Working of a fluorescent tube
We all use tube lights or fluorescent lamp in our house. It is actually a gas discharge lamp that uses electricity to excite mercury vapor
The excited mercury atoms produce short wave ultra violet light that then causes phosphor to fluoresce , producing visible light. A fluorescent lamp converts electrical power into useful light more efficiently than a incandescent lamp.
The fixure is because it requires a ballast to regulate the current through the lamp. Because they contain mercury, many fluorescent lamps are classified as hazardous waste.
