Document: Compared to wiring something, this is an amazingly elegant time and cost effective alternative/ improvement.Not sure about the price here. I paid less than $30 a set at my local warehouse club.
Got this to illuminate a closet. It worked very well for a while. Unfortunately it started eating through batteries. Was a great idea but think I will need to look for something with a longer life.
what you save in light bills and convenience, you will pay for in batteries, although the idea of this is tempting, they are an amazingly expensive light source. I got the top of the line Durecell Batteries to run these, and they all died within a couple of weeks, even though I only turned them on for an accumulated time of less than 1 hour.NO ONE SHOULD BUY THESE!
useless went out after 1 week, takes too many batteries, ended up paying more in batteries then product, in less then a month.
I bought these at Costco less than a month ago. At the most, they have a total of 2 hours of use. When I turn them on, in less than 5 seconds they dim to almost nothing. I am assuming they need new batteries which I will not install. 20 new batteries for only a brief time of use would be a very expensive monthly bill. They are being returned. Nice concept but weak design.
LEDs are bright enough to actually light something up! Hoping for decent battery life.
I liked them so well that I recommended them to my daughter. We both now have them in our kitchens. They are easy to install and easy to use. I am thinking about buying another set. BUT after less than 8 hours of use, they no longer work. I am extremely disappointed.....bad product.
I bought these for a gidt for my Husband and He put them in his Gun Safe. Now when he opens the door, all the lights come on and we don't need a Flashlight.
If they worked they would have been perfect. First off it was very hard to open to place batteries; secondly they worked for about 1 hour then faded and then they went out. Needless to say I wasn't happy.
I bought 3 packages to use inside an oak bookcase with glass doors that I'm using to display pottery. They give off plenty of light for this purpose. I bought them after having bad luck with a less expense product that I returned. I wanted lights that matched the bookcase as well as possible because you can see them.
Answer: no
