A current limiting device includes a substrate or carrier body at least partially formed of electrically insulating material. One-way valves may be positioned at seal locations in association with passageways to allow venting of overpressure within the interior volume of the flashlight. A method for converting from a data format based on hierarchies to XML includes: translating at least one record including information stored in the file format based on hierarchies to an intermediate format; and, applying a stylesheet to the at least one record in the intermediate format thereby generating at least one XML file being indicative of the information and suitable for transmission. The time gradient of the current is preferably chosen such here that minimum values for the luminous flux of the lamp are achieved at given moments.
