[edit]I made a small clarification link to make sure that everyone knows that Bramah company was Joseph Bramah and not anything to do with Ernest Bramah Smith, Pernambuco 14:00, 11 December 2006 (UTC)

Ruhmkorff Lamp fluorescence
[edit]The statement that a red Ruhmkorff lamp excited green fluorescence from a uranium salt is dubious. Except in special cases, fluorescence can only be excited in a lower colour, i.e a longer wavelength, a lower energy than the exciting radiation. Exciting a higher energy state requires high-intensity radiation, which it is doubtful the Ruhmkorff lamp produced. The reference cited is quite explicit, but I wonder if it is accurate? Perhaps the white CO2 Geissler was used? --D Anthony Patriarche (talk) 02:16, 7 July 2018 (UTC)
