IKEA Used for about 2 years. SKURUP x 2 units Ceiling track spotlight 3 bulbs, black TRÅDFRI 1st unit Starter kit (with remote control), Smart/Wireless dimming/color temperature adjustment (daylight white to warm white) 2nd unit Wireless dimming (no color temperature adjustment function, brightness can be changed) Sold as a set. Includes spotlights, bulbs, and remote controls, so you can use it right away. This item is used. Before listing, I have confirmed power on and basic operations (lighting, extinguishing, response), but due to the nature of smart appliances and electronic devices, • Usage environment (communication environment, compatibility with other devices) • Vibrations and temperature changes during transport • Deterioration of internal components due to aging etc., there is a possibility that malfunctions may occur after arrival, which cannot be completely ruled out. We ask that only those who understand this point and are satisfied with the item being used purchase it. We recommend resetting before pairing. *This product is a smart appliance (with communication function). • For pairing and setup methods, please check the manufacturer's official website and instruction manual. • Depending on the usage environment and setup method, it may not operate correctly. • We do not provide setup or connection support.
