An elongated, indirect lighting module comprising a plurality of LEDs arranged along a longitudinal axis in a housing provided with a mounting element having an elongated shape in axial direction. The elongated lighting module further comprising suspension elements for suspended connection of the housing to a ceiling. Each suspension element has at a first end a first connector connected to the mounting element, and at a second, opposite end a second connector for connection to the ceiling. The suspension element via its first connector is displaceable along the longitudinal axis over the mounting element, and the LEDs are configured to issue light into a radial direction essentially away from both the mounting element and the suspension element and for a major part toward the ceiling.
