Mad scientist,, that's a first. Radio triggers? No. I'm a little more low budget.
My arsenal consists of a small LED flashlight, hand held spotlight, My old flash from my Cannon AE-1, and different colored pieces of plastic sheet.
I use long exposures and walk around lighting up what I think will look good. I cover the flash with the plastic sheet and use the test button to light up a bigger area. The spot light is used mostly to help me focus. Sometimes if the subject is inaccessible, I cover the spotlight with colored plastic and paint away. I have to be quick since it gets hot and easily over exposes.
The Moon is the best light source.
