Thank you for viewing this item. I used this at home for almost 40 years, until March 2024, after which I removed and stored it. It was used in a room with little foot traffic and limited sunlight, so it hasn't deteriorated much for its age. I think it can still be used for a while, so I'm putting it up for sale. It has been cleaned. Product Specifications: (From HP) ◆ Width: 395mm ◆ Length: 705mm ◆ Height: 101mm ◆ Weight: 4.8kg ◆ 4.5 to 6 tatami mats (approx. 7.4 to 9.9 square meters) ◆ Pull switch (3 lights → 2 lights → small bulb → off) Product Contents: ■ Main unit (integrated with adapter) ■ Mounting bracket (with 2 screws and 2 bolts) ■ Shade ■ Spare (3 fluorescent lights [white], 2 glow starters, small bulb) ※ The main unit has three daylight fluorescent lights (18W) installed. How to Install: ※ First, you need to attach the bracket to the ceiling to secure the main unit. ① Drill two holes in the ceiling for the screws. (When deciding where to drill, you might want to decide the direction [vertical or horizontal] in which you will install the lighting fixture.) ② Tighten the screws to attach the bracket. ③ Loosen the screws on the bracket to some extent. ④ Secure the main unit to the bracket. (Push the main unit up so that two of the small holes around the large hole in the center of the main unit fit the two screws. Once they fit, rotate the unit slightly to secure it. Tighten the screws to firmly secure the main unit.) ⑤ Attach the shade. (Press the tabs on both sides of the main unit inward.) ※ The shade is not completely fixed, but it's fine if it's attached to the main unit and level. Things to understand before purchasing: ● This is a used item, so there may be some scratches and stains that are difficult to see in the photos. ● Although the operation has been confirmed, including the spares, the replacement date of the fluorescent lights is unknown, so the remaining usable lifespan is unknown. ● If, by any chance, it cannot be used, cancellation is possible. However, please note that returns are not accepted. The shipping method may be changed to Yu-Yu Mercari Bin. This is a limited-time listing until 23:59 on March 18th. If you have any questions, please feel free to comment. Immediate purchase without comment is also welcome. Thank you for your consideration!
