Halogens in the shape of a traditional bulb can be about 20 percent more efficient than incandescent lighting.

You can include halogens to the list of lights that can replace traditional incandescent bulbs.

General Electric on Monday announced a line of halogen lights, which are available now, in the shape of the familiar incandescent which up to 22 percent more energy efficient.

A 2007 law created mandated efficiency levels for home lighting, which is expected to lead to fewer incandescent bulbs, starting with the 100-watt incandescent next year. Governments in other countries have set similar lighting efficiency requirements, which has led to more options for efficient lighting.

Compact florescents and large LED bulbs are expected to meet the mandated efficiency levels. Halogens for general lighting or spotlights will comply with U.S. and global efficiency laws as well, GE said. It sells two-packs of the halogens bulbs for between $4 and $7.

Halogen is an incandescent technology which offers precise dimming and crisp light, said John Strainic, global product general manager of GE Lighting in a statement.
