EL wire is different, it's higher voltage AC making a magnetic field and exciting a phosphor, it's actually a continuous strip of illuminating material. This is small, dense LEDs in a strip.

LED uses EL effect of diode, EL wire uses EL effect of compounds dispersed in a material. Technically related, but this is based on tiny LEDs on a flexible PCB covered in the yellow LED goo. It's the same type of strip as ones used for retro look LED lightbulbs.

No, those are more similar to old fluorescent bulbs.
