Production or incandescent lamps, which is India's most widely used mode, was 600 million pieces in 1997 compared to 8 million in 1947. The efficiency of these lamps is 15 lumens/W as compared to 68 lumen s/W for f'lu orosccn t Iuhcs. To cut down the peak demand on the supply of electrical power. economical compact tluoroscent lamps (CFL's) arc perl'cct substi tute for incandescent lamps - scoring well on light output and physical dimension, and saving abou t 75 - ~W% of the power consumed for the same light output. CFL is also an environmentalist's delight a-; it generates about 75% less heat thereby creating a cool ambience. The life of CFL is 10 times higher than that or ordinary bulb. CFL's are broadly divided into two categories, Retrofit and non -retrofi t. The !'ormcr is a direct replacement and can be fitted in the nrigtnal lampholder of GLS while in the non-retrofit Sourn•: l:'conom1c Times. .J March 1998 category the lamp has built-in starter but the ballast is housed 111 a luminaire of suitable design. To consumers, economy from CFL is highly attractive in that the saving in electricity bill for one to one and a half years will pay back the original investment. The following table will give a better idea of the energy saving of CFL vis-a-vis incandescent lamps of different wattages.

With rising incomes and better avai lability of domestic appliances, consumption of electrical energy is increasing at a much higher rate than the overall growth of electrici ty consumption in the country, or even the economic growth of the country. Under such circumstances, it is necessary that energy consumption by these appliances should be closely monitored and constant auempts should be made to upgrade them. 13
