During the energy crisis of the 1970s, the first real efforts were initiated to begin developing a more efficient light source which could replace the traditional incandescent lamp. It was recognised that the relatively small improvements that had taken place in incandescent lamps during the previous four decades were not enough, and there was potential for replacing it with one of the other newer lamp technologies.
The main focus in Europe was on miniaturising fluorescent lamps and equipping them with compact integrated ballasts, while the Americans initially focussed on miniature self-ballasted metal halide sources. Additional efforts were directed by both continents towards miniaturised electrodeless induction lamps.
Ultimately it was the compact fluorescent approach that won, thanks to the timely development of a new series of phosphors that could endure the higher thermal loadings in small lamps, and the parallel development of miniaturised ballasts. The advantages of the resulting lamps were so significant that they also led to the introduction of the large family of non-ballasted compact fluorescent lamps, intended directly for use in new luminaires having remote control gear.
