The Hinkley Lighting 1530BZ Low Voltage Spot Bronze is a 2.5 high low voltage spot light made in a bronze finish enclosure which holds a 3.25 wide lampshade capable of hosting a 20 watts bi-pin bulb. Since the 1530BZ Low Voltage Spot works on 12 volts current, the voltage of the domestic line current has to be stepped down using a low voltage transformer. Generally, outdoor lights use low voltage since it is conducive to the use of energy-efficient LED bulbs. The most generic use of the 1530BZ Low Voltage Spot is for accent lighting of trees, shrubs, water bodies, statuary and landscape designs which are outdoors. This means that the 1530BZ Low Voltage Spot has to be rugged with sufficient insulation properties to withstand the impact of elements as well as seepage of water. The resistance of spot lights to solid and liquid particles is designated with their IP rating, which is a 2 digit rating protocol with the first digit signifying protection against solids and the second, against liquids.
