockets. This is called an LED retrofit bulb. It is easy and cost-effective to switch to LED for all conventional lighting technologies, including halogen and fluorescent lights.

How do I read a light bulb package?

Due to modern lighting technologies and more choices regarding light colour, control options and dimmability, a light-bulb package today contains much more information than in the past. We have prepared a guide to help understand everything you need to know when buying light sources.

Lights with permanently integrated LED technology

A luminaire or a lamp is the electrical appliance in which the bulb (light source) is inserted. A luminaire is, for example, a pendant or table lamp into the socket of which the bulb is screwed. With modern LED luminaires, this distinction no longer always applies: lamps and luminaires are often the same single product. In addition to high energy savings, a modern LED lamp has a long lifespan and therefore requires no maintenance - you never have to replace the bulb, reducing the waste production.

What are the advantages of LED lights?

Minimalist design

LED lighting technology is very compact and thus allows minimalist shapes that perfectly fit the modern style of living.

When is an LED light worthwhile?

If you are considering purchasing a new light (for example, because your old one no longer suits your decor), LED lamps are the best choice in terms of energy savings and modern design. The compact lighting technology makes very thin shapes possible, such as the LED panel. LED panels are unbeatable in terms of light distribution over a large area, convenient dimming abilities, and other smart features.

Save electricity: More tips

With these electricity-saving tips, additional energy can be saved - for the most part without extensive renovation work.

Solar lights

Solar technology in the garden and around the house is a great way to save energy on your outdoor lighting. Besides decorative solar lights, there are many practical outdoor wall lights, path lights, and more.

Motion sensor

Lights with motion sensors and automatic switch-off can provide a noticeable change in power consumption. The twilight sensor ensures that the light only switches on when the ambient brightness is low and with the precesne of individuals.

Smart Home

Smart home lighting can be controlled on the move, which reduces energy consumption. For example, you can switch off the lights if you realise you forgot to switch them off while at work. In addition to manual control, the light sources can also be connected to smart motion sensors that switch on only when needed.

Light switch

Turn off the light

The simplest power-saving tip is to turn off lights when they are not needed. Often people forget to turn off the lights, which continues to consume electricity unnecessarily. If it is difficult to reach the switch, for example, for people with walking difficulties, it is advisable to use smart control via an app.

Easy retrofitting of smart lighting control

Bright lampshades

Bright lampshades made from fabric or plastic, such as polyethylene are more transparent. They do not "swallow" as much light as dark shades. As a result, more light enters the room. Lower brightness and lower energy consumption from light sources are therefore sufficient.

Light ceilings and walls

Light colors such as white or pastels on the walls and ceilings reflect more light than dark shades. Due to good light reflection, light sources with lower brightness are sufficient for a pleasant illumination of the surroundings. A bright interior can therefore also save energy.

Fans with winter operation

The warm air from the radiator or stove accumulates under the ceiling in winter. The result is cold feet. A ceiling fan with winter operation ensures the warm air is distributed in the room, reducing heating costs and ensuring a better indoor climate.

Smart heating control

A smart heating system is economical. Smart radiators evaluate consumption data and react to open windows and presence, so heating energy is used more efficiently. It saves money and protects the environment - even in rented apartments due to control units that can be taken with you when you move.

Retrofit smart heating control

Lighting design and renovation

In older buildings, the distribution of elecrical outlets is not adapted to modern living. As a rule, ceiling lights are planned with a central connection in the room, wall connections do not exist, and there is not many sockets. If renovating, you should consult a lighting planner or lighting designer because placing the sockets in the right place ensures an efficiently designed lighting concept. This factor can have an impact on energy consumption as well as a sense of well-being. The lighting design includes:

Ceiling connections

A ceiling connection in the middle of the room is not always enough for a sensible lighting concept, for example, for a kitchen-dining room combination. This will result in a ceiling light which consumes a large amount of electricity and needs to be switched on at all times to light up all areas. Better is several sockets to which the right lights with the right brightness are connected and independently light different zones.

Wall connections

Wall connections often do not exist at all. Yet they can provide good, standard lighting and be a sensible addition to the lighting concept. For example, instead of a ceiling light that shines too brightly and may be uncomfortable, wall lamps can be switched on to create a relaxing atmosphere, while an LED reading lamp casts sufficient light on the pages of a book if desired.



Sockets are always important in lighting design and home renovation because they allow the option of installing flexible lighting solutions, including floor lamps and table lamps. These can be suitable for many activities, such as reading and relaxing. When general lighting is not needed, the bright, powerful and power-consuming "big" lights from the ceiling can remain switched off, saving overall energy.
