Not 100% true jingles, you can dim fluorescents with a Sine Wave dimmer, which are very expensive.
All light sources emit UV. Nothing has the same effect as fluorescents because fluorescents output a lot of UV do to design. So much so that they are used to sterilize things. All fluorescents have a coating to block UV so it doesn't hurt anyone. Black light fluorescents don't have as strong a coating, allowing save levels of UV out. They are also colored purple because UV has no color technically. The purple color is a safety feature to know when they are on or off.
LEDs also put out UV, just not nearly as much. 'White' LEDs are actually UV LEDs with a coating to block UV so they look 'white' if I remember correctly.
You can also try UV filters on dimable lights. Companies like Apollo and Rosco make glass filters that block a lot of visible light and only let UV through. They still aren't as effective as fluorescents, because they are designed for visible light, not UV. UV is just a by product. They also still let some visible light through, so you get a glow. Very dark blue and purple gels can also give a UV effect, but again, they still have a glow.
