Abe,
We used the light every night and it was enough illumination. The secret (if there is one) is that the Hozuki light puts all its lumens into a downward broad cone of light. None of the light is 'wasted' lighting the upper area of the tent. In fact, we often dimmed the light when we were just sitting and eating. Unbeatable in my book.
David likes the Black Diamond Orbit, and it's a darned fine light, too. My first one had problems and had to be sent back for replacement. The battery life on my second one is better, but shorter than I'd prefer. Light output is excellent from the Orbit, which radiates 360 much like a conventional lantern. If you want a light which can sit on a surface, the BD Orbit is a great choice.
Incidentally, I've always got a headlamp on when it's dark in bear country. If I end up flushed out of the tent somehow, I don't want to be stumbling around in the dark brush.
