I saw this lighting rig on a music video and it has had me intrigued as to what it is called. I am looking into building one but I would like to do more research before I jump into anything.
It looks to be three tube fluorescent lights in a triangle.
Looks to me like the grown-up version of a ring light, except made into a triangle because straight tubes are available. I doubt that there's any magic behind its engineering other than "hey, what can we do with these tubes" and it turned out to work pretty well =)
If you wanted to experiment cheaply I wager than most 3D modeling packages can simulate a triangle made of tubes like this so you could previz what a real setup would look like.
If you want a more photography-oriented tool like this, look at the SaberStrip. I've never used them so can't offer any experience details.
