LED Lumen Maintenance and Photometric Degradation Analyzer
Leave a Message
Determining LED lifetime represents a critical challenge for manufacturing operations. The LS822 lumen maintenance and photometric degradation analyzer is engineered in accordance with LM-80 standards. This system records flux versus time data and exports to Excel format. Professional LED design and research engineers can perform life prediction calculations following data analysis.
Flux versus time testing requires integration with an integrating sphere of appropriate dimensions. The aging and light attenuation test system is applicable to LEDs, LED modules, LED bulbs, and other LED luminaires.
