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.

The present invention provides a bulb (100, 110, 120, 130, 140, 140′) an excitation chamber (200, 210, 220, 230, 230′) a ferrite core (300, 310, 310′), a spool (400, 410); an assembly or subassembly of such components, and a lamp (100, 1100, 1200, 1300, 1400, 1500, 1600, 1600′, 1600″, 1700, 1800) for producing electromagnetic radiation, such as in the light spectrum, UV or IR.
