How it's used
Although the term specifically refers to compact fluorescent lamps, it is often used as a generic label for any energy-efficient bulb in casual conversation. As LED technology has become the standard for home lighting, many people have started using the term interchangeably for LEDs, even though the underlying technology is different.
