Wet-cleaned zones
Use this approach where hoses, spray, rinse-down or sanitation can reach the fixture.
Engineering Definition
What Is Washdown Lighting?
Washdown lighting refers to lighting selected for environments where water spray, wet cleaning or sanitation can reach the luminaire. Suitability must be verified against the exact cleaning process.

01 · Conclusion
Washdown lighting is selected for locations where water spray, wet cleaning or sanitation can reach the luminaire. Suitability depends on the actual cleaning process and installation, not a label alone.
02 · Applicable conditions
Where this guidance applies
Where this guidance applies
Start with the operating context.
Use the relevant conditions below to decide whether the topic applies to the installation being reviewed.
Food-processing support areas
Consider exposure from adjacent operations as well as direct cleaning of the immediate zone.
Equipment interfaces
Review the housing, cable entry and mounting points where water can collect or enter.
03 · Risks and exceptions
What can change the decision
What can change the decision
Check the exceptions before specifying.
These are common reasons a seemingly suitable product path needs further project review.
Unknown cleaning intensity
Pressure, distance, temperature and frequency can change the required protection path.
Chemical compatibility
Cleaning agents may affect seals, lenses, coatings and mounting materials over time.
Water traps
Poor orientation or inaccessible interfaces can retain water and complicate cleaning.
04 · Standards and evidence
Verify before approval
Verify before approval
Use controlled evidence, not assumptions.
Confirm the project requirements and current documents before making a suitability or compliance decision.
Cleaning-process record
Capture the water source, nozzle, distance, temperature, chemical and cleaning frequency.
Product documentation
Verify protection, material and installation information in current controlled documents.
Site requirements
Confirm the standards and approval process used by the facility or equipment owner.
