Safety and Security — FAQ
How many lumens do I need for a basement motion sensor light?
Unfinished basements need 10,000-15,000 lumens for 500-800 sq ft. Finished spaces require 3,000-5,000 lumens. For large basements, use multiple fixtures rather than one overpowering unit to eliminate shadows.
What's the difference between PIR and microwave motion sensors?
PIR (passive infrared) detects body heat and works best for human movement. Microwave sensors detect motion through walls but trigger more false alarms. For basements, PIR sensors provide reliable activation without pets or HVAC interference.
Should I choose hardwired or plug-in for basement installation?
Hardwired flush mounts offer clean aesthetics in finished basements. Plug-in units work best for utility rooms or renters. Screw-in bulbs provide the easiest upgrade path for existing fixtures without electrical work.
Can motion sensor lights be used in damp basements?
Most indoor-rated lights handle typical basement humidity. For consistently damp spaces, look for IP44+ ratings. Ensure good ventilation around fixtures to prevent moisture buildup in electrical components.
How do I adjust motion sensor sensitivity and duration?
Most units have dials or switches on the fixture. Sensitivity controls detection distance—lower settings prevent pet triggers. Duration sets how long lights stay on after motion stops, typically 30 seconds to 10 minutes.
What's the lifespan of LED motion sensor basement lights?
Quality LED fixtures last 25,000-50,000 hours. Motion sensors themselves typically function for 5-10 years. Heat is the main degradation factor—choose aluminum housings over plastic for longer life in enclosed fixtures.
