Power-saving compact light bulbs as a substitute for traditional light bulbs are an unsurpassable example of certain and rapid returns on energy efficiency and its costs. Nevertheless, thanks to the greater investment costs for their purchase, they have not yet replaced classic light bulbs in all the places where it would make sense. The European Enerlin project, in which the SEVEn Centre is involved, has decided to focus on the informative and marketing support of powersaving light bulbs among the general public, specifically through a series of educational articles, leaflets and printed materials, internet presentations and suchlike.
