Energy Tip
of the Day!

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 At present LED Lamp technology has improved rapidly end in parallel the price of LED lamps have come down to  an affordable Scale for the domestic consumer. Sri Lanka has already introduced performance stety and Minimum Energy performance  standers (MEPS) for LED Lamps introduce for which satisfy MEPS.
