      What are the use-case and failure-specific criteria used for RMA evaluation?

      Discover the key questions to clarify a fixture's use case and understand its failure, providing US LED's Engineering Team with the necessary context for a thorough evaluation.

      During the RMA process, the US LED Engineering Team carefully evaluates fixtures using the following criteria to ensure a thorough and accurate inspection:

      Use Case and Installation Details

      Installation Environment:

      • Where is the fixture installed (e.g., warehouse, retail space, office, outdoor setting)?
      • Is the fixture exposed to any environmental factors such as high humidity, extreme temperatures, or direct sunlight?
      Mounting and Positioning:
      • How is the fixture mounted (e.g., ceiling, wall, suspended)?
      • Is the fixture installed in a location with proper ventilation or airflow?
      Control Systems:
      • Are dimmers or control systems (e.g., DALI, 0-10V, DMX) used with the fixture?
      Operational Conditions:
      • What is the average operating time per day?
      • Are there frequent on/off cycles, or is the fixture typically left on for extended periods?

      Failure-Specific Details

      Failure Symptoms:

      • What specific issue is occurring (e.g., flickering, no light output, uneven illumination)?
      • Is the issue constant, or does it occur intermittently?
      Timeline of Failure:
      • When did the failure first occur (e.g., immediately after installation, after months of use)?
      • Did the failure occur suddenly, or was there a gradual degradation in performance?
      Component Behavior:
      • If the fixture is flickering or dim, does it vary with input voltage or control signals?
      • Have you observed any unusual noises, overheating, or physical changes (e.g., discoloration)?
      Comparison With Other Units:
      • Are there other fixtures of the same model installed in the same location?
      • Are those fixtures experiencing similar issues?

      Troubleshooting and Testing

      Initial Troubleshooting:

      • Have you replaced or tested any components, such as the driver, power supply, or wiring?
      • Have you verified the input voltage at the fixture matches the specified range?
      Operational Testing:
      • Does it work correctly if installed in a different location or using a different power source?
      • Have you tested the fixture without dimming or control systems to isolate the issue?
      Visual and Physical Inspection:
      • Are there visible signs of damage to the fixture (e.g., cracks, water ingress, burnt components)?
      • Are the connectors, wires, and terminal blocks securely fastened?

      Additional Information

      Maintenance and Handling:

      • Has the fixture undergone regular maintenance or cleaning?

      • Has the fixture been relocated or handled frequently since installation?

      Other Environmental Events:

      • Has the location experienced any recent power surges, outages, or lightning strikes?

      • Is the issue related to external factors, like nearby heavy machinery or unstable power grids?

      Supporting Evidence:

      • Can you provide high-resolution photos or videos showing the issue or failure in action?

      • Are there installation or maintenance logs available for review?
