Otherwise like you said there are alredy diving lights with UV or blue light features, including some cheap clones on Wish or Aliexpress. I will try to list the options here

Just one mention - about wave length...
There is not a one UW light... Blacklight - Wikipedia
at least you have 400-380nm light (more used in Wood`s lights) - with bright violet light striking
You can stop it by UV black filter to get "True black light"... but
There is another 356 nm light. you can use this lamps... it should be much better.
Which is better: a 365 NM flashlight or a 395 one? - Quora

Not really relevant. The point underwater is NOT to have a UV light, but to excite the fluorescence ....which works better in the violet, which is why the yellow filter is needed on the receiving end to block the blue so all you see is the fluorescence.
NIGHTSEA - Practical Solutions for Fluorescence is the premier website, and Fluorescence Appearance can Depend on Excitation Wavelength - NIGHTSEA has the information you need.
This is actually off topic but searching about the fluorescent species of the mediterranean I found out that there is a bioluminescent one which is very common the jellyfish Pelagia Noctiluca
Saw it many times in the daylight, I didn't know it's bioluminescent. Indeed "noctiluca" in Latin means "that emits light in the night"

I believe I found on Aliexpress a light with blue color that might be used for this purpose together with a yellow filter let's say the Backscater for example

The price is good around 30 USD per light and blue is just one of the possible color options so the lights can be used "normally" and then switch to blue when necessary. I don't expect them to be as good as the best products quoted in the discussion above, but if they are just good enough they might be worth a try
