Item is only as good as the seller.

The lights I have installed as downlights in the kitchen. Of course you do not replace the proper lighting. But they are bright enough to work on the countertop. And when Effect lighting really very good. The individual lamps can be screwed under the wall cupboards, the screws are at it, or stick. The pads are also included. I wanted to screw prefer, however, did not get open the lamp. In order to screw tight, you have to open the lamp, unscrew the cover of the lamp to the cabinet, and then close the lamp again. These steps are not explained, so I called the seller. Sorry, but did not know it, but promised to inquire into the workshop, and to call me back. He has, however, not made, so I had to glue the lamps yet. Until now it holds.
