A while back we introduced you to Plumen, the world's first designer low energy lightbulb. These CFLs in interesting shapes have just become compatible with 110V electrical systems, meaning that they can finally be used in the United States.
The bulbs are expensive at $29.95 but last eight times longer than a traditional incandescent and are so great-looking that you'll want to keep them exposed in your interiors. They are also easy to use because they fit in standard lightbulb fittings and give off a warmer quality of light than other CFLs.
If you'd like to get a hold of Plumen for yourself, you can find ordering information at the Plumen website.
