Based on mortality curves and experience, WIL-CAL can determine and minimize nuisance trouble calls by systematically employing timely Group Relamping strategies. Coupled with this information, WIL-CAL can also recommend the alternatives between Group Relamping or Retrofitting. With all new lighting equipment, the necessity for maintenance will be virtually eliminated for at least three years (varies with operating hours). Retrofitting provides significant energy savings and state of the art lighting technology that provides enhanced illumination. Always familiar with on-going Utility Rebate Programs, WIL-CAL can assist with proper form usage and applications that has helped streamline and accelerate the project payback period. This increases the return on your investment.
