That's not very sensible.

It is UV, because it would glow up some of my floride rock samples.
That doesn't mean it's UV, some things fluoresce in blue light. That's how white LEDs work, they use a blue LED with a broad emitting yellow phosphor on top of it to produce white.

We talked electronics so far, lets talk physics now

To have a stable drip rate you need a constant pressure in the vessel where the drops come out.
Remember the experiment with a vessel and three (vertical) holes in it. Liquid sprayed farest from the lower hole because the pressure was biggest there.
I don't know what you're using now but I suggest some bowl way larger than high so that the pressure remain constant resulting in a constant drip rate.

Focus on a stable drip rate instead of complex math

I guess your right, but It came with a UV warning label with a big yellow triangle and a ! mark, and also about the cancer risks of UV radiation and the state of california and stuff. I guess that would make it UV! I was bored and wanted to look at it, I guess.
