I use the V-Channel Led Aluminum Profile to mount LED strips. These holders allow you to make a rigid structure that can be applied to the roof of an enclosure or underside of a shelf with command strips. Because they are puzzle pieces you can mount as many rows of LED as you like, and cut the channel to any length to fit. Zip ties and glue mean this goes nowhere once attached :)
