How do you convert lumens to Watts?
Lumen and watt units represent different quantities, so you can’t convert lumens to watts. Lumens to watts calculation formula The power P in watts (W) is equal to the luminous flux ΦV in lumens (lm), divided by the luminous efficacy η in lumens per watt (lm/W): P(W) = ΦV(lm) / η(lm/W)
How do I calculate the luminous efficacy in lumens per watt?
The first step is to enter 5000 as the value of the luminous flux in lumens and select fluorescent lamp as the light source. The luminous efficacy in lumens per watts is automatically determined by the calculator as it is displayed in the text field. Click the ‘Calculate’ button to perform the calculation.
