A variable hanging lighting, which is mountable on a carrier to form a designed lighting fixture having a three-dimensional shape, includes a flexible light strip, a flexible long channel member and multiple slings. The light strip has multiple luminous bodies arranged in a linear array to form a luminous surface on the light strip that outwardly emits light. The long channel member includes a bottom with multiple locating holes, two side walls, and two convexly fixed flanges that form a notch that accommodates the light strip. The slings each have at least one engaging element connected to a respective locating hole via an engaging connector to hang the long on a carrier so that the bottom of the long channel member is close to the carrier, and the luminous surface emits light in a direction away from the carrier.
