Many users assume that measuring illuminance is as simple as turning on a lux meter and reading the displayed value. In reality, improper measurement techniques, incorrect sensor positioning, unsuitable measurement timing, and environmental factors can all lead to significant errors. This article explains the most common mistakes when using a digital lux meter, why they occur, and how to avoid them to obtain accurate and reliable illuminance measurements.

The accuracy of a digital lux meter depends on more than just the instrument itself. Sensor quality, light source characteristics, measurement angle, ambient temperature, calibration status, and operating methods can all influence measurement results. This article explains the key factors affecting lux meter accuracy and provides practical tips to minimize measurement errors for more reliable illuminance testing.

Illuminance is one of the most important lighting parameters used to evaluate how much light falls on a surface. It is widely applied in lighting design, architecture, industrial inspection, photography, horticulture, and workplace safety. This article explains what illuminance is, how it is measured, its unit (lux), influencing factors, common standards, practical applications, and how it differs from luminance and luminous flux.
