The colour under UV immediately brought to mind the space LEGO sets I enjoyed as a kid in the early 90s: https://lego.fandom.com/wiki/6923_Particle_Ionizer

I wonder if uranium glass was actually the inspiration for the neon green elements in these pieces?

Yes! I thought the exact same thing. I used to love that color.

Thanks for resurfacing my childhood disappointment; I had one of those sets, but no black light.

> space LEGO sets I enjoyed as a kid

As a kid? Now as an adult with disposable income, I can get really awesome LEGO sets, sets I really enjoy building. I prefer Technics, but also have several star wars sets, including the model death star (not the one with the minifigs) and the original 32" star deatroyer. Post Christmas this year was spent building a lot of LEGO City sets.

I also have the Saturn V and ISS sets, both of which are awesome.

Sharp catch! I also played with "space" Lego from around that time (including with that colour). I always found it more greenish yellow rather than yellowish green. I guess because I liked to combine it with yellow, rather than green. YMMV, obviously, but I do find the colour rather different than the one in this article.
