A balloon light is usually filled with:

Explanation:
Balloon lights rely on a gas inside the envelope that is lighter than surrounding air to provide lift and support the light. Filling with helium gives real buoyancy so the balloon floats, while filling with ordinary air is used in setups where buoyancy isn’t required. Water would add too much weight and cause the balloon to sink, and nitrogen or oxygen don’t provide lift for this purpose. So the usual filling is air or helium.
