For every CFL you install, you’ll save around $30 in electricity costs over the bulb’s lifetime. But the bulky ballast, which sits between the threaded end and the glass, prevents the bulb from being used in common fixtures such as recessed lighting and desk lamps. GE miniaturized the electronics in the ballast, so the bulb looks more like the lightbulb we’re used to and fits almost anywhere an incandescent can go. The new 15-watt bulbs, with light output equivalent to a 60-watt incandescent, should last 8,000 hours.
