I need some help with this one. If you have a closet that is 24" deep can you install a light in there? I've read the codes and it gets a little confusing. If you use a dome covered pullchain, you have to be 12" from the egde of the self (the selfs are usually 12") and 6" from the other wall. You will need a 36" Closet to do this. A can light can be 6" from edge so with that you need a 30" closet. Am I just messing this all up or am I right, b/c all of the prints I get have 24" closets with lights in them.
