The sunlight shouldn't affect it. I can't think of any way that it would. "I have solid green and orange LEDs, " But that doesn't mean that they are aligned correctly and the slightest vibration could throw them off. They can be close enough to make the LEDS light up while the door isn't moving. Watch the LEDS while it is closing and see if they blink. Use a string or straight edge if you have one that is long enough, or you can also use a laser level. Using a string is easiest to describe, so I will use that example. I hope you can figure out my instructions! It's easier with two people but if you are doing it alone. Tie the string below one sensor and pull it over the top of it, then over the top of the other sensor. The string should lay flat across both. Adjust if needed. Then tie off to the side of one and pull across the other and adjust that axis also. Repeat step one in case the adjustment moved the other axis. I hope this helps.

I LOVE my motion-triggered light in my pantry /laundry room. It does exactly what you'd want it to do: When someone approaches carrying a load of laundry or an armload of groceries, it turns on automatically. Less evident, but also important: It turns OFF after ten minutes or so. Prior to installing this, this light was left on all too often, and no one'd notice it 'til we sat down to watch TV and realized that it was causing a glare from across the kitchen. The only problem we ever have is that occasionally someone turns off the lightswitch, and then the lights won't turn on. When that happens, I stand there like an idiot waving my arms, trying to get it to "notice me" . . . then I realize what's happening, and I reach over to turn on the lights. I don't think I"d be happy with a door jam style. Our door isn't always closed, so I think I'd run the light needlessly. I don't know which type costs less, but my husband installed ours himself, and I don't think it cost more than $25-30 . . . though I am guessing. He didn't act like it cost much of anything. In our new house, we will have motion-sensored lights in several places: - Garage - Hallways - Closets - Laundry - Pantry - Bathroom night lights, if that's possible -- I don't really want the master bath light to come on automatically because I wouldn't want the light to spill into the bedroom during the night - Maybe some outdoor lights? Uncertain.

Thanks jimisham, I did the search you mentioned but I keep getting *mechanical* spring switched lights, not motion sensor lights. I have young children and several large walk in closets. I don't want the lights staying on when the kids leave the closet doors open or worse, the lights going out if the door gets closed with a child inside. If you ask my kids about their favorite part of our new house they'll tell you, "the Harry Potter room under the stairs!" Thanks for taking the time and making the suggestion. Even though the the automatic closet light switches won't work for us they're a great low cost solution and may work very well for others.

> not ALL the diodes could have died Many LED retrofit bulbs, especially the cheap ones (which is pretty much all of them now), have all the LED chips in series across a fairly simple power supply. If one LED opens, all of them stop working, just like Christmas tree lights from 70+ years ago. There are ways to keep a single LED failure from killing the light, but they add cost, so they don't often get implemented. But that probably doesn't matter. The power supplies in those $2 bulbs are built with the absolute cheapest, most marginal electronic components the low-bid fly-by-night Chinese sweatshops can make. Therefore most often it's a failed power supply component that takes out your bulb, not an actual LED chip. FWIW, I know guys who cut open failed LED retrofit bulbs and rebuild the power supplies with better components. Or sometimes salvage parts from 2 or 3 units to make one working one. Great if you have the time on your hands, I guess. Remember when LED retrofits cost $30 or more and claimed an average life of 50,000 hours or better? Now they cost a couple of bucks, but average life is more like 20,000 hours. I saw one a while back that claimed (in small print) a 15,000 hour lifetime. Hey, wait a minute. Now that I look at your photo, I don't see replaceable bulbs in that luminaire at all. Isn't that a premade LED-only fixture? Something doesn't add up here.
