I just went into the garage to make something up for you in less than a minute...The fixture itself (for the T5) has nowhere to attach anything. No hooks, no holes. I don't know about you but I am not skilled enough to try to make my own holes in a metal fixture and void the warranty.
take two coat hangers - the old wire ones. Cut and bend them like this. Hook it around the sides of the fixture towards each end and hang!! (Building a new enclosure right now in the background)
