I saw this at a local B&M store at a significant price, so went on amazon and bought about a dozen for a more reasonable price.
I made the mistake of not turning off ambient lighting when I first plugged it in as it would no stay on, But once the room was mostly dark. The path light worked perfectly. You can plug it in with the led pointing up or down on a standard wall receptacle.
To my eyes, its not too yellowish or too blueish for those who remember first gen white leds.
Motion detection is pretty good range wise (activates about 12ft away, as long as you are in the zone of detection, but they could improve the degree of the detection zone (its not 180, more like 120 give or take 10 degrees)
