This is a ceiling light for a duct rail from Art Work Studio. Price: ¥12,100 (including tax) / 1 piece I purchased this in November, but it didn't suit my home, so I'm selling it. Color: White It's almost new, as I only tried it out. I threw away the box, so I will wrap it in bubble wrap and ship it in a recycled cardboard box. Despite its compact, palm-sized design, it achieves surprisingly bright illumination with a high-efficiency LED equivalent to a 100W light bulb, making it suitable for various scenes, from homes to shops and facilities. You can change the color of the light by switching the switch. For more details, please check the Art Work Studio website. Search for "AW-0551E".
