A flight obstacle light fitting having a tubular body (1) provided with light emitting semiconductor light sources (3), such as LEDs or emitters, fitted around it on its outer circumference at at least one level and provided with directional lenses, oriented horizontally outwards. The tubular body (1) is completely open at both ends to allow more efficient cooling, and the tubular body (1) has a polygonal outer surface, providing an even mounting surface for the light sources, especially to permit more efficient transfer of heat to the body. |
