Abstract
A lighting device comprises a plurality of light emission devices (4, 5) housed in a common casing (1). Each of the light emission devices has a reflector (2, 3) each of which are adjustable independently to direct light in different directions. Although the invention is not restricted to any particular field it finds special application to the provision of a flash gun for flash photography and is particularly suitable for electronic flash guns. <IMAGE>
