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](https://uk.rs-online.com/web/c/test-measurement/environmental-test-measurement/light-meters/?applied-dimensions=4294329118) are also available. You can find out more in our [guide to light meters](https://uk.rs-online.com/web/content/discovery/ideas-and-advice/light-meters-guide).

At RS, we offer a wide range of light meters from trusted brands such as Extech, FLIR, and [RS PRO](https://uk.rs-online.com/web/c/test-measurement/environmental-test-measurement/light-meters/?applied-dimensions=4291471876). These high-quality instruments are essential for accurately measuring light levels in various environments, ensuring optimal conditions for your applications. Our light meters are available with fast delivery options to meet your urgent needs, and we also provide calibrated services to guarantee precise and reliable measurements. Trust RS for all your light measurement requirements, backed by expert support and top-notch service.

### Types of Light Meters

Light can be measured in different ways with different light measurement instruments:

- **Photometer** – measures visible light or light intensity. Light intensity can also be measured in two different ways; one way is by using a luminance meter which measures the visible energy output of a light source, or another method is by using an illuminance meter that measures the visible energy falling on an object's surface
- **Integrating sphere** - collects electromagnetic radiation from a source completely external to the optical device
- **Spectrometer** – uses the light, breaks it into its spectral components and creates a digital signal in wavelength form
- **Light Meter** – measures light levels and is the most commonly used piece of equipment

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.

### Key Benefits of a Light Meter and a LUX Meter:
- Portable and sometimes pocket-sized, they are a useful piece of equipment to have for any light measuring applications
- A meter that offers accuracy in measurement
- Easy to read displays with real-time results
