During the 1930´s the hot potato for the Swedish lighting associations were how to create the most suitable light for every situation, either for industries, offices or homes. The light bulb were the most frequently used source of light but due to limitied luminous intensity, big halls sometimes required up to hundreds of light bulbs to produce the right amount of light. Two kinds of different lights, by different reasons, can be titled the predecessors of the fluorescent lighting during the 1930´s: The volfram-filament tube light due to its estetic similarities and the electric discharge (mercury- and sodium-) lamps due to its technical resemblance. Even though they came in quite wide use (the volfram tube in public halls (e. g. cinemas and public baths) and the discharge lamp in the industry) none of them could provide a light that combined efficiency in both light and cost.This essay deals with the predecessors as well as the introduction of fluorescent lighting in Sweden 1940-1945 primarily as a consequence of todays non existing historic knowledge about this modernist invention. By analyzing articles and advertising issued by the Swedish journals Elektricitetens rationella användning and Tidskrift för Ljuskultur 1930-1945 this thesis answers questions about how, why, when and where the lamp industry came to bring the new kind of light on the market.The research concludes that fluorescent lighting was introduced in almost every environment except for the homes, even though the Swedish lighting associations believed it to be the future also for the homes. The prospects for the new light source were without exeption positive and promising and in both articles and advertising it was talked about as the ?artificial daylight?. The light fittings were made different depending on the purpose of the room. Esthetic as well as functional reasons together with the extracted shape of the lamp made the designers make fittings that differentiated heavily from the fluorescent light fittings we are used to see today.
