The advantage is that they are a lot more economical!  This set contains 4 pieces. Please note: LED lamps have new energy labels. The new classification runs from A to G, instead of A++ to E. As a result, many lamps that previously had the A++ label now receive the E label. This does not mean that the LED lamps we sell are less durable. Below you will find a link to an article with more explanation about the new energy labels.

With LED lighting, 95% of the energy is converted into light. This means that only a small part is converted into heat, so energy consumption remains significant. An LED lamp can therefore produce as much light as an incandescent or halogen lamp with only a small part of the current. In addition, LED lighting does not get hot, so the chance of burning out is much smaller than with an incandescent lamp. LED can also withstand shocks and vibrations better. LED lighting can therefore last up to 50,000 hours. A big difference compared to the incandescent lamp with a maximum of 1000 burning hours and a halogen lamp of 3500 burning hours.
