Compact fluorescent lamps (CFLs) now must meet minimum performance standards.
Our 2009 and 2011 tests showed big variations in light output and useful life between the best and worst CFLs ... and now the Energy Efficiency and Conservation Authority (EECA) has introduced minimum performance standards (MEPS) for these light bulbs.
All general-purpose CFLs must pass requirements for energy performance, light quality, bulb durability, mercury levels and their impact upon the country's electricity networks. There are also packaging requirements, which we reported on in July 2012.
New stock must be MEPS compliant, but existing stock (as of October 2012) can still be sold. The new MEPS requirements will weed out the worst performers but not identify the best. We recommend buying the better models from our tests.
We are currently conducting a new CFL test. The results will be published in May.
