[0041] A distance between a center of gravity 46a of the base housing 16a together with the lighting unit 12a, the battery interface 18a and the removable battery 20a arranged thereon and the pivot axis 28a, measured parallel to the installation plane 34a, is greater in the stowed position than in the operating position. The base housing 16a, the lighting unit 12a, the battery interface 18a and the removable battery 20a form the basic light unit, which can be pivoted relative to the handle unit 24a via the joint unit 26a. A distance between a center of gravity 46a of the basic light unit and the pivot axis 28a, measured parallel to the installation plane 34a, is greater in the stowed position than in the operating position. The basic light unit is therefore pivoted in an erected state when moved from the stowed position to the operating position via the pivot axis 28a.The center of gravity 46a of the base housing 16a, together with the lighting unit 12a, the battery interface 18a, and the removable battery 20a arranged thereon, is arranged in the stowed position between the installation plane 34a and a plane intersecting the pivot axis 28a and oriented parallel to the installation plane 34a. The center of gravity 46a of the base lamp unit is therefore arranged in the stowed position between the installation plane 34a and a plane intersecting the pivot axis 28a and oriented parallel to the installation plane 34a. During transport by the handle unit 24a, in particular by the handle base body 30a, the center of gravity 46a of the base lamp unit is arranged in the stowed position between the installation plane 34a and the pivot axis 28a. This prevents rotation or unfolding of the base lamp unit when held by the handle base body 30a.
