Frequently Asked Questions

Lux meters, also called illuminance or light meters, are devices used to measure the amount of light in a given space (eg. luminance of luminous screens).

Lux is a unit of measure used to describe the number of lumens (unit of luminous flux) falling on a square meter of a surface.

Light from a given light source passes through the optical filter of a Lux Meter in order to reach the photodiode inside. The first section of the optical filter imitates the human perception of brightness, increasing accuracy by blocking any ultraviolet and infrared rays that the human eye cannot see. Once through the filter, the level of light measured by the photodiode is converted to lux and displayed on the device.

A lux meter is a device used to measure the intensity of light in a specific area. It has applications in various industries such as photography, cinematography, interior design, architecture, agriculture, and other fields. Common applications for lux meters include measuring the luminance level of film and slide viewers, X-ray viewers, and other displays. Lux meters are also used to determine the intensity of luminance and to calculate film density, which is the degree of film darkening.

A typical lux meter will have a measuring range from 0 to about 200000 lx.

When measuring halogen or incandescent light, Lux Meters have an extremely low margin of error, oftentimes less than one percent making them extremely accurate devices. Because Lux Meters are typically calibrated for incandescent light, the results are not as accurate when measuring alternate light sources (cool white fluorescent lights, metal halide, etc.).

There are several important benefits of using a lux meter, including extreme accuracy, fast measurements, compact design, ease of use, and matching human perception of spectral brightness. Lux meters provide precise and reliable measurements of light intensity, making them ideal for applications where accuracy is critical, such as in photography and cinematography. They are also designed to be fast and easy to use, allowing users to quickly measure lighting levels in a given space or environment. The compact design of many lux meters makes them portable and easy to carry, making them ideal for use in the field. Additionally, many modern lux meters are designed to match the human perception of spectral brightness, allowing for more accurate measurements that are more closely aligned with how the human eye perceives light.

When choosing a lux meter, there are several features to consider to ensure that it meets your needs. Some important features to consider include: Measurement range: Consider the range of light intensities that the lux meter can measure. If you need to measure very low or very high levels of light, make sure the meter is capable of measuring in that range. Accuracy: Look for a meter with a high level of accuracy, particularly if you are working in an industry where precise measurements are critical. Spectral response: Check that the meter's spectral response matches the type of lighting you will be measuring. Some meters are designed to measure specific types of light, such as incandescent, fluorescent, or LED. Display: Look for a meter with a clear and easy-to-read display. Some meters have a digital display, while others use an analog dial or needle. Data logging: If you need to record measurements over time, look for a meter with data logging capabilities. This will allow you to track changes in light intensity over time and analyze trends. Ease of use: Consider how easy the meter is to use and whether it has features such as one-hand operation or automatic ranging that can make measurements easier and more efficient. Price: Lux meters can vary in price, so consider your budget and the features you need when selecting a meter.

Did You know?

Lux Meters – devices used to measure the amount of light in a given space – are critical devices used in determining adequate architectural lighting. The most common types of architectural lighting (ambient, task, accent and decorative lighting) are seen in environments all around you. Analysis of architectural lighting is used to determine how natural or electric light can best serve human needs. Lux meters are able to efficiently measure and provide quick data on how effective provided lighting is, especially in settings where this light is needed to serve a fundamental purpose (lab environments, doctor’s offices, school classrooms, engineering/manufacturing facilities, etc.). Lux Meters measure in a unit of measure called “Lux”, which describes the number of lumens (unit of luminous flux) on a square meter of a given surface. When measuring, they typically have a range of measurement around 0 to 200000 lux with a margin of error less than one percent. Lux Meters are best at measuring incandescent and halogen light. In order to provide fast measurements with extreme accuracy, Lux Meters match the human perception of spectral brightness. They are simple yet powerful tools, making them a perfect user friendly addition to any lab environment or project.
