I have shelving in my garage and put them on alternating sides zigzag to illuminate as I walk through. Once eyes are dark adjusted it works very well. You can literally walk down a dark room and it lights as you go. Sensors are basically 45degs to their side but sense say 10ft distant, and light after a little under a second, so suits aligning placing on the shorter side of a rectangular space. The light spreads wider light than the sensor reacts to.
My garage Eufy lights are stuck on to shelves. I also have one on wall illuminating inside of freezer and refrigerator.
I ordered some more to fill out some darker corners. The current price is lower than the last discount code.
My APC does router modem wifi phone for 12 hours. Here the most common cause of outages is winter storms pulling down branches. In California its a wet season after 6 months of dry so trees which aged in summer just fall over in wet ground, old branches fall, etc. So blackout in winter type problem, and when it happens it happens in dozens of places all at once each individually needing a repair so 12 hours is a typical. For some reason the local utility power is overhead weaved parallel through all the trees, almost designed for maximum outages.
Eufy remote controlled switch for manual or timed on/off of lights. The Eufy plug-in lights to come automatically at night when there is power, and the Eufy stick-on battery lights for dark no-power movement detecting lights. Anker LC40/90/130 for moving around, it becomes a reasonable total system for all the situations I can imagine.
