Starting in 2011, GE Lighting will market an incandescent-shaped light bulb that combines the instant brightness of halogen technology with the energy efficiency and longer rated life of compact fluorescent (CFL) technology. The halogen capsule inside GE's new hybrid halogen-CFL bulb comes on instantly, allowing the bulb to operate noticeably brighter in less than a half a second. The capsule shuts off once the CFL comes to full brightness. First to launch will be 15W and 20W hybrid halogen-CFL bulbs that are considered viable replacements for 60W and 75W incandescent bulbs, respectively.
