The bulb has an E27 fitting, consumes 2.3 Watts, and has a light output of 485 lumens. This is a high-efficiency bulb, meaning it consumes very little energy yet has a high light output. Extra special: this bulb is one of the first to have the new energy label A, the most efficient label! Please note: LED bulbs have new energy labels. The new classification ranges from A to G, instead of A++ to E. As a result, many bulbs that previously had the A++ label now have the E label. This does not mean that the LED bulbs we sell are less sustainable. Below you will find a link to an article with more explanation about the new energy labels.

The number of Watts is the energy consumption of the bulb. The number of Watts is the consumption per hour. A 60W bulb that is on for 10 hours therefore consumes 60 x 10 = 600 Watt-hours. What are lumens? Lumens are a unit for light output. The higher the number of lumens, the more light the bulb emits. This has nothing to do with the color of the light. To compare bulbs, it is best to compare the number of lumens. The greater the number of lumens, the higher the amount of light. amount of light (lumens) energy consumption incandescent bulb (w) energy consumption CFL (w) energy consumption our LED bulb (w) 100-150 15W 200-250 20W 4W 3W 300 25W 5W 4W 400-500 40W 9W 5W - 6W 700-850 60W 11W 9W - 10W 900-1100 75W 15W >1300 100W 20W Our LED bulbs have low energy consumption with a large amount of light compared to incandescent or CFL bulbs. Environmental information about LED bulb - Ultra High Efficiency - E27 - 485lm - 2700K Unlike traditional lighting, LED bulbs 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, significantly reducing energy consumption. An LED bulb can therefore produce as much light as an incandescent or halogen bulb with only a fraction of the electricity. In addition, LED lighting does not get hot, which greatly reduces the risk of burnout compared to an incandescent bulb. LED can also withstand shocks and vibrations better. LED lighting can therefore last up to 50,000 burning hours. A significant difference compared to incandescent bulbs with a maximum of 1000 burning hours and halogen bulbs with 3500 burning hours.
