In a few days, a law, passed under the Bush administration, will take effect, banning the manufacture or sale of incandescent light bulbs, 60 watts or below. Ah, but there is an alternative.
A new company plans to continue manufacturing and selling "rough service incandescents," which aren't covered in the ban. Rough service bulbs are meant to be used in high vibration areas, such as subways. They have additional wire within the glass enclosure that protects and supports the filament. So, they last 12 times longer than the traditional bulb.
They are also cheaper than LEDs and cheaper and safer than CFLs, which contain mercury.
Until your local stores have them, here is their site.
