Government will ban the import of ordinary incandescent light bulbs with effect from 1 January 2016, in an effort to save up to 200 MW of power by replacing them with energy-saving bulbs (compact fluorescent lamps – CFLs). CFLs use up to 75% less energy than ordinary bulbs. However, CFLs contains mercury, which is toxic, making them problematic in Zambia, which has a poor garbage collection system. CFLs are safe as long as they remain unbroken.
