Abstract

In accordance with the Energy-using Products Act (Energiebetriebene-Produkte-Gesetz - EBPG), which implements EU Regulation 244/2009, the phasing-out of several types of incandescent bulbs and their replacement by energy-saving lamps started on 1 September 2009. Energy-saving lamps emit a different spectrum than incandescent bulbs. The spectral composition of the optical radiation (UV, Visible and IR) generated by energy-saving lamps such as compact fluorescent lamps (CFLs) and LEDs varies largely. These lamps usually have a higher blue light content than incandescent bulbs. They also tend to have a discontinuous spectrum which might interfere with colour reproduction.

Against this background the SSK has prepared a statement including a health evaluation of the types of lamps currently used for indoor lighting.

Modern lamp types reliably comply with radiation protection requirements at the distances relevant in practical applications. This evaluation results from measurements conducted specifically for the purpose of this statement and is in line with the findings of national and international studies (such as [BfS 2009], [Nadakuduti 2010]).

The quality of the light generated by CFLs does not differ fundamentally from the fluorescent lamps which have been in use for decades. For that reason, the SSK sees no cause to issue specific recommendations for the use of modern lamp types.
