I like my lamps and the directions that tell me that i can use a 3 way bulb.  The bulb seemed to be a good quality but i purchased a different bulb of the same kind but with a with a warmer light tone.  I like the square shade but the armature sits lopsidedly on the base for the bulb so i have had to stuff a little something under the ring to get the tilt out of the shade.  Thanks for the amazing choice in products.  That is greatly appreciated.  It took looking at over 2000 lamps to finally find one i wanted to live with.
