Inspection

Inspector Detail

Common issues

  • LED driver failure, especially after voltage spikes or poor earthing of the supply
  • Gasket hardening or cracking over time, allowing moisture ingress
  • Corrosion at housing seams or the cable gland in humid or salt-laden spaces
  • Gradual lumen depreciation reducing effective illumination below the design level
  • Cable gland or terminal corrosion causing intermittent operation
  • Condensation forming inside the diffuser on fittings mounted in unheated spaces

Inspection checklist

  • Visual check of housing, lens/diffuser and gasket condition
  • Check light output visually, or with a lux meter, against baseline for critical spaces such as the engine room or escape routes
  • Check cable gland tightness and earth continuity
  • Confirm the driver gives steady output with no flicker
  • Check the mounting bracket for corrosion or looseness
  • For fittings on an emergency lighting circuit, verify changeover to the emergency supply

Service intervals

Lens/diffuser cleaningevery 6 months, more often in engine room or exposed deck areas
Gasket and seal inspectionannually
Driver/module replacementon failure - LED drivers are the most common failure point and are not normally replaced on a fixed schedule
Emergency lighting function testmonthly, if this fitting is on an emergency lighting circuit

Typical wear limits

Lumen maintenanceLED fittings of this class are commonly treated as end-of-life around L70 (70% of initial output), though the exact figure depends on the driver and LED chipset used - confirm against the datasheet rather than assuming a fixed number

Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.

Critical spares

  • LED driver module
  • Gasket/seal kit
  • Lens or diffuser cover
  • Mounting bracket
  • Cable gland set

Safety

  • Isolate the circuit before opening the fitting - a local switch does not always fully de-energize it
  • This fitting is rated IP44, a splash-proof rating, not a hosed-down or fully submersible rating - it is not suitable for positions exposed to direct washdown or green water despite being marketed as marine lighting
  • Confirm the actual zone rating before use anywhere hazardous area classification applies - a standard fitting of this type is for safe/general areas, not Zone 1/2, unless the specific ATEX/IECEx-certified variant is confirmed

Class survey

General lighting is normally checked for basic function during survey. Fittings forming part of the emergency lighting system are subject to a documented periodic test and are checked more closely at survey, including changeover time to the emergency source.

Estimated lifetime: Marine LED fittings of this class are commonly rated by manufacturers in the region of 30,000-50,000 hours to L70, but actual life is strongly affected by heat, vibration and power quality, so treat this as an order-of-magnitude figure only

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — attach it below or send it as a reply to our confirmation e-mail.
