Abstract
Presented results of studies of the spectral characteristics of retrofit lamps of the A60 type form factor include correlated color temperature and spectral distribution of radiation flux density during the burning time of the lamps. Changes in the spectral characteristics of the studied LED retrofit lamps are analyzed over a period of 6000 hours and the proportion of the blue component of the lamps under study is determined. Measurements of lamp parameters are carried out using a photocolorimetric measuring setup at a network voltage of 220 V. When calculating the chromaticity coordinates and color rendition of the lamps under study, the spectroradiometric method is used. Research results show the feasibility of replacing traditional lamps by LED light sources with parameters favorable to humans.
