Thank you for viewing. I purchased this from a model room, so it was included with the purchase. Therefore, the purchase date is unknown, but I've only used it for about 6 months since moving in. I've only used it for a few hours. Manufacturer's official website: https://www.yamagiwa.co.jp/products/324l1003l/ YAMAGIWA BAUMN® Ⅱ (Discontinued) 324L1003L BAUMN is a voluminous lighting fixture whose simple shape matches the fine, random pleats. The inside is designed in a bowl shape, and the entire fixture emits light from the lamp installed inside. The light source is not visible, and it warmly envelops the space. Total coordination is possible by combining it with the pendant and stand from the same series. BAUMN Ⅱ features a pleated design. The edges of the pleats are not trimmed with ribbon, resulting in a clean, modern detail. When lit, the pleats beautifully illuminate, creating a modern design. ・Main Spec Light Source Type E17 LED bulb 60W type (LDA6) x 6 ・Power Consumption 37.2W ・Dimensions Height: 280mm, Width: φ600mm ・Weight/Mass 3.7kg ・Material/Finish Steel painted finish, steel chrome plating, resin, fabric (pleats) ・Installation Method Easy installation type
