A little complicated to install due to the construct of the "glass tube inside a tube", but careful study of the directions and a bit of patience (as well as an extra person to hold fragile pieces in place) is worth it as the final product looks great.  Plan on at least 30 to 45 minutes for each light to install.

Length is completely adjustable prior to install.  

Pros: Good value, beautiful finish
Cons: Complicated installation and fragile materials
