Abstract
The diffusion of LED lamps on the market is becoming increasingly wide and it is expected that, in a few years, they become a sort of standard de facto for lighting of houses as well as offices. As a consequence, they can be considered for replacing the incandescent bulb in the international standard for flicker measurement given that, as it is well known, this last lamp is banned from the market and hence the measurement of flicker severity is no more related with the actual annoyance caused by the light fluctuation. In this connection, this paper will investigate the behavior of several same-power LED bulbs under nonsinusoidal voltage conditions to verify if it is possible to choose a specific LED source as a reference for flicker evaluation.
