Title: Color Consistency of Retrofit LED Lamps
Keywords: color shift of solid state products; LED aging; LED color co
Abstract: As it has been ever since the artificial lighting has been introduced, a lot of “unknowns” have been brought with the development of solid-state lighting. The current paper presents an investigation of the color shift of the light of LED retrofit lamps, operating at normal operational conditions for a period of three months. For description of the color consistency of the test lamps the correlated color temperature CCT and Duv and standard deviation color match SDCM have been chosen. The change of the spectra and color rendering are also estimated, CRI, CQS, GAI and TM - 30 Rf and Rg are measured and analysed.
