A group of us have been making simple mods using a Mag host, an array of 123s, and a high wattage lamp. It's difficult finding just the right bulb for a given array of 123s (or for any voltage source).
Of course we can lower the battery voltage or raise the rated bulb voltage, but that makes things dimmer. We want to walk on the wild side. We have been trying to walk that walk, but we're losing a lot of bulbs.
The SureFire A2 has circuitry to ramp up the voltage relatively slowly so that bulb life is lengthened. I presume it also reduces the risk of the bulb flashing. The circuit also regulates.
What we could use is a simple circuit that addresses only the initial transient problem. Does anyone have any ideas -- maybe something with a transistor and a few resistors and diodes?

P.S. ( Edit) Recently zmoz was looking for a circuit to cuttoff charging when a certain voltage is reached. Some suggested circuits are found here. It would be nice to find something like what was discussed.
