This slide shows two street light applications. The application on the left has four LEDs per LED cluster, twenty-four units per canopy. Each string requires 15V at 350mA. The twenty-four strings require 15V at 8.4A. For this application 136W is required, and a 150W supply is chosen. While the LED enclosure is rated to IP66, the Advanced Energy supply meets IP67. The application on the right is similar, except there are thirty-six units per canopy. This requires 15V at 12.6A for a total power of 180W, so a 200W supply is chosen.
