## Description

Westek OMLC3BC-4 OMLC163BC Motion-Sensing Light Control, White - Flood Lighting - desertcart.com

Review: Good product. - Installed and have been using for a month now. Works as expected.
Review: UPDATED to 5 stars - This would often work as intended - great! Just as often, it would turn the light on when motion is detected, then simply not turn off - totally defeats the purpose. This 'not turning off' problem seemed worse when using a CFL, despite the fact that the item description says it is compatible with CFLs. After just under a year, it ceased functioning altogether. It has a 5-year warranty, so I guess I'll ship it back to them. Maybe the replacement will work properly. I'll update. UPDATE 12/06/12: manufacturer shipped a new one. This one works perfectly. Hopefully the first one was a fluke. Based on this, I upgraded my rating from one star to three. UPDATE 02/10/14: Based on the great performance of the warranty replacement that was sent to me, I bought another for a hall closet. Works perfectly. Maybe the first one was a fluke. Nevertheless, based on the two that I have now, I upgraded my rating from three stars to five. Highly recommended. UPDATE 01/14/14: The one I purchased for the hall closet ceased functioning altogether after less than a year. Based on my experiences, I would say that this item is very unreliable. It's a good thing that it has a 5-year warranty. I shipped it back to the manufacturer - again on my dime. After an extended period of time, the manufacturer shipped a new one. Again, this one works perfectly. Based on this second failure, I am downgrading my rating from five stars to one. If you are looking for a motion sensor that works perfectly - until it soon doesn't - then this is for you. If you are looking to not have to go through the trouble of installing a new one every year or two, move on to something else. I just wish I knew what the alternatives are, so I can purchase those after the warranty period runs out on these.
