High Mast Light Failure Modes (Prevention Guide)

Where This Guide Fits

Top failure modes (what usually goes wrong)

  • Surge damage: SPD level not specified or not installed correctly.
  • Sealing/IP failures: water ingress at cable entries and junction points.
  • Corrosion: wrong protection system for coastal/industrial environments.
  • Commissioning gaps: aiming not verified, protections not recorded, no acceptance records.
  • Silent substitutions: components changed without approval; no traceability.

Evidence gates (pass/fail)

  • Photometrics pack (IES/LDT + simulation outputs)
  • Surge protection spec + evidence
  • Sealing/IP evidence + inspection records
  • Corrosion protection requirement + records
  • Commissioning checklist + acceptance records
