- Fluorescent tubes glow white because of a fluorescent coating inside the glass tubing.
- The coating contains a white powder called phosphor, which emits visible light when it absorbs ultraviolet (UV) energy waves.
- When electricity enters a fluorescent light bulb (CFL), the mercury and argon fumes inside the bulb produce UV light.
- This UV light reacts with the phosphor coating to produce the white, visible light you see when you turn on a CFL.
