LED Light Bulbs

As the DOE notes in the FAQ, it’s not entirely fair to directly compare compact fluorescents to LED lights, since LED bulbs have a more directed light making them perhaps better for applications such as bedside reading lights, where you don’t want to bother a dozing partner. LEDs, due to their exceptionally long life — upwards of 60,000 hours — are als...
