A lumen is a unit of luminous flux. It is represented by the abbreviation 'lm'.

One lumen equals the amount of light emitted in a solid angle from a source that radiates to an equal extent in all directions.

How do you calculate the efficiency of a light bulb?

To calculate the efficiency of a light bulb, you would divide the light output (measured in lumens) by the power input (measured in watts). This will give you the number of lumens per watt, which is a measure of how efficiently the light bulb converts electricity into visible light. The higher the lumens per watt value, the more efficient the light bulb.


How do the types of light bulbs compare?
