Light meters, sometimes referred to as lux meters, are instruments that measure light levels or light pollution. They are frequently used in workplaces, schools, hospitals, and public places to test if there is an appropriate amount of light within the environment. This is particularly pertinent in the workplace, as there is a responsibility that employees work in an environment with suitable lighting.
Light meters are also an essential piece of equipment when it comes to working in photography, especially when using a camera in a studio, or in ambient light. A handheld light meter is often used to determine the proper exposure for a photograph.
Budget light meters can help to perform quick checks on light intensity where more advanced models have monitoring functionality as well as the ability to record, store and transfer data. If accuracy is of the utmost concern, calibrated light meters are also available. You can find out more in our guide to light meters.
