“But LEDs make it simpler: They don’t give off UV at all.”
Considering that there are ultraviolet LEDs out there, that article was drastically oversimplified.
Properly-built LEDs (as long as they aren’t specifically designed for UV light, of course) won’t give off a lot of UV, but they can give off some. Consumer LED bulbs will convert generated UV to visible light with phosphors, which is probably what the article is talking about. It depends on how the light source is built - if you’re dealing with bare LEDs with a diffuser, YMMV.
It’s tough to tell from your image how the light is put together, and it may not matter much depending on how you’re using it and any other UV sources in the area.
