This light has a tap-touch dimmer.  Unfortunately, it will not work with a light switch, so I will be returning it.  Also, I didn't realize when I purchased it that the "bells" of the lamp are actually covered in clear plastic.  This was weird to me.  I guess I can see it when I look closely at the picture, but it's definitely not what I was expecting.  The necks of the lamp move quite smoothly, much better than the stiff goose-neck lamps I've used in the past.  The built in bulbs cast a bright, cool light rather than a warmer hue.  I didn't like this, but I know some people prefer this.
