Many CFLs can fit in the existing incandescent light fixtures.Compared to incandescent lamps of the same luminous flux, CFLs use less energy and have a longer rated life. In the United States, a CFL can save over US$30 in electricity costs over the lamp’s lifetime compared to an incandescent lamp and save 2000 times their own weight in greenhouse gases. The purchase price of a CFL is higher than that of an incandescent lamp of the same luminous output, but this cost is recovered in energy savings and replacement costs over the bulb’s lifetime.CFLs radiate a different light spectrum from that of incandescent lamps. Improved phosphor formulations have improved the subjective color of the light emitted by CFLs such that the best ’soft white’ CFLs available in 2007 are subjectively similar in color to standard incandescent lamps.// HistoryThe compact fluorescent lamp was invented by Ed Hammer, an engineer with General Electric in response to the 1973 oil "
