Panasonic LK04083WZ Ceiling-Mounted Interior Duct, Slide/Rotation Type, U-Light System, 1448mm Purchased this March. Originally planned to install multiple pendant lights, but ended up using a ceiling light instead, so this has been unused and left untouched. I have not used it even once. I opened the box to take these photos. The warranty is also included.
