Modern strings of lights with LED technology are replacing conventional light decorations with bulbs. And rightly so: Those who decorate their balcony, Christmas tree or house with LEDs save electricity and money. “Despite the somewhat higher initial outlay, the investment is worthwhile because LED light decorations are more economical and extremely long-lasting. What’s more, they also perform better in terms of safety,” says Thomas Haupt, a product safety expert at TÜV Rheinland.
Labelling must be clearly identifiable
If strings, tubes or nets of lights are to last longer than just one Christmas season, they should be bought only from trustworthy retailers. It is also important for the safety instructions in the relevant local language and the name and address of the manufacturer to be displayed on the packaging. Another thing you should look for when purchasing lights is the GS mark . This stands for tested safety and is issued by service providers including TÜV Rheinland. For outdoor lighting, the code IP44 is very important. This shows the consumer that the lights are suitable for outdoor use and are weather-proof.
Use only power adapters with the GS mark
LED light decorations are generally safer than traditional strings of lights, because LEDs manage with lower electric voltage. This function is performed by an upstream safety power adapter, which reduces the power outlet voltage. This means that the user is no longer at risk of an electric shock if a string of lights is damaged – which can happen when it is wound up and stored away. A safe string of lights should ideally have two test marks : One on the product and one on the power adapter.
