Abstract
The invention relates to an airfield light comprising a body, a medium intensity lighting arrangement, and a high intensity lighting arrangement. The medium intensity lighting arrangement provides an omnidirectional light source, and the high intensity lighting arrangement provides a unidirectional or bidirectional light source. The invention is energy efficient compared to conventional airfield lights, and has particular application to temporary airfields. LEDs may be used as the light sources.
