I see.
I understand the point Red Eagle made regarding high frequency and dwell time, however, my experience with my simple circuit has shown me that reduced dwell time (on time) does lower amp draw, but at the cost of illumination. Push 300ma @ 100hz gives pretty much the same light as 300ma @ 6kHz. But if you set it draw 300ma @ low frequency and raise the frequency without adjusting dwell your light output will decrease, but your amp draw goes down. I can get the globe to glow dimly at less than 50ma with careful tuning, but I wonder what the point is besides a night light for my little girl
Of course this is a very simple circuit, and probably fails to show exotic behaviour others have claimed/seen.
I have noticed too that charging is stronger when the frequency is lower (amperage adjusted to eliminate that variable), however I rarely charge anything on the backend, it just doesnt cut the mustard anywhere near a 1 to 1 charge. This has been noted before by others too. I was actually thinking along the lines of Lidmotors latest experiment and using it to run a series of LED's and/or charge much smaller batteries more efficiently.
In regards to "sweet spots" I tune according to output light. Pushing 200-300 ma gives good light @ low power, and from about 500ma on it increases again. So I guess there are sweet spots. There is no reason to push, say 600ma, if the same light can be had for 500.
