The number of watts is the energy consumption of the lamp. The number of watts is the consumption per hour. A 60W lamp on for 10 hours consumes 60 x 10 = 600 watt-hours. What are lumens (lm)? A lumen is a unit of light output. The higher the number of lumens, the more light the lamp produces. This has nothing to do with the color of the light. To compare lamps, it's best to compare the number of lumens. The higher the number of lumens, the more light the lamp produces. Environmental information about LED lamp - E27 - 470lm - Ball - Matte. 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, so energy consumption remains 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 the risk of burnout much smaller than with an incandescent lamp. LEDs are also more resistant to shock and vibration. LED lighting can therefore last up to 50,000 hours. A significant difference compared to an incandescent bulb with a maximum of 1,000 hours and a halogen bulb with 3,500 hours.
