Dual Measurement Modes: tests both illumination (lux) and luminance (cd/m2) in one device, reducing the need for multiple instruments and saving time. Backlit Display: easy to read readings in lowlight conditions thanks to a userfriendly backlit LCD screen. Sensitivity Sensor: professionalgrade accuracy with ±3% precision to support reliable measurements. Compact and Portable: pocketsized design with 30hour battery life, ideal for fieldwork and onsite checks. Practical use scenarios Photography and videography: quickly gauge scene illumination and subject luminance to set up lighting for consistent exposure and mood. Display design and evaluation: verify ambient illumination and display luminance in showrooms, galleries, and retail environments to maintain a uniform look. Field measurements: perform onsite light assessments during construction, architecture, or remote shoots with long battery life and easy portability.
