Other than some Philips frosted fan bulbs I mentioned elsewhere in this thread, my experience with rough service bulbs has been those labeled as "Good for trouble lights". Weird, overly warm color, more so than your run-of-the-mill light bulbs.


Looking at 75W bulbs, the rough service bulb is 62% of the light output of a normal bulb. Part of this is losses from more filament supports. But they probably run the filament at a lower temperature to make it more shock resistant. Lower temperature shifts the spectrum toward the red.
