Mike:
yes these ar rough service incandescent lamps. Ironically, they're less efficient than regular incandescents (which are the banned ones). So they banned the most efficient incandescent lamps and they're keeping the less efficient ones. :8)

joe_347V:
Yeah, I wonder if a side effect from the ban is people upsizing bulb wattages (40w regular to 60w rough service) to compensate for the reduced lumens and end up wasting more energy. :8)

Another option is traffic signal bulbs which are still legal but are also less efficient. 

Mike:
plus most rough service lamps are 130V so combine that with the thicker filament you have a duller more yellow light, fewer lumens per watt, an overall it's less efficient, though life is improved a lot. so it's worth it to use them if the fixture is in a hard-to-get spot.

NiMo:
Also, Traffic Signal lamps can only be burned base down to base horizontal.
