This is a ceiling light for a duct rail, compatible with smart speakers like Amazon Echo (Alexa). It can be controlled by voice, smartphone app, and also with a separately sold remote control. While there are previous models without indirect lighting, this one features the latest 3-WAY dimming function. You can adjust the brightness and color temperature from daylight to warm white, and it offers three modes: ceiling light mode (down), indirect lighting/night light mode (side), and all-lights-on mode (all), making it a very user-friendly ceiling light. - Manufacturer: EDISON SMART - Type: Down Rail Ceiling Light - Color: White - Model Name: Treo with Arm - Features: Wi-Fi compatible, 3-WAY dimming - Power: Max 200W - Size: 2700-6500K, 2000lm - Included: Instruction manual Please note that this item is considered used, as it has only been opened for inspection and has never been installed or used.
