Fluorescent lamp
A fluorescent lamp or fluorescent tube is a gas-discharge lamp that uses electricity to excite mercury vapor. The excited mercury atoms produce short-wave ultraviolet light that then causes a phosphor to fluoresce, producing visible light. A fluorescent lamp converts electrical power into useful...

Svetlina AD (Stara Zagora)
Founded in 1949 in Stara Zagora, this plant produces vehicle lamps, ship projectors and many more. It also produces a variety of street lams, the most popular models of which are 36.9.900.094, 36.2.900.101 and 36.2.900.103. An interesting fact is that these lamp models survived for two decades before being replaced with newer, but (as reported by independent specialists in the field of lighting) inferior street lamps, produced by Hit Lighting - Bulgaria. Svetlina's lanterns are bigger and heavier than the Hit Lighting ones. However, they also have bigger refractors, thus spreading light more efficiently. In addition they have an original design, whether the lanterns of Hit Lighting look very similar to the current lanterns of other manufacturers, e.g. General ElectricGeneral Electric
