Shown here is a retrofit example of how the XP Gen 2 provides multiple design possibilities for existing XP Designs. In this example, the designer replaced 7 XP-Gs with 7 XP-G2s and the result is over 30% better lumen output and over 30% light output using the same number of LEDs at a comparable cost. The designer also looked at a lower cost solution with comparable performance to the original with the XP-E2 LED. In this example, 7 XP-Gs were replaced with 7 XP-E2s and, as one can see from the table, the designer was able to get similar if not better performance than the original design, again at a significantly lower cost.
