Pretty common, about as common as the wagon wheel effect in 24fps film movies. In just the same way, the item can appear to stop, run slow, or run backwards, just as with film. No it does not have to be the only light source, just the nearest one to the machinery.
Fluorescent tubes are most noticeable, LEDs a little less. Tungsten or Halogen are the only sensible option for workpiece illumination.
- ouid 8y agoI believe halogen is also tungsten.
- NeedMoreTea 8y agoIt is. Just running at higher temperature. They tend to be marketed as something separate and distinct though.

- NeedMoreTea 8y agoOh I agree, but a surprising number of LED bulbs have some degree of flicker, even from those makes you might expect to do better. A purpose made work lamp should get it right though. Hopefully. Maybe. For my hobby stuff, I just bought a couple of spare halogens that should see me out.
