They do still allow a few varieties. One such variety is Rough Service       lamps. Im kinda        wondering since I assume that a 40W rough service light still uses 40w? Since       that's what is on the packaging. My understanding is that they have thicker       filaments, which would draw more wattage. But I think this would just give off       less light. I        respect the engineers who put the data on the package so I assume that a 40w       is still 40 watts. It would be wrong to put anything else on the package.       >       > Of course if I wanted a larger bulb 60w 100w 150w. I'm not sure what to use.       Maybe a flood light which I think are still available for 150w.       >       > Finally, I wonder if I ordered incandescent lamps from Amazon, if they would       be stopped at the boarder ???       >       > Thoughts ??       >                     I thought Trump relaxed that law.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
