5 :, Abstract, IMPROVED SPOTLIGHT ARRANGEMENT A spotlight comprises a light source (14) mounted within an enclosure (11) fitted with a light-transmissive cover (28) which is formed with a central opening (29) above the light source. A clearance space between the light source and the cover allows light from light source (14) to spill over into the enclosure and thereby illuminate the cover from behind. Another enclosure (12) containing control gear (17) for the light source is thermally insulated from enclosure (11) by an air gap (21).
