Another complaint against compact fluorescent light bulbs (CFLs) will have to go by the wayside with the introduction of a new hybrid bulb from GE that is able to come to immediate full brightness as soon as it is switched on. As with cars, where hybrids combine the best properties of two transport technologies, hybrids are now an option for light bulbs, combining immediate brightness of halogen with the energy savings of a compact fluorescent.

GE LightbulbThe bulb itself is in a conventional incandescent-shape. Inside that is a now-familiar coil of compact fluorescent tubing. But, at the center of that is a small halogen capsule. When the light is turned on, both the halogen and the CFL come on, so that the bulb has full brightness immediately available. Once the CFL has reached its full brightness, the halogen portion automatically turns off, so that the life of the bulb is conserved.

The hybrid bulbs have an expected lifetime of 8,000 hours, about 8x as long as incandescent bulbs, and close to the expected life of regular CFLs. Additionally, these hybrid bulbs have a lower level of mercury than most currently available CFLs. The hybrid bulbs contain just 1 mg of mercury, while most current CFLs have 1.5 to 3.5 mg of mercury.

The hybrid bulbs are available for 60- and 75-watt replacement and should now be starting to appear in retail stores, with an expected price range of $5.99 to $9.99.
