This report examines the same LED lamp models covered in CALiPER Report 20.4 but focuses more on the chromaticity maintenance of individual samples rather than the lamp model averages that were emphasized in CALiPER 20.4. This approach was taken to facilitate a classification of the chromaticity shift modes (CSM) for each sample and a comparison of CSMs across all samples of a particular lamp model and between lamp models with similar characteristics. In general, samples of the same PAR38 lamp model usually exhibited the same chromaticity shift behavior, and there were similarities in chromaticity shift trends between lamp models with similar LED packages. However, the timing of different chromaticity shifts varied somewhat between lamp models and appears to depend upon lamp design, characteristics of the LED packages used in the lamp model, and lamp operational conditions.
