The photo story shows you briefly what you should bear in mind when switching to efficient LED lighting:
It makes most sense to replace the lamps or illuminants that burn particularly frequently and for a long time. Then check which type of base you need and how large the LED lamp can be so that it fits into the old lamp. Last but not least, you only have to choose a certain brightness with the lowest possible wattage (= luminous efficacy) and colour temperature.

Here you can see that a conversion to LED really pays off – not only for the environment, but also for your wallet: Replacing a 60 watt light bulb with an efficient LED saves almost 16 euros in electricity costs every year. And that’s just the saving of a single lamp!
