White/Black AWG lamp dimmer extension cord with switch dimmer cord Switch Dimming Cable Light Modulator Lamp Line Dimmer (Black)

It worked fine. And it was not very expensive. The only reason I gave it 4 and not 5 stars was that it seemed a little flimsy. And the circular disk that you turn to raise or lower the intensity of the light was not as easy to turn as I would like.

Hmm...It dims but only the last 10% of the rotation and the voltage is low at max so lights are dim.

came with loose wires - needed to take off plug to add it - no instructions - terrible
