Westek OMLC3BC-4 OMLC163BC Motion-Sensing Light Control, White

It comes immediately after I enter the garage. I like the fact that it stays on for 10 minutes. East to install.

Love it, screws into regular light to turn any porch light into motion detected light. Best thing ever without having to rewire a light.

Like many motion sensor sockets, this model relies on a spring-loaded pin at the center of the socket-base -- the part that screws into the lightbulb socket. This pin allows the unit to be unscrewed a little, to reposition the sensor housing. The housing itself extends from a limited-movement ball socket so you can rotate and tilt it a little in any direction. The result -- unscrewing the unit from the wall or ceiling socket where it's mounted, and swiveling or tilting the sensor a little -- is that you have a decent chance of "aiming" the sensor in the required direction. (Some reviewers apparently didn't notice the spring-loaded pin feature.)I was able to get it all positioned so it triggers when I enter the store-room where it's mounted. But with a big LED multi-panel light dangling from it, I'm not really happy that I can't screw the unit fully into the ceiling socket. Using the "unscrew a little" solution for positioning the sensor leaves the unit less than fully fixed to the ceiling socket.One would think that by now, with hundreds of schemes for making motion-sensor sockets, there would be a more complete and robust scheme for positioning the sensor. I installed this unit to replace a concentric sensor socket that seemed to have a 360 degree field of view, but was unable to detect motion 90% of the time. This Westek unit is very sensitive, and works 100% of the time. Unfortunately, it has no adjustments for sensitivity, ambient light, or on-time. It ignores ambient light (which is not a problem in my windowless storeroom), is very sensitive to all motion (which is what I needed), and stays on for 10 minutes with no adjustment to change duration (which is OK, but I would rather have it time out after 1-2 minutes, since it re-triggers at the slightest movement).

Outstanding product. Some reviews are critical about the fact that you cannot use this with any type of covering over the light, but this is clearly in the description. I use this at my back door; I would much rather have a very safe well-lit entrance over a decorative fixture over my light. This is an outstanding product; it does exactly as it should do. It’s extremely easy to install, and if you want a motion sensor light that you can depend on, this is the product.

I bought this for use in our food pantry. We have used the First Alert PIR725 Motion Sensing Light Socket in our garage which has lasted about 10 years and is still going strong. We couldn't use the First Alert sensor in our pantry because of the angle of the sensor was too high to detect motion when the pantry door was opened. The nice thing about the Westek is you can manually adjust the sensor to detect entry into a room or closet. The Westek worked fine for 2 weeks and then quit working. It did make a clicking noise every time the light came on, which may or may not reflect normal operation. I think what may have caused the Westek to fail was that the light bulb burned out while the light was in the on mode, and the unit never reset itself, most likely a design flaw.I opened the unit to see if there was something like a reset button, but I found no moveable parts. As it turns out, the unit is secured with security screws (see attached photo), so a normal flat head screwdriver won't work. I had to buy a 1" long 1/4" #4 security spanner bit (looks like a 2-pronged fork) to remove the screws.I didn't purchase this from Amazon directly because Amazon wasn't selling it at the time (they are now). The vendor did send me a replacement which I haven't tried yet. The unit does come with a 5 year warranty if you want to go through the hassle of returning it to the manufacturer. As you can see from reading the other reviews, you may or may not wind up with a long-lasting unit.
