If that’s old-school it’ll be neon, modern ones get the same look with LEDs. If it’s flickering slightly, it’s neon.
Large ones are pretty rare these days, because they’re horribly inefficient at turning electricity into light. The main place you’ll still find them are as heating lamps (for things like terrariums).

I thought they used incandescent lights for those, and some (like the terrarium heaters) aren’t even incandescent, they’re just ceramic resistance heaters that fit into an E26 base (screw-in light fixture).
They definitely use incandescent globes for heating as well. I just remember when I had fish, the shops would advertise neon heat lamps for terrariums. (I think it might have had something to do with infrared heating, but I’ve never had a terrarium so I’m kinda guessing now.)
LEDs will flicker without smoothing circuits too. Great circuits will have capacitors to smooth out the ac cycling and diode rectifiers to get power in both halves of the phase. But for $50c less, they can skip that and trust that the customer won’t make a purchase decision based on an indicator light. If the item or your eyes move quickly, you’ll likely catch them blinking like stop motion at 50/60hz
I can understand why people make this mistake. The word sure seems like a place where we’d use “hyper” instead of “hypo,” because it’s an above average sense of being unhealthy, and “hypo” tends to indicate below average.
However, the word “hypochondriac” comes from a Greek word meaning “under the cartilage (of the breastbone),” referring to the upper area of the abdomen, which in old school medicinal thought was where we kept our anxiety about our health.
Thus the “hypo” in “hypochondriac” has nothing to do with the amount of anxiety, but rather the imaginary location of that anxiety.

I definitely remember a specific neon light over my head in class giving me a headache once, but I think it had a problem at was flickering a bit slower than normal

Convinced these give me a headache but I feel like a hypercondriac for saying so…

Interesting :) I knew I was winging it…

Flicker can trigger an epileptic attack so maybe you want to check that out you two.
