QuiQue,

I would think that some of the light-emitting diode (LED) lighting that is available would do about what you want. Super low current drain so it can be wired with hair-thin leads, yet it puts out a decent amount of lumens. They're available in pretty good colors these days, not just the old red and blue of the past. Some of them go up to five watts and put out enough light to equal a good-sized spotlight. I'd check with an electronics parts supply house to see what is available.

For the crystals, I'm mostly stumped, unless you can find something at one of the big craft stores or Pier-1 type places. I mean, crystals are so last-year, y'know? (grin)
