I've had very bad luck sticking LED lights on various surfaces. I've tried both mounting squares that come with the lights and separately purchased double-sided mounting tape but the longest that they stay on is a week.
The lights are really lightweight (cheapo plastic pucks several inches in diameter) so the weight shouldn't be an issue. The surfaces I tried are smooth inside walls of a cabinet and the underside of a steel shelf; completely clean and dry so incorrect application shouldn't an issue either.
I do need the tape to be removable - I don't mind using a goo remover to remove traces of adhesive but I don't want to permanently damage furniture.
Thanks for your help!
