The modern market of lighting products offers a great choice of energy-saving lamps of different manufacturers with various lighting characteristics and of a large range of prices. <...> It is necessary to 85 етник ОелАУ, 4(67), Аут 2017, http://dx.doi.org/10.15217/48484 compare lighting options in order to evaluate whether they meet the declared characteristics and to identify the correspondence between the price and the quality of manufactured products. <...> The main criterion of the optimal choice of energy-saving lamps is the ratio of luminous flux to power and the cost of the lamp. <...> The lamps of three models: Camelion, Kosmos and Navigator with the power of 15 W were taken to evaluate the declared characteristics. <...> To compare the declared characteristics of the lamps mentioned above luminosity, power consumption, and run-up time at U = 220 W were measured. <...> Besides, luminous flux, luminous intensity, relative luminous flux and luminous efficiency were calculated. <...> Moreover, the deviation of the calculated luminous flux and relative luminous flux from nominal indicators were calculated. <...> Based on these results the deviation of the average calculated luminous flux from the nominal luminous flux was defined. <...> Navigator 2700K lamps have the biggest average deviation from the nominal one and it is 708.18 lm, but Kosmos 6500K lamps have the smallest deviation that equals 302.97 lm. <...> Besides, the deviation of the average relative luminous flux from the nominal relative luminous flux was measured. <...> The calculation of the correlation coefficient was made depending on the luminous flux and the lamp power. <...> Navigator 6500K lamps have the greatest dependence between the analyzed measures, Camelion 2700K lamps have the smallest dependence. <...> Taking into account the results of the calculations we can come to the conclusion that Kosmos 2700K lamp is the most optimal lamp for a customer, as its relative luminous flux equals 0,702 lm (Wrub). <...> Besides, we can add that the price of the compact fluorescent lamps is not the indicator of their correspondence with the declared lighting characteristics. <...> Key words: energy-saving lamps, price - quality, luminous flux, relative luminous flux. . <...> Для оценки заявленных характеристик были приняты лампы трех марок: Camelion, Космос и Navigator, мощностью 15 Вт, все <...>
