  5. Lumen (unit) - Wikipedia

    en.wikipedia.org/wiki/Lumen_(unit)

    Lamps used for lighting are commonly labelled with their light output in lumens; in many jurisdictions, this is required by law. A 23 W spiral compact fluorescent lamp emits about 1,400–1,600 lm. [4] [5] Many compact fluorescent lamps and other alternative light sources are labelled as being equivalent to an incandescent bulb with a specific ...

    A standard 100 watt incandescent light bulb emits approximately 1700 lumens in North America and around 1300 lumens in 220 V areas of the world. See luminous efficacy for the specific efficiency of various types of electric light sources.

  7. Luminous flux - Wikipedia

    en.wikipedia.org/wiki/Luminous_flux

    Luminous flux (in lumens) is a measure of the total amount of light a lamp puts out. The luminous intensity (in candelas) is a measure of how bright the beam in a particular direction is. If a lamp has a 1 lumen bulb and the optics of the lamp are set up to focus the light evenly into a 1 steradian beam, then the beam would have a luminous ...
