   Incandescent light bulb ... There is currently interest in banning some types of filament lamp in some countries, such as Australia planning to ban standard incandescent light bulbs by 2010, because they are inefficient at converting electricity to light.Sri Lanka has already banned importing filament bulbs because of high use of electricity and less light.
