The brightness of light emitted from a mobile device’s integrated light source is measured in lumens. This measurement quantifies the total amount of visible light produced by the light source. As an example, a higher lumen value indicates a brighter light, allowing for greater visibility in dark environments.
Understanding the light output of a smartphones light is beneficial for various reasons. It assists in determining its suitability for tasks such as navigation in low-light conditions, close-range illumination, or signaling. Historically, dedicated flashlights were necessary for these purposes, but the integration of lights into mobile phones offers a convenient, albeit often less powerful, alternative.
