eBay UV flashlights/lightbulbs and their safety

Hello!
I made an account just to ask about thise here, I will surely make further contributions but I hope you guys don’t mind helping me out.
Basically, I am a huge UV light addict. I have purchased several in the last month and it is all too fun to see how things fluores under them. They’re not all LED but I hope that’s not an issue on this forum. I use the UV for photography of flowers and other objects, there’s two kinds of pictures I do, one is the actual reflected UV and the other is a picture of the fluorescence that is caused by UV. Here’s how it works with a common daisy:

I hope you didn’t mind the little tangent, now to get to the point. I love UV lights, I want to get more of them, I looked up a lot of them on eBay and I have plenty budget items in my sights to potentially order. However my question is, how safe are they? I don’t want to end up getting an electrical shock or having the thing catch on fire. bigclivedotcom has especially made me vary of this since he tore down a lot of eBay products and proceeded to mock them for their rather unsafe construction. I would not leave those things on unattended but I would still hate to get electrocuted. I don’t exactly position those things in such a way that I would get stuck on them if they were to shock me but I still want to be safe.
Here are the things I would like to buy, they’re not all LED but I hope that’s not an issue.
365nm lightbulb This one is especially attractive, very cheap and I would try and mod it so that I could mount a filter on it to purify the UV. Afaik 365nm unbranded LEDs put out a lot of visible light too.
fluorescent bulb 1
weird filtered flashlight? With this one especially, I wonder what the filter is, I suspect it is made by Tangsinuo and I wonder how much it cuts down the amount of UV emitted, anyone own this one?
arguably fancier LED bulb
ridiculously powerful bulb
fluorescent bulb 2
How sketchy do those seem? Should I buy them or avoid and save up for something less shady?
Thank you!

Doubt you’ll get shocked by any of them (but if you get the new Wuben Steel Cannon, it must and will be shocking to you!), but the worst you’d have to worry about is mislabeling. They might claim 365nm, but might actually be only 405nm violet, or worse, 470nm blue.

Eg, I doubt a “DJ atmosphere bulb” would be 365nm, unless you want to fry everyone’s retinas… and then get sued.

1. The Wuben Steel Cannon? What is that?
2. That’s the thing, the one flashlight I have bought is indeed 365nm and works perfectly fine. It’s when you try and buy products that claim to be UVC when you start running into scams (such as getting LEDs that are actually 395nm or such). I suspect those 365nm LEDs are all made in the same factory for really cheap and all the other manufacturers just buy them in bulk.
3. They’re probably calling it DJ atmosphere bulb since they just need some name for it. People use those LEDs for various specific reasons and the people in charge of the accounts are often not the most well educated on what they’re used for.
Or am I giving it too much benefit of the doubt? I don’t know, what I do know is that apparently 365nm LEDs can be had for dirt cheap since the aforementioned flashlight I have is in fact 365nm and cost like 4 USD with free shipping. And the crazy thing is that it’s full metal construction with a focusing mechanism and a weather sealing gasket on the battery lid. The body is actually just a repurposed Alonefire SK68 that someone put the UV LED instead of a white one.
