From 1 September, Europe will take another fundamental step to reduce the energy consumption of lighting in all buildings: in fact, the call for halogen light bulbs will start. Not all of them will be forbidden, to be precise. Progressively, these will be the traditional pear-shaped, non-directional glass bulbs in energy class D, while other types of halogen lamps will continue to be accepted, such as those with R7 and G9 connections, provided that are at least in energy class C. The novelty refers to Regulation no. 244/2009 of the European Commission on the eco-compatible design of household lamps, in turn linked to the EUP (Energy Using Products) directive 2005/32 / EC. In fact, the call was scheduled for September 1, 2016, but then the EU institutions had decided to postpone the ban to 2018, so as to wait for the full technological development of LEDs, which in a couple of years would have achieved efficiencies even higher at lower costs. This will complete the exit from the market of the most inefficient light bulbs, started in 2009 with the stop to the sale of old incandescent bulbs of more than 100 watts and continued in stages in the following years, until the elimination of incandescent bulbs from 25 -40 watts in 2016. With regard to halogens, prohibited products may be marketed until stocks are exhausted.
