We saw this problem (low light intensity) this past weekend. A couple of observations I made:
When powering the light from a battery, you should disconnect when not actually trying to acquire the light. The debugging dimension has a different temporal scale than the physical world, and the battery is living in the latter. It appears that one charge is good for testing one - or at maximum, two - ideas or one configuration error.
When packing 10 lbs in a 5 lb box, like we've done with all the wire, ballasts, and bulbs in the light enclosure, you might expect that the light performance may not be optimal. Especially when the light gets put together in a big rush because you have something more important to do - like debugging camera code. Shadows of a wiring rats nest projected onto the diffuser are probably not the best thing to calibrate to.
When all else fails, plug the camera into the LabView CMUcam GUI and take a peek at what it is seeing, rather than tweaking settings blindly while the battery discharges.
