Hello:
Regarding to the mentioning of the automotive HID lamps as one of the application of xenon arc lamp: This is false.
I've several sources and I also know generally, that the real technology that are used in automotive HID lamps, isn't a xenon arc lamp like in the case of cinema and IMAX projectors, but a metal halide lamp, as the light comes mainly from mercury sodium and scandium halides, with the xenon being only used as a starter gas to provide the initial light during lamp ignition.
Source: 1, 2, 3, 4. Other source and yet other source.
Also, in the articles xenon arc lamp and metal halide lamp are written that the "Xenon headlamps" are actually metal halide lamps and genreally what I'm trying to explain and users refuses to get and hence undone my changes non-stop, and the reason why it is needed to remove or at least modify the mentioning of the automotive HID lamps in this article. זור987 (talk) 13:01, 4 September 2016 (UTC)
Xenon dichloride, tetrachloride, and tetrabromide have been reported from the exotic radiochemical route of beta decay of the analogous iodine-129 interhalogen anions, according to Greenwood and Earnshaw. (The decay energy of iodine-129 is but a paltry 0.194 MeV, which is so low that even the fantastically weak Xe–Cl and Xe–Br bonds that result are not broken.)
