The description on Wayfair said to use E26/Medium (Standard) Base bulbs. I bought those, as y ou can see. They DON'T FIT. Wayfair has done this before - given wrong information on a product. You need just regular bulbs - I used 2 - 25 watt soft white bulbs and they are perfect.  WAYFAIR - YOU NEED TO CORREC THIS INFORMATION ON THE WEBSITE FOR THE LIGHT FIXTURE I JUST REVIEWED.
