Philips Halogena Energy Saver (70-watt)
Dimmable halogen light bulbs
*Est. $12 for two
Halogen light bulbs turn on instantly and can be used with dimmers, unlike many compact fluorescent light bulbs. While the Philips Halogena bulbs are more efficient and longer lasting (about 3,000 hours) than incandescent bulbs, they aren't as efficient or long-lasting as CFL bulbs (which can last 10,000 hours). Still, reviews recommend halogen bulbs for fixtures that are turned on and off often, because this doesn't shorten their life. Reviewers say that the light quality is pleasing, and that Halogena halogen light bulbs are especially good for task lights and displaying art. These energy-saving halogen light bulbs copy the style of most incandescent bulbs, and they fit medium-base, screw-in light fixtures. They use about 30 percent less energy than an incandescent (so a 70-watt halogen light bulb replaces a 100-watt incandescent).
