I have previously bought several of these 3 inch sizes for external ceiling lights and they work great. I just bought a four inch WF4 for a closet. I was hoping the dimensions were wrong in the description as they were the same size as the six inch WF6. I took a risk thinking they would be smaller than advertised which is what I wanted. In fact, they are smaller. WF4 dimensions are as follows: overall diameter 4-11/16 and the lantern (lens) 3-1/8. I have everything on dimmers and so far they have worked flawlessly.
