I apologize for the long posts. I'll try to do better.

I did forget to mention one other strange effect I found. When running on a singe AA 1.25v, I could stand a small medium strength neo magnet on top of the camera coil and I could dim or make it a little brighter than without it by rotating it. My guess is the coil is just below saturation and the magnet, when in the right position, adds a little extra to the cores field that is collapsing with it increasing the output.

This lead me to yet another thought I want to look into. There has to be a formula somewhere for calculating the max saturation mass of a given core size. One that would indicate the gauge wire vs voltage, turns or resistance needed...ect...... I have never seen this posted.
