These LOOK great, I would give them 5 starts for attractiveness and quality. However, the glass covering on the light is very slim.   I can't imagine any bulb but  chandelier bulb fitting inside.  Defnitely not a regular bulb happeniing in there.  The instructions had a picture of a small square bulb, but it was nothing I've seen before and who wants to sign themselves up for buying special bulbs or non-LED if you can't find them?
