What is an Illuminance Meter?

An illuminance meter, also known as an illumination meter, light meter or lux meter, is a specialized instrument used to measure the amount of light that falls on a surface. It provides readings in lux (lx) or foot-candles (fc), helping users evaluate lighting conditions for various applications, such as workplace safety, photography, architectural design, and industrial lighting assessments.

Modern illuminance meters come in different types, including spectral illuminance meters, which can analyze light across different wavelengths for precise measurement, and standard lux meters, which provide general light intensity readings. Some advanced models also feature data logging, multiple measurement modes, and bluetooth connection, making them suitable for scientific research and professional applications. Linshang latest LS330 spectral illuminance meter has almost all of the above functions, and is suitable for a variety of applications.

Whether for ensuring compliance with lighting standards, optimizing energy efficiency, or enhancing visual comfort, an illumination meter is an essential tool for accurate and reliable light measurement.

Types of Illuminance Meters

Illuminance meters come in various types, each designed for specific measurement needs. The table below provides a comparison of different types of illuminance meters:

Type	Description	Key Features	Applications
Standard Illuminance Meter (Lux Meter)	Measures general light intensity in lux or foot-candles.	- Basic light measurement - Compact and easy to use - Affordable	- Indoor and outdoor lighting assessment - Workplace and office lighting compliance
LS330 Spectral Illuminance Meter	Measures light intensity across different wavelengths, providing spectral data.	- High precision - Measures color temperature & spectrum - Cost-effctive	- Normal and plant modes - Data logging - LED and OLED lighting analysis
LS331 Black Light Meter	Measures ultraviolet (UV) light intensity, often used for UV-A applications.	- Specialized for non-destructive testing (NDT)	- Magnetic Particle Testing -Penetration Testing

Each type of illumination meter serves a specific purpose, whether for basic lighting assessments, precise spectral analysis, or UV light measurement. Choosing the right illuminance meter depends on the specific needs of the application.
