Everybody is giving good advice, and to answer your original question, I've found LED based flashlights that have a wide spread also work really well. I picked up Home Depot model that has a beam adjustment to allow it to cover the area seen by the camera. I also picked up a version from probably the same store that had a Red, Blue, and White toggle -- though the beam was a bit narrow. I've also found all sorts of useful lighting near the cash register used for task lighting. Be careful of how you power them, but there are lots of novelty lights that clip onto hat brims as well.
