Instrument Overview: LISUN LMS-6000L Brightness Tester
The LISUN LMS-6000L is a portable, high-accuracy device designed for field and laboratory measurements. It offers an impressive luminance range of 0.1–500,000 cd/m² with ±0.1 cd/m² accuracy, making it suitable for testing a broad spectrum of lighting products and display screens. The instrument provides a comprehensive suite of photometric and colorimetric parameters, including:
• Luminance (cd/m² and fL)
• Correlated Color Temperature (CCT)
• Chromaticity coordinates (x, y)
• Deviation from the blackbody locus (Duv)
• Color Rendering Index (CRI, Ra)
• TM-30 color fidelity and gamut indices (Rf, Rg)
• Color purity and dominant wavelength
• Peak wavelength and spectral distribution
These measurements offer a holistic view of a light source’s performance, aiding in product development, quality control, and regulatory compliance.
Experimental Setup and Measurement Methodology
To demonstrate the LMS-6000L’s capabilities as a brightness tester, we tested various light sources:
• LED Bulbs (Warm White, Cool White)
• Flat Panel Lights
• RGB LED Strips
• TV Screens (LCD, OLED)
Each sample was placed in a controlled environment to minimize external light interference. Measurements were taken at a fixed distance, ensuring consistent angular capture for reliable results.

Discussion
The results illustrate the LMS-6000L’s effectiveness as a brightness tester across different lighting technologies. The warm white LED, for instance, displayed a high brightness value with moderate CRI, suitable for residential applications. Meanwhile, the OLED TV screen achieved outstanding color rendering (CRI 98) and near-perfect gamut coverage (Rg 103), indicating its suitability for high-end visual displays.
The LMS-6000L’s capability to measure Duv helps manufacturers fine-tune LED spectra to minimize perceptual color shifts, while TM-30 indices provide a more detailed view of color accuracy and saturation than traditional CRI metrics. The instrument’s broad luminance range makes it adaptable to dim ambient lights and ultra-bright displays alike.
Conclusion
The LISUN LMS-6000L Portable CCD Spectroradiometer is a powerful, versatile brightness tester that excels in evaluating LED lights, flat panels, and display screens. Its wide range of photometric and colorimetric measurements enables precise analysis and optimization of light source characteristics, making it an indispensable tool for researchers, manufacturers, and quality control engineers. https://www.lisungroup.com/news/technology-news/comprehensive-analysis-of-led-and-display-brightness-using-lisun-lms-6000l-portable-ccd-spectroradiometer.html
