What is Tube Light? Tube shaped fluorescent lamp is termed as tube light. Tube light is a lamp that works on low pressure mercury.

What’s Inside a Fluorescent Tube Light? • A fluorescent lamp basically consists of a long glass gas discharge tube. Its inner surface is coated with phosphorous and is filled with an inert gas, generally argon, with a trace of mercury. • The tube is then finally sealed at low pressure with two filament electrodes each at its both ends. • These electrode filaments are used to preheat the tube and initiate a rapid conduction of electrons between the two end electrodes. The process initially requires a relatively high amount of power. Uli Sata Raid Controller M1573 Driver.
