Lighting — FAQ
How long do motion sensor flood lights last?
Quality LED fixtures last 50,000+ hours (15-20 years). Motion sensors typically fail before LEDs—expect 5-10 year sensor lifespan. Solar batteries need replacement every 3-5 years. Hardwired units outlast solar by eliminating battery failure points.
Should I choose solar or hardwired?
Choose hardwired for primary security where reliability is critical. Solar works well for supplemental lighting, remote sheds, or rental properties where you can't modify wiring. Solar performance drops 30-40% in winter with shorter daylight hours.
What's the best mounting height and location?
Mount 8-10 feet high, angled slightly downward. Position to cover approach paths without triggering from street traffic. Corners provide maximum coverage area. Avoid mounting near heat sources or HVAC vents that trigger PIR sensors.
Can I adjust sensitivity and duration?
Most quality fixtures offer adjustable sensitivity (10-70 feet) and duration (5 seconds to 10 minutes). Look for stepless adjustment dials rather than fixed increments. Some models offer lux adjustment to prevent daytime activation.
Will pets trigger the motion sensor?
Adjust sensitivity to ignore animals under 40 pounds. Mount sensors 6+ feet high to avoid small animal detection. Some models offer pet-immune zones. PIR sensors detect heat signatures—large dogs may still trigger regardless of settings.
Do motion sensor lights work in extreme cold?
Hardwired units operate reliably to -20°F. Solar batteries lose 50% capacity below 20°F. Lithium-ion solar units perform better than NiMH in cold. Check operating temperature specs—quality units list tested ranges, not just generic claims.
