This new hybrid bulb from GE combines the instant brightness of halogen technology with the energy efficiency of a compact fluorescent. The manufacturer says the product offers eight times the life of a standard incandescent and is made with low levels of mercury. A halogen capsule inside the product comes on instantly and allows the bulb to operate noticeably brighter in less than half a second.
