Putting lamps in ducts is not very different from putting filters in ducts; but with the downside that I’m a lot more worried about fraudulent lamps than filters. I guess it’s easy to retrofit a lamp into a duct, whereas a filter slows the air; but you probably already have a system designed with a filter.
The point of lamps is to use them in an open room where they cover the whole volume continuously.

And I guess having the UVC in ducts doesn’t disinfect surfaces in rooms, so you’d need a separate solution for that.
