The Hinkley Lighting 1520BZ Low Voltage Spot Bronze is used by customers to focus visitorsÂ attention on outstanding features of their landscape design, such as exotic shrubs, water bodies, interesting rock formations, or even a tree which can cast a dramatic silhouette. The 1520BZ Low Voltage Spot Bronze is made in a bronze finish and uses a 50 watt bi-pin bulb drawing low voltage current. The lampshade is 5.5Â wide and can be tilted upwards and downwards for better focus. The main requirement for any outdoor or landscape light fixture, including spot lights, is their ability to withstand the constant attack from the elements as well as cope with dampness and moisture on the ground and in the environment. For this, only light fixtures with higher IP rating are preferred for outdoor lighting. The IP rating is an international norm which determines the effectiveness of the insulation of any electrical power consuming appliance.
