Lighting — FAQ
How many lumens do I need for garage security?
Single garages need 1500-2000LM, double garages require 2500-3000LM, and large properties benefit from 3500LM+. Motion-activated lights can use lower lumens since they're not constant. Consider 3600LM for driveways over 40 feet deep.
How long do solar flood light batteries last?
Quality lithium-ion batteries typically last 2-4 years with daily cycling. Performance degrades 20% after 500 charge cycles. Replaceable battery designs extend total unit lifespan to 6-8 years. Cold climates accelerate capacity loss.
Will these work in cloudy or winter conditions?
Yes, but runtime reduces 30-50% on overcast days. High-efficiency panels still charge in indirect light. Snow covering panels stops charging completely—brush them off regularly. Models with larger batteries compensate for winter's shorter charging windows.
What does IP65 waterproof rating mean?
IP65 means dust-tight protection and resistance to water jets from any direction. Safe for heavy rain and snow exposure. Not submersible—that requires IP67. The '6' is dust protection (highest), '5' is water protection (good for outdoor use).
How high should I mount solar flood lights?
Mount 8-10 feet high for optimal motion detection range and light spread. Too low creates harsh shadows and narrow coverage. Too high reduces motion sensor effectiveness. Angle heads 45° downward for best illumination of garage doors and driveway.
Do solar panels need direct sunlight?
Four to six hours of direct sun provides full charge. Indirect light works but extends charging time. South-facing mounting captures most sun in northern hemisphere. Avoid shading from trees, eaves, or neighboring buildings during peak sun hours.
