I agree, CFLs and LEDs may have their advantages - but the "switch all your lights and save lots of money" campaigns are like saying "Eat only bananas and save lots of money!" It is indeed a "ban": Yes, energy efficient halogen incandescent replacements are allowed, but still have some constructional and appearance differences, a whiter light output etc compared with regular bulbs, apart from costing much more for the small savings, which is why neither consumers or governments really like them, since they have been around for a while now without being sold much. No light bulbs should be banned: There is no present or future shortage of energy sources for electricity justifying telling what paying consumers can use, especially since the overall USA energy savings from light bulb regulations are less than 1% anyway, based on the US Dept of Energy's own statistics ( ) -remember the politicians keep including non-incandescent street and industrial lighting in the usual high US usage percentages quoted. Much greater, and much more relevant, energy waste savings arise from effectively organized electricity generation and grid distribution, and from reducing the unnecessary use of appliances: rather than from stopping people in their choice of what appliance to use.
