With significantly less energy consumption than traditional light bulbs, these LEDs provide bright and powerful light. This is not only good for the environment, but also for your wallet. Series Sphere Pear LED Lamp Fitting E27 Lamp power 4 W Current 42 mA Color temperature 2700 K Voltage 220-240 V Lumen/watt 118 lm/Watt Output voltage info AC V Luminous flux 470 lm Operating temp. Min -30° degrees Operating temp. Max 40 ° degrees IP rating IP20 Lifespan L90/B10 15000 h i Diameter 60 mm Length 104 mm Dimmable No 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.

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 (lm)? Lumen is the unit for 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 greater the number of lumens, the higher the amount of light.  Environmental information about LED lamp - E27 - 470 lm - bulb - clear In contrast to 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, 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.
