Yes, that's correct. Knob on the wall plate has a smooth turn and a click to dim and then turn off. Purchased this at Restoration Hardware. Bulb is 40 W, which seemed low to me, but then I googled and discovered that 'ideal reading light' prior to bedtime is 40-60W. I guess its perfect. I'm still adjusting to the 23" it sticks out from the wall.

Be aware that this sconce has a lengthy rod. I used them in my project and this picture of the sconce misled me. When I wake up, I have to slide myself half way down the bed then I can get out to avoid getting jabbed by the end of the rod.
