   60 watt bulb. this means that you really need a variety of lamps.

   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.

   Maybe a flood light which I think are still available for 150w.

   I thought Trump relaxed that law.
