GE’s hybrid bulb looks like an incandescent but has the energy efficiency of a compact fluorescent (CFL). A halogen capsule instantly illuminates while the CFL warms to full brightness. The bulb lasts eight times longer than an incandescent, GE says, and the 15-watt and 20-watt models are equivalent to 60-watt and 75-watt bulbs, respectively. GE. 203.373.2211.
