The light these give out would work well enough for small, dark spaces, however it is the problem of mounting them in such a way that the magnetic switch is close enough to work (ex. turn the light on or off on demand as when a door or drawer is opened) and yet have the light mounted to face a functional direction. I find that the magnet has to be about 1/4 to 1/3 inch away from the light and directly in front in order to work, thus the photo illustrations of the lights as positioned in the drawers, toolboxes, cabinets, etc. simply cannot work for all practical purposes. Therefore I find that I have simply wasted the money that I spent to illuminate my drawers and cabinets. If these lights could be turned on by pressing a switch, they would be far more functional. More detailed information about how the lights operated would have been much appreciated before I purchased. It's a great idea but lacks some practicality.
