These look great. An electrician installed for me. The lengths are indeed adjustable. The bulbs are very nearly straight but they do lean slightly and electrician could not straighten them. It seems to be because of the angle they end up on after being screwed in ie the threading. My main complaint is that the shape of the glass shade is DIFFERENT from the photo on Wayfair. I bought these because they match shape of another fixture I bought for the bathroom down the hall. I believe I should get the actual fixture pictured. I will just accept the different ones I got.
