The information in question comes from another website where the author (a professional handyman) explained that it's possible to over-tighten light bulbs, bending the contact within the socket to a point where it doesn't make firm contact with the bulb. The light flickers, over-stressing the filament with frequent on-off cycles, and making it "burn out" prematurely. Lewis found that information and shared some of it...
"Each light bulb should be screwed in to a point at which its tip touches a tiny filament that conducts electricity, sending it into the bulb."No, Jared, there's no "tiny filament": the filament is inside the bulb. What your source was discussing was, to use their exact words, a "brass tab at base of socket." If that gets flattened by overenthusiastic bulb installers, subsequent bulbs may not make a clean contact and thus flicker while in use. Alternatively, a tiny arc between bulb and contact may melt a hole in the solder at the base of the bulb, allowing air to enter what is supposed to be a vacuum and thus causing the bulb to burn out. This latter is, apparently, what Lewis meant by this reword job:
"The impact is a small electrical arc that creates extreme heat and begins to melt the soldering [sic]."
Yeah, sure... we're gonna take electrical safety suggestions from some twerp who "has completed doctoral work in American history," also known as today's Dumbass of the Day.
