I have a UV source like that. Only problem is it kills any bugs that fly near it and I took that as an indication probably not safe.
I need one of those for my carport. I could turn it on in the morning and turn if off before I go outside. But still, I'd put it behind a Fresnel lens:

Then add barn door shutters to focus it at one spot.
