Abstract: A lamp for use in a lighting strip system which includes a support rail, which extends along a longitudinal axis, and supply lines for supplying power to a light source of the lamp. The lamp has a first unit for arrangement on the support rail and for electrical contact to the supply lines, wherein the first unit includes an operating device for supplying power to the light source of the lamp. The lamp also has a second unit which includes the light source, and a plug connection device, having a first and second plug connection element, via which the second unit can be electrically connected to the first unit. The design having two units which are connected to each other enables the entire weight of the lamp to be divided across the two units. The two units can thus each be more easily handled, for assembly on the support rail.
