Label your CFL

-- Standards in six months likely

THE Bureau of Energy Efficiency (bee) is preparing new labeling standards for cfls (compact fluorescent lamps) based on light output. Like other consumer electronics such as refrigerators, air-conditioners and fans, cfls would also be given star ratings--five stars would denote maximum efficiency.

The new standards would be voluntary.

"The Bureau of Indian Standards warrants the minimum light output of cfls must be 45 lumen per watt consumed," a senior bee official said. In India, cfls sold have a lumen efficacy of 45-58 lumens per watt. It is possible to have cfls with light output at 67-70 lumens per watt, he added.

It will take another six months to bring about the standard. When set, they would put all the brands on the same platter. "Currently," the official added, "a well known brand might sell more than a lesser known brand even though the latter may have a higher output."

Meanwhile, the cfl bulb manufacturers are keeping their fingers crossed. "The industry would be happy if the upper limit for lumen efficacy is kept at about 65 lumen per watt," said Shyam Sujan, secretary general of Electric Lamp and Component Manufacturers' Association of India.
