Hanging a 4 foot fluorescent light is the best way to fix small dark areas like Garages and outdoor sheds. It is called a shop light in the field sometimes. If you have anything larger, I would switch to 8 foot and use reflectors for added light density. Jack chain is best for hanging because it will adjust very easy. The cage protectors are only needed if you are worried about something hitting the fixture on a regular basis. Most of the time those are used in commercial/industrial environments. The basic material I list at top of page is sometimes a bit off because I am looking at it that many devices can be installed more than one way.
