Hi all,
Electronics noob here. I want to put together a simple circuit that (at the moment) consists of a power LED (one like this ideally), a potentiometer and a 9V battery.
The application is for a play - ideally we'd have the LED on an actor's chest, with a wire running to the battery and potentiometer, which are in his/her pocket (so they can vary the brightness of the light from their pocket).
The theater can be kept fairly dark, but I'd like the LED to be bright enough make it very clear to the audience that the brightness is changing, as well as illuminate the actor's face a little if possible.
Unfortunately, I'm no Michael Faraday... so I'm a bit confused as to how it should all work. I have brought with me a list of questions for you fine folk.
I'm based in Ireland, so I'll probably order from Radionics.

- Would a circuit with a power LED, potentiometer and 9V battery work sufficiently for my purposes, or do you see me needing more robustness?
- What power LED intensity would you guys recommend?
- Would the LED be uncomfortably hot if e.g. I taped it to my TShirt?
- Do you know of any methods to protect the soldering joins from the wires to the parts? I'm conscious of any bit of tugging possibly pulling a wire off.
- How quickly (roughly) would the 9V battery drain?
