LED Energy Formula
The following equation is used to calculate the LED Energy.
Eled = Pled * T
Variables:
- Where Eled is the LED Energy (Joules)
- Pled is the led power usage (watts)
- T is the led run time (s)
How to Calculate LED Energy?
The following two example problems outline the steps and information needed in order to calculate the LED Energy.
Example Problem #1:
- First, determine the led power usage (watts). In this example, the led power usage (watts) is measured to be 86.
- Next, determine the led run time (s). For this problem, the led run time (s) is calculated to be 49.
- Finally, calculate the LED Energy using the formula above:
Eled = Pled * T
Inserting the values from above and solving the equation with the imputed values gives:
Eled = 86*49 = 4214 (Joules)
Example Problem #2:
Using the same process as example problem 1, we first define the needed variables outlined by the formula. In this case, the values are provide as:
led power usage (watts) = 60
led run time (s) = 4
Entering these values into the formula or calculator above gives us: Eled = Pled * T = 60*4 = 240 (Joules)
