Article number: 5410288291253 View all Sylvania products > View more: GU10 LED lamps > The new Sylvania series is perfect for decorative and general lighting applications, creating a warm ambiance similar to traditional lamps. This model can be used for education, hospitality, museums & galleries, offices, or in your home, for example. Please note: LED lamps now have new energy labels. The new classification ranges from A to G, instead of A++ to E. As a result, many lamps that previously had an A++ label now have an E label. This does not mean that the LED lamps we sell are less sustainable. Below you will find a link to an article with more explanation about the new energy labels.

The wattage is the energy consumption of the lamp. The wattage is the consumption per hour. A 60W lamp that is on for 10 hours therefore consumes 60 x 10 = 600 Watt-hours. What are lumens (lm)? Lumens are a unit of light output. The higher the number of lumens, the more light the lamp emits. This has nothing to do with the color of the light. To compare lamps, it is best to compare the number of lumens. The higher the number of lumens, the higher the amount of light. Environmental information about LED lamp - GU10 - 345lm - Reflector - Dimmable Unlike traditional lighting, LED lamps use much less energy. With LED lighting, 95% of the energy is converted into light. This means that only a small part is converted into heat, which keeps energy consumption significantly lower. An LED lamp can therefore produce as much light as an incandescent or halogen lamp with only a fraction of the power. In addition, LED lighting does not get hot, which means the risk of burnout is much lower than with an incandescent lamp. LED also copes better with shocks and vibrations. As a result, LED lighting can last up to 50,000 burning hours. A big difference compared to incandescent lamps with a maximum of 1000 burning hours and halogen lamps with 3500 burning hours.
