How does a cfl bulb works?
Compact Fluorescent Light bulbs (CFLs) use fluorescent technology to produce high-quality, energy-efficient light that lasts far longer than typical incandescent bulbs. When power is turned on, an electric current is created inside the tube and runs between two electrodes. This current causes the encapsulated mercury to vapourize. The mercury vapour gets “excited” causing the electrons to hit the edge of the tube; in turn lighting the phosphors. This is what makes the bulb glow.
