    Half as bright due to phase cancellation

    What is out-of-phase when the load is a simple resistive wire anyway?????

    The wire in the bulb doesn't care... It's performance is not phase sensitive

    Certainly not using old incandescent bulbs. The light comes from a super-heated filament. The light comes from the bulb because the wire is hot. The glowing of the wire does not does not oscillate appreciably with the supply voltage because the heated filament does not change temp much between cycles. Besides, the 60-cycle AC current is so low relative to the wavelength of the light that it is irrelevant.

    Now as you move past the two bulbs you might experience some comb-filtering and interesting color effects, but the speed at which you moved past the two bulbs would be pretty darned fast. Like close to the speed of light. You would be really-really long, and time would go by real slow based on your perception of time at that speed...
    I was absolutely certain that you would know. I'm glad I asked.
