Converting watts to lumens isn't straightforward because watts measure power consumption, while lumens measure light output. The conversion depends on the light source's efficiency, known as luminous efficacy, which is measured in lumens per watt (lm/W). To estimate lumens from watts, you multiply the number of watts by the luminous efficacy of the light source. For example, an LED bulb with an efficacy of 80 lm/W will produce 800 lumens from 10 watts.
