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.

A light-guiding component includes a light introduction section, the light introduction section including a first light incidence portion and a second light incidence portion that face different directions. The first light incidence portion is capable of receiving incident light from a light source that corresponds to the first light incidence portion, and the second light incidence portion is capable of receiving incident light from a light source that corresponds to the second light incidence portion. A light-guiding section provided with a light exit surface and configured to guide the light from the first light incidence portion or the second light incidence portion to be propagated therein and then exit from the light exit surface.

An optic configuration including a PCBA with one or more LEDs mounted thereon to emit light through a lens and a reflector. The optic configuration may be assembled within a cavity of a lighting fixture. At least a portion of the emitted light may be subtended by the lens, such that the lens may subtend light through a number of regions (e.g., three distinct regions). At least a portion of the emitted light may be subtended by the reflector, such that the reflector may subtend light from a number of surfaces (e.g., four surfaces). At least a portion of the light subtended by the lens may further be subtended by the reflector. The light subtended by the lens and/or the reflector may form a beam pattern including a high intensity spot portion and a lower intensity flood portion.
