Can Wind Set Off Security Light?
A PIR sensor can't see moving air — but a sun-warmed branch swaying across its detection zones looks exactly like a person walking past. Wind doesn't trip the light; it trips whatever the light is aimed at.
Why Are My Pool Lights Flashing?
A Class A GFCI won't trip until 4–6 mA of leakage — meaning a water-infiltrated fixture can flicker for quite a while before the breaker decides to act.
What Causes Landscape Lights To Flicker?
Older magnetic transformers need a minimum wattage load to regulate properly — swap in all-LED fixtures and your system can flicker simply by drawing too little power. It's one of several causes that only appear once halogens are out of the picture.
Do Outdoor Lights Need A Junction Box?
Under NEC Articles 411 and 725, low-voltage landscape lighting splices don't need a junction box at all — but that exemption vanishes the moment your circuit runs at 120V.
How Far Can I Run Landscape Lighting Wire?
Run 60W of lights over 50 feet on 14/2 and the math says your fixtures will dim. One formula tells you which gauge to use before you bury anything.
How To Adjust Dusk To Dawn Light Sensor?
Cover your dusk-to-dawn sensor with your hand and wait — that five-minute pause before the light responds isn't a fault, it's a built-in delay designed to prevent rapid cycling.
Can You Add Motion Sensors To Existing Outdoor Lights?
Most PIR sensors treat the wall switch as optional — the sensor and your existing fixture are two separate things, and splicing one in rarely means touching anything beyond the junction box.
How To Make A Motion Sensor Light Stay On?
A rapid on-off-on flick at the wall switch can lock many PIR sensors into permanent-on mode — no tools, no rewiring. It's built into the sensor's internal logic as a mode-change command.
What Gauge Wire Do I Need For Landscape Lighting?
Run 60W of lights across 50 ft of 16/2 wire and you'll lose 2.72V before a single fixture even turns on. That's not a wiring quirk — it's why gauge choice quietly ruins otherwise well-planned installations.
Can You Wire Two Motion Sensors To The Same Light? Wiring Diagram
Daisy-chaining two PIR sensors in series means both must trigger simultaneously — so approaching from one direction leaves the light completely off. Parallel wiring is what actually gives you two independent controls on one fixture.
