I won't say it's the worst flashlight ever, but my "vintage" Pelican SwatLite is probably the worst in my accumulation (NOT collection) of lights. I purchased this 4 C-cell, magnetically switched, dual filament, two level light way back in the mid-80's, and seemed fairly cool at the time. I think Pelican was (at least by it's name) marketing this light toward the LEO and related markets. It's your typical Pelican rugged construction, but the beam pattern (at both levels) seems best suited to an Astronomy science project demonstrating what nebulae look like. In any case, it's still kind of a nice relic to have hanging around in the storeroom, but I have no idea where to find a replacement bulb when this one blows.
