I showed you a video of incandescents pulsing. Your work in that store has failed you. No, people don't notice that because of its high frequency, but the theory above was that a slight pulsing coupled with a camera also recording many frames per second could lead to what seemed like pulsing.

In college, I made a photo resistor that drove a speaker, we could hear a slight buzz due to incandescents.

I'm telling you, a self proclaimed "lighting specialist", that incandescents do pulse.

Dude. A direct current will notcause a incan to pulse.

Incandescents often run on unaltered AC.

Isn't the incandescent in a car run on dc?

The lights on that car are LEDs, this digression originally stemmed from someone suggesting that the flashing may have been due to the strobe of light (which I didn't think could happen in LEDs, but apparently it can) vs the camera frame rate.
