This work analyzes the effect of the voltage variation in LED lamps at the luminous and power quality behavior of LED lamps which employs different topologies in their drivers. Samples are tested on 18 single-base LED lamps with an integrated control device, GLS LED bulbs, with different wattage between 6W and 18W, 6 flyback topology lamps with input filter, 6 topology lamps input filter and 6 topology lamps buck without Input filter. The methodology of the work consists in applying voltage values different from nominal ones in a step of + 5% and -5% until reaching levels of + 20% and -20%, totaling 22 levels of tension and 396 measurements. Throughout the tests, measurements of power, luminous flux, power factor, harmonic current, total harmonic distortion (THD), color temperature, color reproduction index (CRI) and luminous efficiency were made.
