Watts to lumens 계산기

전기 power in watts (W) to luminous flux in lumens (lm) 계산기 and how to 계산.

Enter the power in watts, luminous efficacy in lumens per watt and press the 계산 button to get the luminous flux in lumens:

Enter power in watts: W
Enter light source:
Or enter luminous efficacy in lumens per watt: lm/W
   
Luminous flux 결과 in lumens: lm

* the predefined luminous efficacy values are typical / average values.

Watts to lumens calculation

Energy saving lamps have high luminous efficacy (more lumens per watt).

The luminous flux ΦV in lumens (lm) is equal to the power P in watts (W), times the luminous efficacy η in lumens per watt (lm/W):

ΦV(lm) = P(W) × η(lm/W)
