This is a listing for a set of two Edison Smart mini spotlights with adjustable beam angles. They are for duct rails and are white. Purchased new and used for only about 10 months in a non-smoking room, the condition is very good. The instruction manual is also included. These are smart lights compatible with Amazon Echo (Alexa) and Google Home, allowing for dimming and color adjustment. The adjustable beam angle allows for pinpoint lighting or general illumination.
