You are correct. However for my use reducing the brightness had the desired affect. If Alton can do the same it will at least make the effect passable.It's likely a lot brighter in real life than these photos. Camera's don't see so well in the dark. Unless those people are doing a mannequin challenge for the long exposure lol.
The problem with those LED's is not brightness, it's the wavelength. A proper black light tube will emit UV at around 350nm - 365nm wavelength - which is zero visibile light. That's what makes things glow and any surface painted black will simply be invisible.
LED's can't go down this low in wavelength, at least without considerable high cost. The standard LED UV units on the market generally emit at a wavelength of around 400nm to 420nm, which does include visible light - a very deep shade of blue, and that will ruin any optical illusion which relies on UV effects.
This is why everything in the photos is so brightly lit. They are using LED's.
I think the problem with these LED UV's is that they are mostly designed for nightclubs. In a club the blue glow isn't an issue, if anything it adds to the atmosphere. On the flipside black light sets in theatres and theme parks seems to be a dying effect. Screens and projector effects (such as 3D screens and projection mapping) are becoming more common place.
