Replace your regular 60-watt incandescent light bulbs with these 14-watt CFLs. Measuring 5 inches, they provide the same amount of soft white light as 60 watt incandescents (often slightly more) and last at least five times longer (about 8,000 hours). Sylvania claims one compact fluorescent bulb pays for itself with lower electricity costs after only five months. This bulb is safe for both outdoor and indoor use.
