1. An excimer bulb assembly, comprising:
a krypton/chloride excimer bulb and a cutoff filter;
said krypton/chloride excimer bulb adapted to emit light at wavelengths in the UV C spectrum;
said cutoff filter including a plane;
when light emitted from said krypton/chloride excimer bulb at an incident angle of 0 degrees to said plane, said cutoff filter is adapted to substantially block wavelengths longer than 234 nm;
said cutoff filter allows transmission beyond 237 nm.
