Commission Delegated Directive (EU) 2019/177 of 16 November 2018 amending, for the purposes of adapting to scientific and technical progress, Annex III to Directive 2011/65/EU of the European Parliament and of the Council as regards an exemption for lead as activator in the fluorescent powder of discharge lamps containing phosphors (Text with EEA relevance.) · European Union

(6) Lead activator in the fluorescent powder is required to allow the barium silicate phosphor to fluoresce. It transforms the 254 nm radiation to the designed UV (290 nm-400 nm) radiation and it is used in over 95 % of the indoor low pressure mercury vapour fluorescent lamps in tanning and certain medical applications. It provides UV intensity at the wavelength of 350 nm that is crucial in order to initiate skin pigmentation.
