Compact fluorescent light bulbs are designed to replace standard bulbs and can fit in the existing fixtures formerly used for incandescents. Compared to general lamps giving the same amount of visible light, CFLs use less power and have a longer rated life. In the United States, a CFL can save over 30 USD in electricity costs over the lamp’s lifetime compared to an incandescent lamp and save 2000 times its own weight in greenhouse gases. The purchase price of a CFL is higher than that of an incandescent lamp of the same luminous output, but this cost is recovered in energy savings and replacement costs over the bulb’s lifetime. Like all fluorescent lamps, CFLs contain mercury. This complicates the disposal of fluorescent lamps and causes a health risk when they are broken.
So go green around the office or home and replace those old bulbs today!
