I replaced an outdoor, motion detected flood light with a LED
dusk to dawn light. Prior to switching, a wall mounted light switch
by our front door controlled the light. After installing the LED dusk to dawn light, however, the light switch will not turn it off. It does turn itself off when it's daylight, though. So, I thought maybe it was a bad light switch, so I was going to replace the old wall switch with a new one. Inside the box, were 2 black wires connected to the switch, 2 ground wires connected to the switch, and two white wires connected to each other with a wire nut. I used an AC tester to check the wires, and one black wire was hot (connected to bottom pole of switch), and all the others were not hot. When I flipped the light switch, both black wires tested hot, which makes me think the switch was working. So, before I zapped myself, I decided to flip the breaker off, so I did. I rechecked the wires, and none of them were hot. So, I then replaced the switch with a new one (single pole). I wired it like the old one was. I flipped the breaker back on, and waited for sparks. Everything seemed fine, but the light still stayed on, regardless the position of the light switch. Since I wanted our Christmas lights to stand out, I decided I'd just throw the breaker, and not use the light. Except when I flipped the breaker off, the light still stays on. There are 3 outdoor lights on the same breaker that I can tell, and one of them does turn off when I throw the breaker, but the other two (same brand/model of light) stays on. All of the wall outlets
in the living room are also on the same breaker. I'm confused. Thanks!
