These glass cover on these are quite delicate and I'm concerned that they are not held too securely by the hinges.  They wobble in place a bit and won't like perfectly straight in line with the interior bulb which kind of drives me crazy.  Based on other reviews I'm afraid if I tighten the hinges the cover may break.  Also, the glass portion of this is strangely long.  While I've received compliments on them and they produce a nice industrial look I'm not too impressed.
