Item number: 5410288301310 View all Sylvania > View more: LED bulbs E27 > Ultra High Efficiency LED bulb - E27 - 840lm - 2700K This super-efficient LED bulb has the look of a classic incandescent bulb, but consumes 95% less energy. The bulb has an E27 socket, consumes 4 watts, and has a light output of 840 lumens. This is a high-efficiency bulb, a bulb that uses very little energy yet produces a high light output. What's even more special: this bulb is one of the first to have the new energy label A, the most economical label! Note: LED bulbs have new energy labels. The new classification runs from A to G, instead of A++ to E. As a result, many bulbs that previously had an A++ label now have an 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 information about the new energy labels.

The number of watts is the energy consumption of the lamp. The number of watts is the consumption per hour. A 60W lamp that is on for 10 hours consumes 60 x 10 = 600 watt hours What are lumens? Lumen is a unit for light output. The higher the number of lumens, the more light the lamp gives. So 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 lamps - Ultra High Efficiency - E27 - 840lm - 2700K. 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 portion is converted into heat, keeping energy consumption significant. An LED lamp can therefore produce as much light as an incandescent or halogen lamp with only a small fraction of the power. Furthermore, LED lighting doesn't get hot, making it much less likely to burn out than an incandescent lamp. LEDs are also more resistant to shock and vibration. This means LED lighting can last up to 50,000 hours. This is a significant difference compared to an incandescent lamp with a maximum of 1,000 hours and a halogen lamp with 3,500 hours.
