When electric power is converted from AC to DC, there are losses and changes to the electrical properties; these effects are known as the “Power Factor”. In an LED lighting installation it is necessary to use the VA value of a fixture in order to compute and select a transformer with adequate power for the system. For your convenience Kichler supplies the VA as well as the Wattage for each of the fixtures in our catalog. What does this mean to the system designer? There are two areas to consider: the load on the transformer and Watts consumed according to the electric power company. The load on the transformer The “VA” (volts x amps) rating on Kichler Landscape products represents the value used when calculating the total system load. This VA number will help you determine the correct size transformer for an LED installation. Example: Number x VA value of Fixtures LED Energy & Cost Comparison ENERGY USE Average Installed System 340W 6 hrs/Day 340W DESIGN PRO LED ACCENT 340W 340W WATTS CONSUMED LED fixtures consume approximately 75% less electricity than an incandescent of similar lumens.
