Energy star rated compact fluorescent Lamp (CFL) should be the choice in household lighting applications
From the extraordinary Gazette notification No. 1611/10 of July 22,2099, the display of the Energy Label on every CFL was made mandatory. The energy label consists of star rating which varies from 1 star to 5star higher the number of the star greater the energy efficiency of the CFL. Accordingly CFLs having an energy label with 5 star are most energy efficient compared to the CFLs having 1star to 4star rating. By repacking a 1star CFL with 5star CFL with 5-7 watts lower in wattage the same light out put can be gained. Purchasing a CFL with 5 star rating about 5-7 watts can be cut down

Sri Lanka has already introduced performance stety and Minimum Energy performance standers (MEPS) for LED Lamps introduce for which satisfy MEPS.
