They are very bright.  I like all the space they freed up on my nightstands.  I was able to install them higher than where the original lamp shades were. They are about the same size shade wise I had before.
No I have working room under it the lights. Plus more room for 30oz yeti cup knockoff.

A tip for install... Put on the lower side screws first when mounting the lamp. You will want to do the top first since its so easy,  but no...
