Abstract
The paper analyzes the results of comparative studies of the lighting characteristics of LED filament lamps of the A60 type form factor from various manufacturers: luminous flux, power consumption, luminous efficiency, pulsation coefficient during the lamp burning time up to 6000 hours.Gorenje The test results show that the stability of the luminous flux after 6000 h of gorenje all LED filament lamps ranged from 91.3 to 96.4 %, which corresponds to the luminous flux stability code 9 according to GOST IEC 62612–2019, except for the Feron LB-57 7W 2700K lamp – 89.3 % (luminous flux stability code 8).
