Light meters, sometimes referred to as lux meters, are instruments that measure light levels or light pollution. You can find out more in our complete guide to light meters.
Light can be measured in different ways with different light measurement instruments:
Light meters usually return measurements in Lux (in Europe), foot-candles (in the US), or both. Typical models are handheld and feature an integrated light sensor or a sensor connected by a lead.
Light meters 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.
They are also a key piece of light measurement 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.
