Amber neon bulb (brand new)

I received a bag of neon bulb samples from my mom's friend in around 2010, who is used to work in an electronic components company. This bag of samples contained 4 amber bulbs and 2 blue bulbs; 2 of the amber bulbs are used to replace bad bulbs in power strips, the other one is lost and this is the only amber bulb that still free.
This bulb is powered without a ballast resistor in this demo. To use these bulbs properly, always connect a ballast resistor.
Warning: High voltage is applied to power these neon bulbs. If you are going to play around with these bulbs or any other high voltage components, safety precautions must be taken or you may have a risk of electric shock.

You got yourself a new neon indicator bulb, neon indicator bulbs, mainly contain the neon gas, but they sometimes contain argon nitrogen, which makes UV light so they use phosphorus for those neon indicator bulbs, Swiss nitrogen argon, gas Foster glow, blue and green so you have a red standard neon indicator bulb and two argon nitrogen ones with blue and green phosphorus

How this neon bulb didn't exploded and tripped the main circuit breaker, if you didn't operated it with a ballasting resistor?

It is not directly from the mains, but a fluorescent lantern.
