No pictures of the bolt-together cages, sorry.
Regarding UV lights to control pathogens, these are not the type of lights you would put in a cage, if that's what you're asking. They are very dangerous lights that produce large amounts of radiation in the UVC or germicidal range.
The do make germicidal filters that keep the lights entirely enclosed and air is drawn in over the lamps, therby killing a large percentage of airborne pathogens.
Here are some good key words and acronyms to try in google.
UVC
germicidal
UVGI
ultraviolet germicidal irradiation
