UV lights like those can be used in upper room systems where they are aimed horizontally well above occupants. They rely on airflow to move particles into their kill zone. The effectiveness of such systems is still a matter of study (and they are expensive) so they are not widely used. Certainly, a technology that could be used to flood an entire room with light would be far more effective and could gain widespread use. sje

Bulbs like this are routinely used inside of class II biological safety cabinets. In the U.S., I was accustomed to working in "hoods" that had a toggle switch, giving you either fluorescent or UV, but not both. Went to Germany for a postdoc, and the hood that I inherited had one control for each. And when the fluorescent light was on, it was difficult to tell that the UV was also on. There's a glass barrier that you look through to work, but light (not bugs!) escapes under it. My eyes were fused closed for a couple of days, with inflammatory gunk acting like glue. Felt like sandpaper for eyelids. Snow blind.
