| Features | - Measures and evaluates parameters such as radiation spectrum, illuminance, color temperature, chromaticity coordinates, and color rendering index (CRI) for LED lighting and various lighting modules.
- Ideal for on-site measurement and assessment of lighting environments in locations such as libraries, shopping malls, schools, factories, and street lighting projects.
- Analyzes chromaticity coordinates, color gamut, uniformity, CRI, and radiation spectrum performance of TVs, monitors, and projectors.
- Detects light source performance and white balance parameters in camera products.
- Evaluates the performance of eye-protection lamps and outdoor lighting conditions.
- Assesses uniformity, illuminance, CRI, color temperature, and spectral consistency of lighting sources in standard light boxes.
- Features a 400–700 nm spectral test range with multiple functional parameters, simple operation, stable performance, and excellent cost efficiency.
- Compact and portable design with a detachable measurement probe, Type-C and Bluetooth interfaces, and wide application versatility.
- Includes built-in spectra for standard light sources such as D65/A/C/5000K, allowing convenient comparison between test and reference light sources.
- Offers multiple measurement modes—single, average, continuous, and flash—suitable for various testing scenarios.
