They used the wrong type of bulb. Ordinarily the bulb will be made of a UV blocking glass, and not be quartz based. I think? So it’s not usually the shroud that stops UV except in cases of Halogen bulbs. These would be CFL without any shield except perhaps a cage to protect against things thrown.

The bulbs in this picture sure do look like UC-V sterilizing lights.
