Light Light is a floating light. When turned on the balloon heats up and floats into the air. When turned off, the balloon cools and gradually sinks to the floor. The light‘s charm and character create a relationship with the user. The balloon works by being only fractionally below equalibrium when turned off due to helium inside the sealed baloon. The high heat produced by the halogen bulb brings the temperature of the helium up and causes the balloon to rise.
