A balloon-carried light effect is a special effect carried by a balloon, which can be fixed with a rope to the ground or free-flying. ==Uses== Balloon-carried light effects can be used without safety concerns at events with a lot of people, because they do not require the use of flammable substances and there is no danger of falling debris as there is with fireworks. Nevertheless, the brightness is much lower, when non-dangerous light sources, such as lightsticks or battery-powered lamps are used. Balloon-carried light effects cannot replace fireworks, but supplement them, because of their long lighting time (if lightsticks or battery powered lamps are used) and because of their inherent safety. To realise a balloon-carried light effect, one or more balloons are used, capable of carrying a lightstick or a small battery powered lamp. Further it is possible to insert one or two small lightsticks into a transparent balloon. It is also possible for larger balloon-carried light effects to use tethered balloons, which also can contain an electric cable power supply: these 'artificial moons' may be used for floodlighting. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Balloon-carried light effect」の詳細全文を読む スポンサード リンク
