[Michael Siminovitch, a self-described C.F.L. advocate and a professor and director of the California Lighting Technology Center at the University of California, Davis] said the technology exists to create C.F.L.s that are comparable to incandescent bulbs. “They can be configured and made today with great color,” he said. “They can also be dimmed. They can also be put together in such a way that they last for a very long time.”
