Enter the power consumption and luminous efficacy into the calculator to determine the total amount of light in Lumens. This calculator can also evaluate any of the variables given the others are known.
Watts To Lumens Formula
The following formula is used to calculate the conversion from Watts to Lumens.
L = W * lm/W
Variables:
- L is the total amount of light in Lumens (lm)
- W is the power consumption in Watts (W)
- lm/W is the luminous efficacy in Lumens per Watt (lm/W)
To calculate the total amount of light in Lumens, multiply the power consumption in Watts by the luminous efficacy in Lumens per Watt. The result will give you the total amount of light produced by the source in Lumens.
What is Watts To Lumens?
Watts to Lumens is a conversion that measures the total amount of visible light emitted by a source in terms of its power consumption. Watts is a unit of power that indicates the rate of energy conversion or transfer, typically used to measure electrical or mechanical power. Lumens, on the other hand, is a unit of luminous flux in the International System of Units, used to quantify the amount of light produced by a source. Therefore, the Watts to Lumens conversion helps to understand the efficiency of a light source in terms of the light output for each unit of power consumed.
How to Calculate Watts To Lumens?
The following steps outline how to calculate the Watts To Lumens using the formula: L = W * lm/W
- First, determine the power consumption in Watts (W).
- Next, determine the luminous efficacy in Lumens per Watt (lm/W).
- Next, gather the formula from above = L = W * lm/W.
- Finally, calculate the total amount of light in Lumens (lm).
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
power consumption in Watts (W) = 60
luminous efficacy in Lumens per Watt (lm/W) = 100
