They are solid not flimsy.  Love the option to hardwire or make plug in.  I choose the plug in option however since the wire was bright yellow I then used cheap café curtain rods spray painted to match, with the ends removed as my cord covers.  I threaded the wire through before attaching it to the light.  I am more than pleased with the results.  They are not dimmable as I thought was mentioned in a previous review, just on and off.
