I wouldn't go so far as "don't do it" - if you're dimming it, a little shading probably isn't that much of a problem anyway. The manufacturers say "don't do it " to cover their asses. |

Wrong - the filament surface get distinctly granular and weak spots are inevitable. With DC, the tungsten actually migrates along the filament length - it gets thinner at one end, and guess what happens next. |
