Explanation:

LEDs, or Light Emitting Diodes, have been in public use a lot longer than Compact Fluorescent Lamps, or CFLs. These are the tiny diodes that light up to indicate that something is on, or blink to attract attention. CFLs are just modified versions of the common fluorescent lamp, to achieve lower energy costs, and to fit with the slot type of the common incandescent bulb. Initially, these two light sources were used for different applications, as LEDs did not produce enough illumination for a decent light source, while CFLs were too big and too fragile to be used as indicators. However, in recent years, developments in LED technology make it a viable light source.
