They aren't halogen bulbs, just ordinary low wattage filament bulbs.
I don't remember the wattage off hand, but I can check if you are
interested.
You don't say how big is big, but voltage drop using AC shouldn't be
a significant consideration over a few hundred feet. Some of the
transformers are suitable for outside use, so you could always run
240V to the transformer site and then distribute LV.
Sorry, I've never come across LED based outside lights - and I
suspect that even with the improved efficiency, there won't be a
significant power saving for illumination purposes. Plus you will
either need a local regulator for each lamp, or you have to
distribute DC with the associated power loss problems.
