I installed 18 in a large room that is both a kitchen and living room. In the family room I set the color temperature to 2700K, fireplace light, and above the kitchen to 5000K, sunlight. The frames are very dark bronze and tend to look black. I have them on dimmers with no problems. We mounted a new ceiling on 2x4 boards. The electrical box for each light and the light itself are less than 2 x 4 (about 1.5 inches) thick and fit in the narrow space between the old and new ceiling. The lights have an even illumination through a diffuser with no brie fighting spots.
