I've had a germicidal lamp more or less in storage for a number of years,
but recently brought it out to sterilize a room where a person had been
sick. However, I don't know if it still emits the germ killing UVC
spectrum. What's a quick way I could tell for sure? Thanks.

My mom had a dryer with UV lamp, think it was for the ozone fresh smell. I
noticed in the hospital they had random UV lights facing up in hallways. I
would think some device using filter to determine band exists. I recall
hearing of a UV device wheeled into rooms for sterilization.
