An excimer bulb assembly including an excimer bulb and a pass filter such that the excimer bulb assembly does not emit substantial UV radiation in wavelengths longer than 231 nm, 232 nm, 233 nm, 234 nm or 235 nm. The wavelengths are measured at an incident angle of zero (0) degrees to the filter plane. The pass filter is preferably constructed of a plurality of layers of hafnium oxide, and most preferably constructed of less than seventy five (75) layers of hafnium oxide. The excimer bulb, pass filter, and two electrical connectors may be adapted to form a cartridge which may be adapted to swivel along its main axis. The cartridge may further include a smart chip. The smart chip may retain and store information regarding the assembly and preferably retains hours of use of the excimer bulb.

In the excimer lamp according to the present invention, a flat discharge vessel having a substantially rectangular cross-sectional shape and comprising a pair of planar parts and a pair of side-surface parts has a pair of external electrodes disposed on the respective outer surfaces of the planar parts. The end parts of the external electrodes are provided with an auxiliary electrode extending to a region that is made smaller than the distance between the planar parts. A lead that supplies electricity to the external electrode is connected to the auxiliary electrode in the region that is made smaller than the distance between the planar parts.

A Far UV C excimer bulb assembly including an excimer bulb, and at least two filters. The excimer bulb emits a path of light in at least two wavelengths. The at least two filters remove all wavelengths of light that are hazardous to human tissue. The at least two filters may each be placed perpendicular to the path of the light generated by the excimer bulb. The at least two filters may be a single, curved or cylindrical filter. The assembly may further include a mirror which may also be curved.
