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...
Step 3: Understand Efficacy (Lumens/Watt) Now that we understand watts and lumens, we can use both terms to come up with lumens per watt or “efficacy” (or “luminous efficacy”). This is a measure of how well a light source converts energy (watts) into light (lumens). The old tec...

The illuminanceEvin lux (lx) is equal to the power P in watts (W), times the luminous efficacyηin lumens per watt (lm/W) divided by the surface areaAin square meters (m2): Ev(lx)=P(W)×η(lm/W)/A(m2) Lux definition
Due to their long operating life expectancy (>50,000 hours) and high luminous efficacy (70 lumens per watt and higher) high brightness white LEDs are increasingly being used to replace conventional fluorescent, compact fluorescent and incandescent light sources. It was not until LEDs emitting in ...
