Largest flashlight manufacturer, who is it?

Although many of us think Surefire is the best, in terms of sales volume, they're far from the largest. In fact, I would even guess that Streamlight has higher sales numbers then Surefire. Someone posted that Maglight is the largest but I have to even wonder about that. I would guess that perhaps Eveready, Rayovac and perhaps even Coleman might be at or near the top in terms of flashlight sales. You see these three brands at every department store and you'll see Eveready and Rayovac at drugstores, convenient stores, etc.

This is all speculation on my part but has anybody done any research and have information on the sales volume and ranks of some of these companies?
