Lux Meter 💡 Light Measurement App - (Brightness Meter 💡 or Light Meter app 💡) you can measure ⏱ light intensity, Lux, Candle and you can save data and share this saved file.
Lux Meter App you can find best photo light for your photos and videos.
The Lux meter 💡– Light Meter 💡 keeps the light intensity data in the context of date and time, and the frequency of receiving data can be changed if desired.
measure and record the Lightning Levelof a business, delicate lux measuring and candle, Lumen measuring. You can calculate lumen by using this app.
➡️ A foot-candle (sometimes foot candle; abbreviated fc, lm/ft2, or sometimes ft-c) is a non-SI unit of illuminance or light intensity. One foot-candle represents "the illuminance cast on a surface by a one-candela source one foot away."[citation needed] This unit is commonly used in lighting layouts in parts of the world where SAE units are used.
➡️ The unit foot-candle is defined as the amount of illumination the inside surface of a one-foot-radius sphere would be receiving if there were a uniform point source of one candela in the exact center of the sphere. Alternatively, it can be defined as the illuminance on a one-square foot surface of which there is a uniformly distributed flux of one lumen.
➡️ Thus one foot-candle is equal to one lumen per square foot or approximately 10.764 lux. In practical applications, as when measuring room illumination, it is very difficult to measure illuminance more accurately than ±10%, and for many purposes it is quite sufficient to think of one foot-candle as about ten lux as is typically done in the lighting industry.
➡️ In the lighting industry, foot-candles are a common unit of measurement used to calculate adequate lighting levels of workspaces in buildings or outdoor spaces. Foot-candles are also commonly used in the museum and gallery fields, where lighting levels must be carefully controlled to conserve light-sensitive objects such as prints, photographs, and paintings, the colors of which fade when exposed to bright light for a lengthy period.
➡️ The lux (symbol: lx) is the SI derived unit of illuminance and luminous emittance, measuring luminous flux per unit area. It is equal to one lumen per square metre. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface..
➡️ Luminance
Illuminance is a measure of how much luminous flux is spread over a given area. One can think of luminous flux (measured in lumens) as a measure of the total "amount" of visible light present, and the illuminance as a measure of the intensity of illumination on a surface.

Light Meter: Measure Lumen, Intensity & Lux Meter APK: questions and answers
Can I install this APK over the version I already have?
Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.
Is the Light Meter: Measure Lumen, Intensity & Lux Meter APK safe?
No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is 261830719118e6bac9c7042d3a3b895f.
