【SOLKLINT Solklint】 A ceiling light with brass fittings and gray clear glass, 27 cm in size, perfect for interior design. 【TRADFRI Tradfri】 Starter kit, smart/wireless dimming white spectrum, E26 Plus batteries It didn't suit my home, so I installed it once and removed it after a day. You can use it right away as it's a smart bulb with ON↔️OFF and dimming functions, and batteries are included. Please refer to the IKEA website for installation instructions. I've disposed of the original box, so I will pack it securely in another box for shipping. Thank you for looking.
