Conversion kit for medium-pressure (MP) ultraviolet lamps in Berson disinfection systems, 100 mm size. Berson's InLine range is a medium-pressure series, and a conversion kit supplies the parts needed to adapt a lamp position to the specified size rather than replacing the lamp assembly outright. The 100 mm figure is the size designation carried by this kit and distinguishes it from the 50 mm variant; match it against the installation before ordering. Reference number 10267-0117, 100mm.
