Choose fixtures that survive rain, washdown, and cold. What “wet-location” really means, plus heater and enclosure notes.
Last updated: October 2025
Wet vs damp, IP & NEMA
Wet-location fixtures resist direct water exposure; damp-location handle humidity/condensation. IP/NEMA ratings define enclosure protection; pick what your site conditions demand.
Heaters & cold-weather tips
Cold temps reduce battery output—use heater kits or cold-rated batteries to maintain 90-minute runtime in freezers or winter climates.
Housings, gaskets & hardware
Look for gasketed housings, corrosion-resistant hardware, and UV-stable plastics or coated metals for marine/coastal sites.
Placement & aiming outdoors
Mount to minimize direct spray and wind-driven rain; aim heads for path coverage and consider glare at doors and ramps.
FAQ
Can I use indoor units outside under a canopy?
Only if they’re listed for damp in that location; true outdoor exposure calls for wet-location listings.
