An electrical power distribution arrangement for a lighting system comprises a power track (1) having a non-conductive track body (2) carrying a pair of conductor rails (8, 9) in respective grooves (5, 6). A lampholder (20) is slidably and rotatably received on the track and has a conductive body which is divided radially into two halves (20A, 20B) to form a pair of pick-up contacts encircling the track. An insulating spacer (30) is received on the track on each side of the lampholder and each spacer carries a distribution contact (32) which is received in the groove of a respective conductor rail and is resiliently compressed between the respective conductor rail and the respective lampholder half so as to supply power to the lampholder regardless of the angular orientation of the lampholder. |
