Flag High Mast

A flag that is at half mast has been brought down to a point halfway down the pole as an expression of sadness at someone's death: The flags at Buckingham Palace were all flying at half-mast.High-mast lighting is a tall pole with lighting attached to the top pointing towards the ground, usually but not always used to light a highway or recreational field. It is used at sites that require lighting over a large area. The pole that the lighting is mounted on is generally at least 30 m (98 ft) tall (under this height it is referred to as conventional lighting system),[1] while the lighting consists of a luminaire ring surrounding the pole with one or several independent lighting fixtures mounted around it. Most units have four, six or eight lights in the ring, with three, five, ten, twelve and sixteen lights used in rarer instances.
