Do I really need ceiling box grounded?

I realize there are many posts about this, and I agree it's important. Based on my research, all I need to do is add a ground wire somewhere in the box and run it to the light? That seems too simple. Below is picture of what I'm dealing with. Name:  IMG_2305.jpg

How would you add the ground wire. Is that a metal box.

You do not ground a metal box by attaching it to the light fixture, you ground the light fixture to the metal box. The box is likely already grounded because the wiring method is likely steel flexible metal conduit or BX/AC cable. You can test this by using a meter or neon tester and reading from a hot/switch leg wire to the box. if the test light turns on, or the meter shows 120 volts, it is grounded. Install the light fixture as shown by the manufacture.

Be careful which fixture you try and install there. Many fixtures require 90 degree wiring, which that is not.
