PRLog -- Replaceable cell batteries did not stay much in demand, after the invention of the alkaline batteries which were then used to power the bicycle lights. These alkaline batteries had this great advantage of having much more storage density. At the same time, the molding techniques also started improving and the plastic molding also got refined. This resulted in a better lens optics, which made the use of light output much more efficient than it was before that time. The 1980’s was the period when the lighting market moved towards globalization. Many brands present in different parts of the world gradually disappeared from the scene, and the American, Japanese and German products became popular all over the world.
