A flame detector including an ultraviolet emitter configured to emit ultraviolet light at a strike voltage less than or equal to approximately 230 volts. A method of manufacturing an ultraviolet emitter for use in a flame detector, the ultraviolet emitter including a hermetically sealed, alkali rich, ultraviolet transmissive glass envelope, the method including: (a) wrapping an envelope exterior surface with a conductive material; (b) performing a first injection of at least one non-radioactive gas into the glass envelope at a first pressure; (c) applying a voltage bias to the glass envelope; (d) baking the hermetically sealed, alkali rich, ultraviolet transmissive glass envelope at a baking temperature for a baking duration of time; (e) cooling the hermetically sealed, alkali rich, ultraviolet transmissive glass envelope to a desired temperature; and (f) performing a second injection of at least one non-radioactive gas into the glass envelope at a second pressure.
