|    Wattage of rough service incandecent bul    |

      From: stevwolf58@gmail.com              I have build a series load test light. eg. you plug a load in and it runs in       series through a lamp, in case there is a short, the lamp takes up the load,       so as to not blow a fuse. The lamp you use should be 3 x's the load. eg 20       watt load should have a        60 watt bulb. this means that you really need a variety of lamps.              Once finished I realized that getting an incandescent light bulb is not so       easy since the government has restricted the manufacture and importation of       them. 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 ??              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
