1. A sanitizing system comprising:
multiple ultraviolet (UV) lamps each including one or more UV emitters configured to emit UV light, wherein the UV lamps are positioned to emit the UV light towards target components within a space, so that a first UV lamp of the UV lamps is positioned to emit UV light towards a first target component within the space and a second UV lamp of the UV lamps is positioned to emit UV light towards a second target component within the space; and
a power supply module electrically connected to each of the UV lamps and configured to provide electrical energy to the UV lamps to power the UV emitters to sanitize the target components,
wherein the UV lamps are connected to the power supply module via different respective electrically conductive leads that each extend from a housing of the power supply module to an enclosure of a different corresponding UV lamp, wherein at least some of the electrically conductive leads have different lead lengths relative to one another to vary output levels of the UV light emitted by the UV lamps, wherein the different lead lengths are selected based on different distances between the UV lamps and the target components so that a first electrically conductive lead connected to the first UV lamp is longer than a second electrically conductive lead connected to the second UV lamp based on a first distance from the first UV lamp to the first target component being greater than a second distance from the second UV lamp to the second target component.
