Von Lumen nach Watt YouTube

Wattage is a measure of how much electricity (or energy) a light bulb consumes to achieve its lumen output. Each type of light source — LED, fluorescent, halogen or incandescent bulbs — has a different lumen-to-watt ratio. If a 100-watt incandescent light produces 1,500 lumens, and a 10-watt LED light does the same, the 10-watt LED bulb may.
