This light is nicer quality than I expected and heavier. The only reason I gave it 4 stars instead of 5 stars is because the ad says it has a step-less dimming feature which I cannot access nor do I think exists. I was unable to find any information on how to access that feature through the site or through the instruction pamphlet included in the package. The knob clicks with each turn. Each click turns the light on or off, and then the next click turns on a different lighting temperature. The knob does press in slightly but I found this doesn't change anything with the lighting. The shades arrived flat and need assembly. They clip onto the rings included with a velcro closure. I love these shades, they are easy to assemble, strong, stylish, and good quality. The assembly is easy but must be done in the appropriate order so as to adjust the cord length. The height of the top lamp arm is 80" and the shade hangs lower than that. Overall I would recommend this lamp.
