Replacement of incandescent lamps with energy efficient lamps in developed and developing countries

All over the world energy inefficient incandescent lamps are used in great numbers. Replacement of these inefficient lamps with energy efficient lamps can save energy and reduce energy bills for the consumers. This work discusses how much energy can be saved by replacing incandescent lamps used for task lighting with energy efficient lamps. This replacement results in cost savings and reduction of CO2 emission. The purpose of the work is to assess the feasibility of the energy efficient lamps compared to the existing incandescent lamps. The performance of the compact fluorescent lamp (CFL) and light emitting diode (LED) lamps has been measured mainly for task lighting and then compared with that of the incandescent lamps. The performance of 60 W incandescent lamps has been compared with the performance of CFLs of power 11 W to 15 W and LED lamps of power 4 W to 13 W. The performance of these different lamps has been demonstrated through measurements made for both developed and developing countries. The measurements show that it is possible to replace incandescent lamps used for task lighting with energy efficient CFL and LED lamps have shown very promising results and they have a bright future in lighting
