I am making a built in bookcase and am planning on lighting it with LED tape lighting. I can source 10m of the lights at Lee Valley for $139 or from Amazon for less than a tenth that price ($12). Both have the same specs, but I have no idea about relative quality. (It’s not like LV makes these, like they do their tools, or at least I can’t imagine they do...) Anyone have any experience with these - or other - options?
