Save money on energy and experience full brightness the moment you flip the switch. Unlike other CFLs, GE energy smart Bright from the Start CFLs feature a capsule on the inside that provides light instantly. As the GE energy smart CFL warms to its full brightness, the halogen capsule turns off. After full warm up the GE energy smart Bright from the Start CFL performs as efficiently as a regular CFL, using 75% less energy and lasting 8 times longer than a regular incandescent bulb. These bulbs provide the same light as soft white bulbs in a similar shape while using fewer watts, helping you save money on energy.
