Questions from a flashbulb neophyte. Am I better off to buy a pre-manufactured flashgun or make my own? I like the small size of a folding reflector, but I'm concerned about odd-ball batteries. If I "roll my own", is a screw base (say for a #11 or #22 bulb) the same type as for a household light bulb? Any suggestions for materials for a home-made?
What about voltage and current? I've read that 3 volts DC is the minimum to ignite a bulb but I wonder if more is better. For example, if I connect four batteries in series to get 8.8 volts, will I have a better chance of ignition?
Regarding current, is there a significant current requirement during ignition? For example, a 9 volt battery has about the same voltage as four "D" cells in series, but would it fail to start or sustain ignition because it has a much lower current capacity?
Thanks for staying with me: I'm almost done. If I immerse a flashgun underwater, need I be concerned about a voltage short? I realize corrosion would eventually be a problem but I wouldn't worry about it if the flashgun is home-made. Thanks again.
