In protecting environment chrysanthemum's production, the artificial illumination type used to induce the photoperiod, affects the growing and development of plants, as well the electric power consumed in this process of production. The most useful illumination type is by filament. Today, new artificial illumination technologies have been studied to reduce the electric power consumption. This work has been development in a commercial greenhouse with four varieties. The preliminary results have showed that the utilization of discharge lamps does not affect significantly the flower's development considering the weight and presence of flower bud. In the analyzed period, the reduction on power electricity consumption was 60,13% on the sodium-vapor lamp, 41,66% on the mercury-vapor lamp, 60,52% on the fluorescent tube lamp and 50,32% on the compact fluorescent-integrated lamp in comparison with the incandescent lamp that nowadays it is used. It shows the high intensity discharge technology (HID technology) has saved more electricity than the incandescent lamp.
