I love the extension arm which is directional & gives good light to my reading area. I also love, love the small 5" base that fits on the top of a tall, narrow bookshelf that sits next to my loveseat. The push-button on/off switch is very low-key & in a place that's not at all obvious, yet very easy to locate & operate. It's totally industrial looking aesthetics is just what I was looking for! Good find Wayfair!
