In this case, we can actually Blame Bush for signing the stupid legislation
(Fox Salt Lake) The incandescent light bulbs that have been in homes for decades are being phased out in favor of higher-efficiency bulbs, and the older bulbs took another big step towards obscurity this week.
Last year 100-watt incandescent light bulbs disappeared. This year, it’s 75-watt. Next year, 60- and 40-watt bulbs will get the ax.
That doesn’t mean it’s illegal to use the older incandescent bulbs. They’re still around, but not being manufactured anymore.
They aren’t technically banned, but, in order to meet the strict guidelines, incandescents would necessarily be much more expensive. But, hey, we’re keeping the world from boiling or something.
