Abstract: A lighting system (1) includes six equally circumferentially spaced apart and radially diverging light modules (3, 4, 5, 6, 7 and 8) for emitting light. The modules are disposed closely adjacent to each other and the light collectively defines a beam of light that is directed along a primary axis (9) in a first axial direction (10). A plurality of heat conductors, in the form of six like sets (13, 14, 15, 16, 17 and 18) of heatpipes, allow heat to be drawn away from respective modules (3, 4, 5, 6, 7 and 8). Each set of heatpipes includes eight separate continuous heatpipes, and each heatpipe in each set includes a first end (19) that is thermally connected to the relevant module and a second end (20) that is radially spaced apart from the first end (19).
