How to convertelectric powerinwatts (W)to luminous flux in lumens (lm). You can calculate lumens from watts and luminous efficacy. Watt and lumen units represent different quantities, so you can't convert watts to lumens. Watts to lumens calculation formula ...
Enter the luminous flux in lumens, luminous efficacy in lumens per watt and press the Calculate button to get the power in watts:Enter luminous flux in lumens: lm Enter light source: Or enter luminous efficacy in lumens per watt: lm/W Power result in watts: W...
If you want to carry out a conversion from lumens to watts, you can use the following formula: watts = lumens ÷ (lumens per watt) What is the (lm/W) figure? lm/W stands forlumens per wattand is a unit measuring luminous efficacy and energy efficiency - how much visible light is pr...
On the other hand, you can also use the calculator to convert lux to watt, and then you will know how much power you need to get a well-lit area. If the surface area is unimportant to you, and you know the bulb's brightness, you may want to use our other tool: lumens to watts...
