If they are true incandescent bulbs, with an old style "squirrel cage" filament, then I agree entirely. Such lamps have an appalling efficiency, even worse than modern incandescent lamps. Vendors of such lamps often call them "carbon filament" which is untrue. They do not even look like carbon filament lamps, they use a tungsten filament and somewhat resemble the very early tungsten lamps.
It is however possible, IMHO, that some of the lamps that you have observed are in fact LED "filament" bulbs, these have a good efficiency and may be used freely if they produce the desired effect.


I don't know the correct term but I believe those are the ones.
