My old (20+ years) Magcharger has a really odd shaped beam/center spot to it. It has dark spots in it and is very oval or elongated, regardless of how it is adjusted. My Stinger and Strion have nice round center spots, as do my Surefires. Is there something likely wrong with the bulb or reflector in my Magcharger that I should look at fixing or is this just characteristic of its design. I just started noticing it when I got more "into" LED flashlghts a few months back, don't really recall how long its been that way. Even though its large, I still use the Magcharger with regularity.
