What is Lightmeter?

Lightmeter is an open-source application available for Windows, macOS, Linux, Android, and iOS that functions as a light and color meter. It can accurately measure parameters like:

Color temperature of ambient light and light sources in Kelvin
Illuminance in Lux
Luminance in Candela per square meter
Chromaticity coordinates like x,y values and duv

Lightmeter uses the camera and sensors on smartphones or laptop webcams to take measurements. It can help photographers set custom white balance, assist cinematographers in color grading footage to match lighting, help lighting designers test and set up fixtures, and enable anyone to evaluate the light in their environment.

As an open-source program, Lightmeter is free to use and get started with. It provides reliable measurements compared to commercial handheld light meters. The interface is intuitive and it's easy to take multiple readings and export data. Overall it's a great alternative to buying an expensive specialty light meter.
