How To Measure Lumens With Phone

See How To Measure Lumens Below:

Lumens are the measurement of the total energy output from a source of light. Luckily for us, there is a relatively simple way to determine and translate the strength of lumens. The reason behind using lumens to measure the light output for lights is because it has been determined that it is the best way to measure how efficient the lightbulb is.

A 100 Watts Incandescent Bulb Gives The Same Amount Of Lumens As 23 Watts Cfl.

Not that watts are bad, but they measure energy use, not light output. Candelas measure how intense or focused a light output is. (a lot of those searchlight have very inflated cp figures).

Watts Is A Measurement Of The Power Consumed By A Product.

Please note that light meter app is not a replacement for a professional device and should be used for private purposes only. Jonathan hardis made an excellent answer on measuring lumens in general. Key takeaways about flashlight brightness.

Input Is Watts But Output Is Lumen.

That tells you the total light energy. There are two oft confused measures of light. One is lumens which is luminous output.

Even The Efficiency Of A Light Bulb Is Defined In Lumens/Watt (Output/Input.

It is the output of a bulb rather than input. In this tutorial, you'll learn how to turn your phone into a reliable light meter. Or you can mention candlepower.
