The Hinkley Lighting 1573BK Landscape Path Light Landscape Black is a 21.5 high low voltage path light in die cast aluminum construction in black finish with a 8 wide umbrella shaped lampshade casting down-light from a 12 watts T5 wedge base bulb. The height of the 1573BK Landscape Path Light is adjustable from 15.5 to 21.5, depending on the design requirements. This means the 1573BK Landscape Path Light can be used for lighting walkways, pathways, garden fences and even for step lighting. Since the 1573BK Landscape Path Light uses low voltage, it has to be connected to a low voltage transformer to convert the normal domestic line voltage to 12 volts. Normally, a group of low voltage lights is connected to a single transformer, which is selected based on its ability to cater to the combined wattage of the lights. The 1573BK Landscape Path Light is accompanied by the bulb, standard wiring kit and a heavy duty ground spike of durable and corrosion resistant composite material, while the transformer is to be purchased separately.
