Deck lighting has really come along in the past number of years, particularly with the growth of LED lights. These little gems require almost no power and because they are low voltage there are zero risks.
Put them in your wood decking, among the plants or even in the side of your condo to highlight a step up into your condo. All look great and give you just enough light to see without disturbing your great view.
I've put a few here from Highpoint Deck Lighting, a family firm in Colorado because they have a real nice collection which can be adapted to any condo balcony or terrace.
