Fluorescent Tubes

Fluorescent tubes are low pressure mercury discharge lamps, in which light is produced predominently through fluorescent powder activated by the discharge of ultra violet energy.

The lamp, generally with a tubular-shaped glass bulb and a sealed electrode for each terminal, contains low preassure mercury vapour and a small amount of inert gas for ignition and arc regulation.

The glass bulb inner surface is covered by a luminescent (fluorescent powder of phosphorous) whose composition determines the amount of emitted light and the lamp color temperature.

The lamp requires an auxillary equipment formed by a Ballast and starter as well as trimmer to improve the power factor.
