Abstract As a new generation of solid-state lighting sources, LED quality directly determines lighting effect, energy efficiency, and service life. Opto-electro-color parameters are the core indicators for measuring LED quality. Lumen testers, as key equipment for detecting LED opto-electro-color parameters, play an irreplaceable role in quality control. This paper takes the LISUN LPCE-2(LMS-9000)...
The high rate of development of solid-state lighting has generated the demand of precise and dependable luminous flux measurements. To develop energy-saving LED systems, the optical output, color stability, heating impacts and reality lumen depreciation have to be evaluated accurately. The most common method of this measure is one found on an integrating sphere which is an optical enclosure that i...

Abstract In the lighting industry, the photometric, colorimetric, and electrical parameters of luminaires are core indicators for measuring product quality and performance, directly influencing lighting effects, energy efficiency, and user experience. As a professional testing equipment integrating a high-precision spectral radiometer and an integrating sphere system, the integrating sphere set...
Abstract With the diversification of lighting technologies, the accurate measurement of luminous performance has become crucial for quality control and standard compliance across lighting product categories. Lumen test equipment, as the core tool for evaluating light output and optical characteristics, plays an irreplaceable role in testing energy-saving lamps, fluorescent lamps, HID lamps, cold c...
In 2019, ANSI and IESNA jointly released the ANSI/IES LM-79-19 standard, establishing a critical benchmark for the LED solid-state lighting (SSL) industry. Over five years later, in 2025, the lighting industry is once again undergoing a major transformation with the release of the latest version of the LM-79 standard – ANSI/IES LM-79-24 – jointly issued by the American National Standa...
The demand for high-quality lighting solutions has led to a significant focus on testing and standardizing various light sources, including energy-saving lamps, fluorescent lamps, high-intensity discharge (HID) lamps such as high-pressure sodium and mercury lamps, cold cathode fluorescent lamps, and LEDs. To ensure compliance with international standards such as CIE 177, CIE-13.3, CIE-84, ANSI-C78...
Introduction In recent years, the demand for high-efficiency lighting systems has increased due to global energy-saving initiatives. This trend has resulted in the widespread use of energy-saving lamps, fluorescent lamps, high-intensity discharge (HID) lamps, and especially light-emitting diode (LED) lamps. Accurate photometric and colorimetric measurement of these light sources is essential for e...
