Interesting project. The good news is that the answer you want is no:
making the bulb-wire connection safe (...) for others to be around/touch (interested kids, pets, etc) is NOT beyond the reach of an amateur.
I said "an amateur". If you'll be the amateur who can do this is another thing. :-)
Their site says that they use an exclusive lamp: "With special halogen bulb 35 W, produced exclusively for IngoMaurer GmbH, only for use in the Lucellino product family. Luminous flux: 600 lm, light efficiency: 17 lm/W, output: 35 kW/1000 Std. 2000 h, CRI 100, EEC C. Socket E27. The bulbs are mentioned as exception in the EU regulation 244/2009."
I would try another kind of approach, and would not use AC. Obviously it wouldn't be just like the professional item, but would be more feasible. And more safe, although the risk of broken glass is the same as the original thing.
Now, the part of the answer that IS NOT about electrical engineering.
- Use old glass lamps; hollow the bulb as shown here
- Apply mate varnish to the bulb. There is craftmanship varnishes that can be applied to glass.
- Use bare 18 AWG copper wire; normal wire stripped of the cap; apply a coloured varnish to the wire.
- Inside the lamp, use a cluster of warm-light leds, rolled with tissue paper. The led circuit can be lighted with single cells. The leds could be these.
- The AWG 18 wire would hold the lamp; at the bottom of the lamp, the leds' wire would be connected to the external wire. After the connection, you would use epoxi glues to hold everything.
- you still need to provide the wings.
