These light up nicely, but me being an engineer, What I found difficult for under counter mounting was the cord ends going into the units should be horizontal for flat/ low profile mounting. Most won’t mount these with the rotating lamp hanging below the counter lower ledge. The linking cords and power cords need to be useable from both sides. This forced me to mount the lamp facing the backsplash with the power cord coming from the right hand side. The design engineers need to do better building in mounting, wiring versatility and predictability. Make the lamp that it can be disassembled to swap the outlets from side to side?
