In this system we are lighting a bookcase. There are two main methods when it comes to lighting a bookcase. You can run the LED strips horizontally across each shelf like we did in this design. The other option is to mount the LED strips vertically going up each column holding the shelves in place. How you decide to mount the LED strips will come down to your personal preference.
