Good afternoon,
I’m new to the forum, but not really to replica prop lightsabers. I built my first Vader saber using a 3-cell heiland in the late 90’s. Even though it was not an MPP flash, I had to convince the dealer I wasn’t doing it for Star Wars. So I learned as much as I could about vintage photography. I remember trying to build a working saber using the tech of the time, plasma tubes. LED would never have occurred to me back then.
