SEATTLE -- Light bulb manufacturers will cease making traditional 40 and 60-watt light bulbs -- the most popular in the country -- at the start of 2014.
This comes after the controversial phasing out of incandescent 75 and 100-watt light bulbs at the beginning of 2013.
In their place will be halogen bulbs, compact fluorescent bulbs, LED bulbs and high efficiency incandescents -- which are just regular incandescents that have the filament wrapped in gas. All are significantly more expensive than traditional light bulbs, but offer significant energy and costs savings over the long run. (Some specialty incandescents -- such as three-way bulbs -- will still be available.)
The end of old light bulbs will likely anger some consumers that are already faced with higher prices for a variety of goods. But it will also tick off tea party activists since the ban is the result of the final phase of government-mandated efficiency standards.
The rules were signed into law by President George W. Bush in 2007. They are designed to address gross inefficiencies with old light bulbs -- only 10% of the energy they use is converted into light, according to the Environmental Protection Agency, which has a handy fact sheet about the changes. The rest is wasted as heat.
But the rules have drawn fire from a number of circles -- mainly conservatives and libertarians who are unhappy about the government telling people what light bulbs they can use. They argue that if the new ones really are so good, people will buy them on their own without being forced to do so.
