The Hinkley Lighting 1558BK Landscape Path Light Landscape Black is a 21.5 high path light using a 12 watts wedge base bulb to cast a down-light along pathways and walkways. The lampshade is 6 wide and is shaped and designed to resemble an oyster shell and the fixture has a black finish on a die cast aluminum construction. A unique feature of the 1558BK Landscape Path Light is that the height of the light fixture is adjustable from 15.5 to 21.5, depending on the design requirement. The 1558BK Landscape Path Light functions on 12 volts and needs to be connected to a low voltage transformer for its operation. The transformer has to be bought separately, since multiple low voltage lights are usually connected to a single transformer. The standard accessories included with the 1558BK Landscape Path Light are a heavy duty ground spike made of durable composite material and a wiring kit, apart from the bulb.
