This light is completely enclosed with beveled glass, on the sides and the bottom. This was important to me due to barn swallows liking to hang from my chain light and leave droppings. Lots of dropping... They can not hold on to anything on this light. Very easy & quick to install and packaged extremely well.  Best of all, no dropping since the light was installed! All pieces were there and they way it was packed, did not have to worry with anything being broken. Thank you to Ainsworth!
