There is a global trend to phase out inefficient light sources like incandescent lamps from the market through legislation and voluntary measures. The objective of this paper was to find out the characteristics of the replacement lamps for incandescent lamps. Both compact fl uorescent lamps and LED lamps are energy-efficient alternatives for incandescent lamps. LED lamps have some features that make them more preferable than CFLs, like instant light output, better operation in cold conditions and longer life time. The price of LED lamps is higher than CFLs. The costs evaluation shows that both LED lamps and CFLs are economical in use even if the purchase prices are higher than the price of incandescent lamp.
